  • Managing Operational Risk of Financial Services Processes – part 1/ 2

    - by Sanjeevio
    Financial institutions view compliance as a regulatory burden that incurs a high initial capital outlay and recurring costs. By its very nature regulation takes a prescriptive, common-for-all, approach to managing financial and non-financial risk. Needless to say, no longer does mere compliance with regulation will lead to sustainable differentiation.  Genuine competitive advantage will stem from being able to cope with innovation demands of the present economic environment while meeting compliance goals with regulatory mandates in a faster and cost-efficient manner. Let’s first take a look at the key factors that are limiting the pursuit of the above goal. Regulatory requirements are growing, driven in-part by revisions to existing mandates in line with cross-border, pan-geographic, nature of financial value chains today and more so by frequent systemic failures that have destabilized the financial markets and the global economy over the last decade.  In addition to the increase in regulation, financial institutions are faced with pressures of regulatory overlap and regulatory conflict. Regulatory overlap arises primarily from two things: firstly, due to the blurring of boundaries between lines-of-businesses with complex organizational structures and secondly, due to varying requirements of jurisdictional directives across geographic boundaries e.g. a securities firm with operations in US and EU would be subject different requirements of “Know-Your-Customer” (KYC) as per the PATRIOT ACT in US and MiFiD in EU. Another consequence and concomitance of regulatory change is regulatory conflict, which again, arises primarily from two things: firstly, due to diametrically opposite priorities of line-of-business and secondly, due to tension that regulatory requirements create between shareholders interests of tighter due-diligence and customer concerns of privacy. For instance, Customer Due Diligence (CDD) as per KYC requires eliciting detailed information from customers to prevent illegal activities such as money-laundering, terrorist financing or identity theft. While new customers are still more likely to comply with such stringent background checks at time of account opening, existing customers baulk at such practices as a breach of trust and privacy. As mentioned earlier regulatory compliance addresses both financial and non-financial risks. Operational risk is a non-financial risk that stems from business execution and spans people, processes, systems and information. Operational risk arising from financial processes in particular transcends other sources of such risk. Let’s look at the factors underpinning the operational risk of financial processes. The rapid pace of innovation and geographic expansion of financial institutions has resulted in proliferation and ad-hoc evolution of back-office, mid-office and front-office processes. This has had two serious implications on increasing the operational risk of financial processes: ·         Inconsistency of processes across lines-of-business, customer channels and product/service offerings. This makes it harder for the risk function to enforce a standardized risk methodology and in turn breaches harder to detect. ·         The proliferation of processes coupled with increasingly frequent change-cycles has resulted in accidental breaches and increased vulnerability to regulatory inadequacies. In summary, regulatory growth (including overlap and conflict) coupled with process proliferation and inconsistency is driving process compliance complexity In my next post I will address the implications of this process complexity on financial institutions and outline the role of BPM in lowering specific aspects of operational risk of financial processes.

  • Iterative and Incremental Principle Series 4: Iteration Planning – (a.k.a What should I do today?)

    - by llowitz
    Welcome back to the fourth of a five part series on applying the Iteration and Incremental principle.  During the last segment, we discussed how the Implementation Plan includes the number of the iterations for a project, but not the specifics about what will occur during each iteration.  Today, we will explore Iteration Planning and discuss how and when to plan your iterations. As mentioned yesterday, OUM prescribes initially planning your project approach at a high level by creating an Implementation Plan.  As the project moves through the lifecycle, the plan is progressively refined.  Specifically, the details of each iteration is planned prior to the iteration start. The Iteration Plan starts by identifying the iteration goal.  An example of an iteration goal during the OUM Elaboration Phase may be to complete the RD.140.2 Create Requirements Specification for a specific set of requirements.  Another project may determine that their iteration goal is to focus on a smaller set of requirements, but to complete both the RD.140.2 Create Requirements Specification and the AN.100.1 Prepare Analysis Specification.  In an OUM project, the Iteration Plan needs to identify both the iteration goal – how far along the implementation lifecycle you plan to be, and the scope of work for the iteration.  Since each iteration typically ranges from 2 weeks to 6 weeks, it is important to identify a scope of work that is achievable, yet challenging, given the iteration goal and timeframe.  OUM provides specific guidelines and techniques to help prioritize the scope of work based on criteria such as risk, complexity, customer priority and dependency.  In OUM, this prioritization helps focus early iterations on the high risk, architecturally significant items helping to mitigate overall project risk.  Central to the prioritization is the MoSCoW (Must Have, Should Have, Could Have, and Won’t Have) list.   The result of the MoSCoW prioritization is an Iteration Group.  This is a scope of work to be worked on as a group during one or more iterations.  As I mentioned during yesterday’s blog, it is pointless to plan my daily exercise in advance since several factors, including the weather, influence what exercise I perform each day.  Therefore, every morning I perform Iteration Planning.   My “Iteration Plan” includes the type of exercise for the day (run, bike, elliptical), whether I will exercise outside or at the gym, and how many interval sets I plan to complete.    I use several factors to prioritize the type of exercise that I perform each day.  Since running outside is my highest priority, I try to complete it early in the week to minimize the risk of not meeting my overall goal of doing it twice each week.  Regardless of the specific exercise I select, I follow the guidelines in my Implementation Plan by applying the 6-minute interval sets.  Just as in OUM, the iteration goal should be in context of the overall Implementation Plan, and the iteration goal should move the project closer to achieving the phase milestone goals. Having an Implementation Plan details the strategy of what I plan to do and keeps me on track, while the Iteration Plan affords me the flexibility to juggle what I do each day based on external influences thus maximizing my overall success. Tomorrow I’ll conclude the series on applying the Iterative and Incremental approach by discussing how to manage the iteration duration and highlighting some benefits of applying this principle.

  • On The Road with the HR Community

    - by Kathryn Perry
    A guest post by Steve Boese, Director, Talent Strategy, Oracle One of the best ways to connect with and to get a feel for what is on the minds of Human Resources leaders is to get out of the office and hit the road. I’ve had the great honor to attend and/or present at a number of events recently, including the massive SHRM Annual Conference, the HR Florida Conference, and Taleo World in Chicago. These events, and many others, offer solution providers, talent management professionals, business leaders, and even more casual observers of the Human Resources field with tremendous opportunities to connect, to share information, and to learn from each other. Attending the conferences also give people a sense of how they can improve and enhance their skills and knowledge, learn about the latest workforce technologies, and bring new and innovative ideas back to their organizations. And sure, the parties and conference swag can be pretty nice as well! If you attend a few of these industry events, one of the most beneficial by-products that you can emerge with -- whether you are on the front lines in HR at your organization, or as we are at Oracle, in the business of developing and delivering innovative and impactful technology solutions to our customers -- is to get a larger sense of the big ideas and major trends, concerns, and challenges facing organizations all across the landscape, and to be able to better understand how your strategies and solutions can be improved with this greater perspective. So what are HR folks discussing and debating? What questions and problems keep them up at night? What are the bloggers and large community of HR social media enthusiasts buzzing about? From my perspective some of the common themes you see over and again across the HR community break down (broadly), into three main areas: Talent attraction - How can we locate, attract, recruit, and hire the best talent possible? What new strategies, approaches, and technologies can help us in this critically important area? What role do external social networks like LinkedIn, Facebook, and Twitter play in the increasingly competitive search for talent? Talent Retention - How can we make sure to keep that talent on our team? What engagement, development, recognition, and compensation tools can help us in this regard? How can we continue, (or become), an employer of choice? What is our unique and compelling employer value proposition? Talent Empowerment - How can we put our employees in the best position to succeed? What can we do to better align our talent with the organization’s mission and goals, while simultaneously providing the best and most driven to succeed individuals a clear path to achieve their career goals and aspirations? How can new technologies, particularly social and collaboration tools help in this area? While these are the ‘big themes’ that I know I have seen this year, certainly they are not really new, nor are they likely to fundamentally change in the next year or two. I think the reason is that at the core of any successful enterprise is a collection of smart, interested, engaged, challenged, and empowered group of people. And that was likely the case 10 or 20 years ago, and will probably be the case 10 or 20 years into the future. But what has changed, and what you can see -- evidenced by simply following the Twitter backchannel for an event and by reading some of the many fantastic HR blogs out there -- is that the HR professional's ability, along with technology solution providers like Oracle, to connect, to more openly share information with each other, and to make each other better in the process, (and to create new, improved, and more innovative solutions), has never been greater. And I think it is with this heretofore unprecedented level of opportunity to connect with other members of the community that HR professionals will be better equipped to help their organizations attract, retain, and empower their teams. We at Oracle HCM look forward to continuing to meet, engage, and connect with the HR community in the coming months. Until then -- follow us on Twitter and Facebook.

  • To SYNC or not to SYNC – Part 4

    - by AshishRay
    This is Part 4 of a multi-part blog article where we are discussing various aspects of setting up Data Guard synchronous redo transport (SYNC). In Part 1 of this article, I debunked the myth that Data Guard SYNC is similar to a two-phase commit operation. In Part 2, I discussed the various ways that network latency may or may not impact a Data Guard SYNC configuration. In Part 3, I talked in details regarding why Data Guard SYNC is a good thing, and the distance implications you have to keep in mind. In this final article of the series, I will talk about how you can nicely complement Data Guard SYNC with the ability to failover in seconds. Wait - Did I Say “Seconds”? Did I just say that some customers do Data Guard failover in seconds? Yes, Virginia, there is a Santa Claus. Data Guard has an automatic failover capability, aptly called Fast-Start Failover. Initially available with Oracle Database 10g Release 2 for Data Guard SYNC transport mode (and enhanced in Oracle Database 11g to support Data Guard ASYNC transport mode), this capability, managed by Data Guard Broker, lets your Data Guard configuration automatically failover to a designated standby database. Yes, this means no human intervention is required to do the failover. This process is controlled by a low footprint Data Guard Broker client called Observer, which makes sure that the primary database and the designated standby database are behaving like good kids. If something bad were to happen to the primary database, the Observer, after a configurable threshold period, tells that standby, “Your time has come, you are the chosen one!” The standby dutifully follows the Observer directives by assuming the role of the new primary database. The DBA or the Sys Admin doesn’t need to be involved. And - in case you are following this discussion very closely, and are wondering … “Hmmm … what if the old primary is not really dead, but just network isolated from the Observer or the standby - won’t this lead to a split-brain situation?” The answer is No - It Doesn’t. With respect to why-it-doesn’t, I am sure there are some smart DBAs in the audience who can explain the technical reasons. Otherwise - that will be the material for a future blog post. So - this combination of SYNC and Fast-Start Failover is the nirvana of lights-out, integrated HA and DR, as practiced by some of our advanced customers. They have observed failover times (with no data loss) ranging from single-digit seconds to tens of seconds. With this, they support operations in industry verticals such as manufacturing, retail, telecom, Internet, etc. that have the most demanding availability requirements. One of our leading customers with massive cloud deployment initiatives tells us that they know about server failures only after Data Guard has automatically completed the failover process and the app is back up and running! Needless to mention, Data Guard Broker has the integration hooks for interfaces such as JDBC and OCI, or even for custom apps, to ensure the application gets automatically rerouted to the new primary database after the database level failover completes. Net Net? To sum up this multi-part blog article, Data Guard with SYNC redo transport mode, plus Fast-Start Failover, gives you the ideal triple-combo - that is, it gives you the assurance that for critical outages, you can failover your Oracle databases: very fast without human intervention, and without losing any data. In short, it takes the element of risk out of critical IT operations. It does require you to be more careful with your network and systems planning, but as far as HA is concerned, the benefits outweigh the investment costs. So, this is what we in the MAA Development Team believe in. What do you think? How has your deployment experience been? We look forward to hearing from you!

  • Webcast Q&A: Hitachi Data Systems Improves Global Web Experiences with Oracle WebCenter

    - by kellsey.ruppel
    Last Thursday we had the third webcast in our WebCenter in Action webcast series, "Hitachi Data Systems Improves Global Web Experiences with Oracle WebCenter", where customer Sean Mattson from HDS and Rob Vandenberg from Oracle Partner Lingotek shared how Oracle WebCenter is powering Hitachi Data System’s externally facing website and providing a seamless experience for their customers. In case you missed it, here's a recap of the Q&A.   Sean Mattson, Hitachi Data Systems  Q: Did you run into any issues in the deployment of the platform?A: There were some challenges, we were one of the first enterprise ‘on premise’ installations for Lingotek and our WebCenter platform also has a lot of custom features.  There were a lot of iterations and back and forth working with Lingotek at first.  We both helped each other, learned a lot and in the end managed to resolve all issues and roll out a very compelling solution for HDS. Q: What has been the biggest benefit your end users have seen?A: Being able to manage and govern the content lifecycle globally and centrally and at the same time enabling the field to update, review and publish the incremental content changes without a lot of touchpoints has helped us streamline and simplify the entire publishing process. Q: Was there any resistance internally when implementing the solution? If so, how did you overcome that?A: I wouldn't say resistance as much as skepticism that we could actually deploy an automated and self publishing solution.  Even if a solution is great, adoption of a new process can be a challenge and we are still pursuing our adoption targets.  One of the most important aspects is to include lots of training and support materials and offer as much helpdesk type support as needed to get the field self sufficient and confident in the capabilities of the system.  Rob Vandenberg, Lingotek  Q: Are there any limitations regarding supported languages such as support for French Canadian and Indian languages?A: Lingotek supports all language pairs. Including right to left languages and double byte languages such as Chinese, Japanese and Korean Q: Is the Lingotek solution integrated with the new 11g release of WebCenter Sites? A: Yes! In fact, Lingotek is the first OVI partner for Oracle WebCenter Sites  Q: Can translation memories help to improve the accuracy of machine translation?A: One of the greatest long term strategic benefits of using Lingotek is the accumulation of translation memories, or past human translations. These TMs can be used to "train" statistical machine translation engines to have higher and higher quality. This virtuous cycle is ongoing and will consistently improve both machine and human translations.  Q: We have existing translation memories from previous work with our translation service provider. Can they be easily imported in to the Lingotek solution for re-use? Q: Yes, Lingotek is standards compliant. We support TM import in both the TMX and XLIFF formats. Q: If we use Lingotek as a service to do our professional translation and also use the Lingotek software solution, do we get the translation memories to give us a means of just translating future adds and changes ourselves? A: Yes, all the data is yours, always. Lingotek can provide both the integrated translation software as well as the professional translation services. All the content and translation memories are yours. Q: Can you give us an example of where community translation has proved to be successful?A: The key word here is community. If you have a community that cares about you, your content, and the rest of the community, then community translation can work for you. We've seen effective use cases in Product User Groups content, Support Communities, and other types of User Generated content, like wikis and blogs.   If you missed the webcast, be sure to catch the replay to see a live demonstration of WebCenter in action!   Hitachi Data Systems Improves Global Web Experiences with Oracle WebCenter from Oracle WebCenter

  • Acceptance tests done first...how can this be accomplished?

    - by Crazy Eddie
    The basic gist of most Agile methods is that a feature is not "done" until it's been developed, tested, and in many cases released. This is supposed to happen in quick turnaround chunks of time such as "Sprints" in the Scrum process. A common part of Agile is also TDD, which states that tests are done first. My team works on a GUI program that does a lot of specific drawing and such. In order to provide tests, the testing team needs to be able to work with something that at least attempts to perform the things they are trying to test. We've found no way around this problem. I can very much see where they are coming from because if I was trying to write software that targeted some basically mysterious interface I'd have a very hard time. Although we have behavior fairly well specified, the exact process of interacting with various UI elements when it comes to automation seems to be too unique to a feature to allow testers to write automated scripts to drive something that does not exist. Even if we could, a lot of things end up turning up later as having been missing from the specification. One thing we considered doing was having the testers write test "scripts" that are more like a set of steps that must be performed, as described from a use-case perspective, so that they can be "automated" by a human being. This can then be performed by the developer(s) writing the feature and/or verified by someone else. When the testers later get an opportunity they automate the "script" for regression purposes mainly. This didn't end up catching on in the team though. The testing part of the team is actually falling behind us by quite a margin. This is one reason why the apparently extra time of developing a "script" for a human being to perform just did not happen....they're under a crunch to keep up with us developers. If we waited for them, we'd get nothing done. It's not their fault really, they're a bottle neck but they're doing what they should be and working as fast as possible. The process itself seems to be set up against them. Very often we end up having to go back a month or more in what we've done to fix bugs that the testers have finally gotten to checking. It's an ugly truth that I'd like to do something about. So what do other teams do to solve this fail cascade? How can we get testers ahead of us and how can we make it so that there's actually time for them to write tests for the features we do in a sprint without making us sit and twiddle our thumbs in the meantime? As it's currently going, in order to get a feature "done", using agile definitions, would be to have developers work for 1 week, then testers work the second week, and developers hopefully being able to fix all the bugs they come up with in the last couple days. That's just not going to happen, even if I agreed it was a reasonable solution. I need better ideas...

  • Something about Property Management or &hellip; the understanding of SharePoint Admins/roles ?!?

    - by Enrique Lima
    When I talk about SharePoint, for some reason it comes to my mind as if it were property management and all the tasks associated with it. So, imagine you have a lot ( a piece of land of sorts), you then decide there is something you want to do with it.  So, you make the choice of having a building built.  Now, in order to go forward with your plan, you need to check what the rules/regulations are.  Has is it been zoned residential, commercial, industrial … you get the idea.  This to me sounds like Governance.  The what am I to do given a defined set of rules. We keep on moving forward based on those rules.  And with this we start the process of building, the building process takes us to survey the land, identify what our boundaries are.  And as we go along we start getting the idea in our head as to what we will do as far as the building goes.  We identify the essentials of the building, basic services and such.  All in all, we plan.  And as with many things we do, we like solid foundations.  What a solid foundation looks like will depend on where and what we build.  The way buildings are built depends in many ways in being able to foresee the potential for natural disasters or to try to leverage the lay of the land.  Sound familiar?  We have done our Requirements Gathering. We have the building in place, we have followed the zoning rules, we have implemented services.  But we need someone to manage the building, now we move on to the human side of the story.  We want to establish a means to normalcy in the building, someone that can be the monitoring agent as to the “what’s going on?” of it.  This person will be tasked with making sure all basic services are functional, that measures are taken if there is an issue and so on.  Enter the Farm Administrator. In a way, we establish an extension of the rules to make sure the building and the apartments/offices build follow a standard set of rules too. Now, in turn you will have people leasing or buying the apartments/offices, they will be the keepers of that space.  So, now we are building sites, we have moved from having the building (farm) ready, to leasing/selling offices/apartments (site collections).  There will be someone assuming responsibility for those offices, that person will authorize or be informed about activities and also who not only gets a code into the building, but perhaps a key to the office.  Enter Site Collection Administrator.  And then perhaps we move on to the person that would be responsible for specifics within the office, for example a Human Resources Manager or Coordinator.  They will have specific control and knowledge about people.  A facilities coordinator, and so on.  I would translate that into Site Administrators. With that said then, we identify the following: Role Name Responsibility (but not limited to) Farm Administrator Infrastructure Site Collection Admin Policies for Content, Hierarchy, Recycle Bin, Security and Access Site Owner (Site Admin) Security and Access, Training, Guidance, Manage Templates All in all there are different levels of responsibility to be handled, but it is very important to understand what they are and what they mean. Here is a link to very well laid out explanation on this … http://www.endusersharepoint.com/2009/08/11/site-managers-and-end-user-expectations-roles-and-responsibilities/

  • Columnstore Case Study #1: MSIT SONAR Aggregations

    - by aspiringgeek
    Preamble This is the first in a series of posts documenting big wins encountered using columnstore indexes in SQL Server 2012 & 2014.  Many of these can be found in this deck along with details such as internals, best practices, caveats, etc.  The purpose of sharing the case studies in this context is to provide an easy-to-consume quick-reference alternative. Why Columnstore? If we’re looking for a subset of columns from one or a few rows, given the right indexes, SQL Server can do a superlative job of providing an answer. If we’re asking a question which by design needs to hit lots of rows—DW, reporting, aggregations, grouping, scans, etc., SQL Server has never had a good mechanism—until columnstore. Columnstore indexes were introduced in SQL Server 2012. However, they're still largely unknown. Some adoption blockers existed; yet columnstore was nonetheless a game changer for many apps.  In SQL Server 2014, potential blockers have been largely removed & they're going to profoundly change the way we interact with our data.  The purpose of this series is to share the performance benefits of columnstore & documenting columnstore is a compelling reason to upgrade to SQL Server 2014. App: MSIT SONAR Aggregations At MSIT, performance & configuration data is captured by SCOM. We archive much of the data in a partitioned data warehouse table in SQL Server 2012 for reporting via an application called SONAR.  By definition, this is a primary use case for columnstore—report queries requiring aggregation over large numbers of rows.  New data is refreshed each night by an automated table partitioning mechanism—a best practices scenario for columnstore. The Win Compared to performance using classic indexing which resulted in the expected query plan selection including partition elimination vs. SQL Server 2012 nonclustered columnstore, query performance increased significantly.  Logical reads were reduced by over a factor of 50; both CPU & duration improved by factors of 20 or more.  Other than creating the columnstore index, no special modifications or tweaks to the app or databases schema were necessary to achieve the performance improvements.  Existing nonclustered indexes were rendered superfluous & were deleted, thus mitigating maintenance challenges such as defragging as well as conserving disk capacity. Details The table provides the raw data & summarizes the performance deltas. Logical Reads (8K pages) CPU (ms) Durn (ms) Columnstore 160,323 20,360 9,786 Conventional Table & Indexes 9,053,423 549,608 193,903 ? x56 x27 x20 The charts provide additional perspective of this data.  "Conventional vs. Columnstore Metrics" document the raw data.  Note on this linear display the magnitude of the conventional index performance vs. columnstore.  The “Metrics (?)” chart expresses these values as a ratio. Summary For DW, reports, & other BI workloads, columnstore often provides significant performance enhancements relative to conventional indexing.  I have documented here, the first in a series of reports on columnstore implementations, results from an initial implementation at MSIT in which logical reads were reduced by over a factor of 50; both CPU & duration improved by factors of 20 or more.  Subsequent features in this series document performance enhancements that are even more significant.

  • Consumer Oriented Search In Oracle Endeca Information Discovery – Part 1

    - by Bob Zurek
    Information Discovery, a core capability of Oracle Endeca Information Discovery, enables business users to rapidly search, discover and navigate through a wide variety of big data including structured, unstructured and semi-structured data. One of the key capabilities, among many, that differentiate our solution from others in the Information Discovery market is our deep support for search across this growing amount of varied big data. Our method and approach is very different than classic simple keyword search that is found in may information discovery solutions. In this first part of a series on the topic of search, I will walk you through many of the key capabilities that go beyond the simple search box that you might experience in products where search was clearly an afterthought or attempt to catch up to our core capabilities in this area. Lets explore. The core data management solution of Oracle Endeca Information Discovery is the Endeca Server, a hybrid search-analytical database that his highly scalable and column-oriented in nature. We will talk in more technical detail about the capabilities of the Endeca Server in future blog posts as this post is intended to give you a feel for the deep search capabilities that are an integral part of the Endeca Server. The Endeca Server provides best-of-breed search features aw well as a new class of features that are the first to be designed around the requirement to bridge structured, semi-structured and unstructured big data. Some of the key features of search include type a heads, automatic alphanumeric spell corrections, positional search, Booleans, wildcarding, natural language, and category search and query classification dialogs. This is just a subset of the advanced search capabilities found in Oracle Endeca Information Discovery. Search is an important feature that makes it possible for business users to explore on the diverse data sets the Endeca Server can hold at any one time. The search capabilities in the Endeca server differ from other Information Discovery products with simple “search boxes” in the following ways: The Endeca Server Supports Exploratory Search.  Enterprise data frequently requires the user to explore content through an ad hoc dialog, with guidance that helps them succeed. This has implications for how to design search features. Traditional search doesn’t assume a dialog, and so it uses relevance ranking to get its best guess to the top of the results list. It calculates many relevance factors for each query, like word frequency, distance, and meaning, and then reduces those many factors to a single score based on a proprietary “black box” formula. But how can a business users, searching, act on the information that the document is say only 38.1% relevant? In contrast, exploratory search gives users the opportunity to clarify what is relevant to them through refinements and summaries. This approach has received consumer endorsement through popular ecommerce sites where guided navigation across a broad range of products has helped consumers better discover choices that meet their, sometimes undetermined requirements. This same model exists in Oracle Endeca Information Discovery. In fact, the Endeca Server powers many of the most popular e-commerce sites in the world. The Endeca Server Supports Cascading Relevance. Traditional approaches of search reduce many relevance weights to a single score. This means that if a result with a good title match gets a similar score to one with an exact phrase match, they’ll appear next to each other in a list. But a user can’t deduce from their score why each got it’s ranking, even though that information could be valuable. Oracle Endeca Information Discovery takes a different approach. The Endeca Server stratifies results by a primary relevance strategy, and then breaks ties within a strata by ordering them with a secondary strategy, and so on. Application managers get the explicit means to compose these strategies based on their knowledge of their own domain. This approach gives both business users and managers a deterministic way to set and understand relevance. Now that you have an understanding of two of the core search capabilities in Oracle Endeca Information Discovery, our next blog post on this topic will discuss more advanced features including set search, second-order relevance as well as an understanding of faceted search mechanisms that include queries and filters.

The focus of my talk was Mobile Technology in Human Resources, and while still a new and developing area, the enormous growth and ubiquitous presence of mobile devices and increasing importance of and demand for constant connectivity in both our personal and professional lives has put planning and developing a mobile HR technology strategy high on many organizations lists of priorities in 2012. Numerous studies have shown that the confluence of ever-rising sales of smartphones and tablets; and the increasing tendency for workers of all kinds to be more mobile and less tied down to traditional, fixed-location workplaces and what now seem like old-fashioned PC-centric and traditional computing environments are driving Human Resources leaders to think about how, where, when, and for whom that the deployment of mobile HR solutions will help them address their business needs, and put information in the hands of those that need it, when they need it, and on their preferred devices. In the session we talked about some of the potential opportunities for mobile HR technologies, from simple workflow-based approval capability, to employee directories and robust employee profiles, to more advanced use cases like internal social networking and location-based mobile recruiting applications. And truly we are just scratching the surface of the potential and the value that all kinds of HR-related mobile technologies will help deliver to enterprises in the coming years. Additionally, it was encouraging to talk with many of the HR leaders in attendance who expressed interest in these kinds of mobile HR technology opportunities, as well as to hear how some of them are already working on developing their own mobile strategies or experimenting with mobile solutions in their workforces. It was a fantastic meeting and I’d like to express my thanks to Kim Bryant, IHRIM Atlanta/SE Board President, the other board members, and also the IHRIM Atlanta Chapter members and attendees at the event. If you are in the Atlanta area and are interested in HR and HR Technology, you can learn more about the programs and services that the Chapter has to offer at their website - http://www.ihrimatlantase.org/. And for people that are interested in what we at Oracle are working on in mobile, you can also sign up to receive the latest updates about the Oracle Fusion Applications tablet solutions, Oracle Fusion Tap, at https://fusiontap.oracle.com/.

  • Make the Time

    - by WonderOfItAll
    Took the little one to the pool tonight for swim lessons. Okay, Okay. They're not really lessons so much as they are "Hey, here's a few bucks, let me rent out a small section of your pool to swim around with my little one" Saw a dad at the pool. Bluetooth on, iPad in hand, and two year old somewhere around there. Saw a mom at the pool. Arguing with her five year old to NOT take a shower after swimming. Bluetooth on, iPad in hand, work laptop open on stadium seats. Her reasoning for not wanting the child to shower "Look, I have to get this stuff to the office by 6:30, we don't have time for you to shower. Let's go" Wait, isn't the whole point of this little experience called Mommy and Me (or, as in my case, Daddy and Me). Wherein Mommy/Daddy is supposed to spend time with little one. Not with the Bluetooth. Not with the work laptop. Dad (yeah, the same dad from earlier), in the pool. Bluetooth off (it's not waterproof or I'm sure he would've had it on), two year old in hand and iPad somewhere put away. Getting frustrated with kid because he won't 'perform' on command. Here's a little exchange Kid: "I don't wanna get in the water" Dad: "Well, we're here for 30 minutes, get in the water" Kid: "No, don't wanna" Dad: "Fine, I'm getting in" and, true to his word, in he goes, off to swim. Kid: Crying Dad: "Well, c'mon" Kid: Walking to stands Dad: Ignoring kid Kid: At stands Dad: Out of pool, drying off. Frustrated. Grabs bag, grabs kid, leaves How sad. It really seems like I am living in a generation of parents who view their children as one big scheduled distraction to another. It's almost like the dad was saying "Look, little 2 year old boy, I have a busy scheduled. Right now my Outlook Calendar tells me that I have 30 mins to spend with you, so, let's go kid: PERFORM because I have the time" Really? Can someone please tell me when the hell this happened? When did spending time with your kid, spending time with your family, spending time with your spouse, etc... become a distraction? I've seen people at work all day Tweeting throughout the day, checked in with Four Square, IM up and running constantly so they can 'stay in touch' only to see these same folks come home and be irritated because their kids or their spouse wants to connect with the. I've seen these very same people leave the house, go to the corner bar/store/you-name-the-place to be 'alone' only to find them there, plugged in, tweeting away, etc, etc, etc I LOVE technology. I love working with technology. But I also know that I am a human being. A person who, by very definition, is a social being. I needed social interactions and contact--and, no, I'm not talking about the Social Graph kind of connections, I'm talking about those interactions which, *GASP* involve eye to eye contact and human contact. A recent study found that the number one complaint of kids is that they feel they have to compete with technology for their parents time and attention. The number one wish from high school kids? That there parents would turn off the computer/tv/cell phone at dinner. This, coming from high school kids. Shouldn't that tell you a whole helluva lot? So, do yourself a favor tomorrow. Plug into technology all day. Throw yourself into it. Be passionate about what you do. When you walk through the door to your family, turn it all off for 30 mins and be there with your loved ones. If you can manage to play Angry Birds, I'm sure you can handle being disconnected for 30 minutes. Make the time

  • Approach for packing 2D shapes while minimizing total enclosing area

    - by Dennis
    Not sure on my tags for this question, but in short .... I need to solve a problem of packing industrial parts into crates while minimizing total containing area. These parts are motors, or pumps, or custom-made components, and they have quite unusual shapes. For some, it may be possible to assume that a part === rectangular cuboid, but some are not so simple, i.e. they assume a shape more of that of a hammer or letter T. With those, (assuming 2D shape), by alternating direction of top & bottom, one can pack more objects into the same space, than if all tops were in the same direction. Crude example below with letter "T"-shaped parts: ***** xxxxx ***** x ***** *** ooo * x vs * x vs * x vs * x o * x * xxxxx * x * x o xxxxx xxx Right now we are solving the problem by something like this: using CAD software, make actual models of how things fit in crate boxes make estimates of actual crate dimensions & write them into Excel file (1) is crazy amount of work and as the result we have just a limited amount of possible entries in (2), the Excel file. The good things is that programming this is relatively easy. Given a combination of products to go into crates, we do a lookup, and if entry exists in the Excel (or Database), we bring it out. If it doesn't, we say "sorry, no data!". I don't necessarily want to go full force on making up some crazy algorithm that given geometrical part description can align, rotate, and figure out best part packing into a crate, given its shape, but maybe I do.. Question Well, here is my question: assuming that I can represent my parts as 2D (to be determined how), and that some parts look like letter T, and some parts look like rectangles, which algorithm can I use to give me a good estimate on the dimensions of the encompassing area, while ensuring that the parts are packed in a minimal possible area, to minimize crating/shipping costs? Are there approximation algorithms? Seeing how this can get complex, is there an existing library I could use? My thought / Approach My naive approach would be to define a way to describe position of parts, and place the first part, compute total enclosing area & dimensions. Then place 2nd part in 0 degree orientation, repeat, place it at 180 degree orientation, repeat (for my case I don't think 90 degree rotations will be meaningful due to long lengths of parts). Proceed using brute force "tacking on" other parts to the enclosing area until all parts are processed. I may have to shift some parts a tad (see 3rd pictorial example above with letters T). This adds a layer of 2D complexity rather than 1D. I am not sure how to approach this. One idea I have is genetic algorithms, but I think those will take up too much processing power and time. I will need to look out for shape collisions, as well as adding extra padding space, since we are talking about real parts with irregularities rather than perfect imaginary blocks. I'm afraid this can get geometrically messy fairly fast, and I'd rather keep things simple, if I can. But what if the best (practical) solution is to pack things into different crate boxes rather than just one? This can get a bit more tricky. There is human element involved as well, i.e. like parts can go into same box and are thus a constraint to be considered. Some parts that are not the same are sometimes grouped together for shipping and can be considered as a common grouped item. Sometimes customers want things shipped their way, which adds human element to constraints. so there will have to be some customization.

  • When should I use a Process Model versus a Use Case?

    - by Dave Burke
    This Blog entry is a follow on to https://blogs.oracle.com/oum/entry/oum_is_business_process_and and addresses a question I sometimes get asked…..i.e. “when I am gathering requirements on a Project, should I use a Process Modeling approach, or should I use a Use Case approach?” Not surprisingly, the short answer is “it depends”! Let’s take a scenario where you are working on a Sales Force Automation project. We’ll call the process that is being implemented “Lead-to-Order”. I would typically think of this type of project as being “Process Centric”. In other words, the focus will be on orchestrating a series of human and system related tasks that ultimately deliver value to the business in a cost effective way. Put in even simpler terms……implement an automated pre-sales system. For this type of (Process Centric) project, requirements would typically be gathered through a series of Workshops where the focal point will be on creating, or confirming, the Future-State (To-Be) business process. If pre-defined “best-practice” business process models exist, then of course they could and should be used during the Workshops, but even in their absence, the focus of the Workshops will be to define the optimum series of Tasks, their connections, sequence, and dependencies that will ultimately reflect a business process that meets the needs of the business. Now let’s take another scenario. Assume you are working on a Content Management project that involves automating the creation and management of content for User Manuals, Web Sites, Social Media publications etc. Would you call this type of project “Process Centric”?.......well you could, but it might also fall into the category of complex configuration, plus some custom extensions to a standard software application (COTS). For this type of project it would certainly be worth considering using a Use Case approach in order to 1) understand the requirements, and 2) to capture the functional requirements of the custom extensions. At this point you might be asking “why couldn’t I use a Process Modeling approach for my Content Management project?” Well, of course you could, but you just need to think about which approach is the most effective. Start by analyzing the types of Tasks that will eventually be automated by the system, for example: Best Suited To? Task Name Process Model Use Case Notes Manage outbound calls Ö A series of linked human and system tasks for calling and following up with prospects Manage content revision Ö Updating the content on a website Update User Preferences Ö Updating a users display preferences Assign Lead Ö Reviewing a lead, then assigning it to a sales person Convert Lead to Quote Ö Updating the status of a lead, and then converting it to a sales order As you can see, it’s not an exact science, and either approach is viable for the Tasks listed above. However, where you have a series of interconnected Tasks or Activities, than when combined, deliver value to the business, then that would be a good indicator to lead with a Process Modeling approach. On the other hand, when the Tasks or Activities in question are more isolated and/or do not cross traditional departmental boundaries, then a Use Case approach might be worth considering. Now let’s take one final scenario….. As you captured the To-Be Process flows for the Sales Force automation project, you discover a “Gap” in terms of what the client requires, and what the standard COTS application can provide. Let’s assume that the only way forward is to develop a Custom Extension. This would now be a perfect opportunity to document the functional requirements (behind the Gap) using a Use Case approach. After all, we will be developing some new software, and one of the most effective ways to begin the Software Development Lifecycle is to follow a Use Case approach. As always, your comments are most welcome.

  • Ruby on rails generates tests for you. Do those give a false sense of a safety net?

    - by Hamish Grubijan
    Disclaimer: I have not used RoR, and I have not generated tests. But, I will still dare to post this question. Quality Assurance is theoretically impossible to get 100% right in general (Undecidable problem ;), and it is hard in practice. So many developers do not understand that writing good automated tests is an art, and it is hard. When I hear that RoR generates the tests for you, I get very skeptical. It cannot be that easy. Testing is a general concept; it applies across languages. So does the concept of code contracts, it is similar for languages that support it. Code contracts do not generate themselves. The programmer must add the requirements and the promises manually, after doing some thinking about the algorithm / function. If a human gets it wrong, then the tools will propagate the error. Similarly with testing - it takes human judgement about what should happen. Tests do not write themselves, and we are far from the day when a business analyst can just have a conversation with a computer and tell it informally what the requirements are and have the computer do all the work. There is no magic ... how can RoR generate good tests for you? Please shed some light on this. Opinions are ok, for this is a community wiki. Thanks!

  • Programmatic skins in Flex

    - by Flexer
    Hi, I am having 2 problems creating programmatic skin for Canvas. First problem: I would like to have background with rounded corners and I am using GraphicsUtil.drawRoundRectComplex in order to have round corners for only the upper two corners. The problem is that drawRoundRectComplex takes for each corner one single parameter - the corner radius. However my scaleX and scaleY factors are different and in fact the corners are not properly rounded because I either can set the radius using scaleX or scaleY. Graphics.drawRoundRect is better because it takes two parameters for the corners - elipse width and height and then you could apply both scale factors but it doesn't allow me to specify different radius for different corners. I am looking for an idea how to use GraphicsUtil.drawRoundRectComplex when scaleX and scaleY are different. Second problem: Even though I set my programmatic skin through style - < the skin's updateDisplayList gets executed only once and after that somehow "backgroundImage" style gets "undefined" and my programmatic skin is not associated anymore to the Canvas instance. As a workaround I am setting on each resize event "backgroundImage" style again but this is ugly. What could cause such "silent" resetting of the "backgroundImage" style to undefined? Thanks!

  • Heuristic to identify if a series of 4 bytes chunks of data are integers or floats

    - by flint
    What's the best heuristic I can use to identify whether a chunk of X 4-bytes are integers or floats? A human can do this easily, but I wanted to do it programmatically. I realize that since every combination of bits will result in a valid integer and (almost?) all of them will also result in a valid float, there is no way to know for sure. But I still would like to identify the most likely candidate (which will virtually always be correct; or at least, a human can do it). For example, let's take a series of 4-bytes raw data and print them as integers first and then as floats: 1 1.4013e-45 10 1.4013e-44 44 6.16571e-44 5000 7.00649e-42 1024 1.43493e-42 0 0 0 0 -5 -nan 11 1.54143e-44 Obviously they will be integers. Now, another example: 1065353216 1 1084227584 5 1085276160 5.5 1068149391 1.33333 1083179008 4.5 1120403456 100 0 0 -1110651699 -0.1 1195593728 50000 These will obviously be floats. PS: I'm using C++ but you can answer in any language, pseudo code or just in english.

  • Is Annotation in Javascript? If not, how to switch between debug/productive modes in declarative way

    - by Michael Mao
    Hi all: This is but a curious question. I cannot find any useful links from Google so it might be better to ask the gurus here. The point is: is there a way to make "annotation" in javascript source code so that all code snippets for testing purpose can be 'filtered out' when project is deployed from test field into the real environment? I know in Java, C# or some other languages, you can assign an annotation just above the function name, such as : // it is good to remove the annoying warning messages @SuppressWarnings("unchecked") public class Tester extends TestingPackage { ... } Basically I've got a lot of testing code that prints out something into FireBug console. I don't wanna manually "comment out" them because the guy that is going to maintain the code might not be aware of all the testing functions, so he/she might just miss one function and the whole thing can be brought down to its knees. One other thing, we might use a minimizer to "shrink" the source code into "human unreadable" code and boost up performance (just like jQuery.min), so trying to match testing section out of the mess is not possible for plain human eyes in the future. Any suggestion is much appreciated.

  • GridView: How can I get rid of extra space from my GirdView object?

    - by Lajos Arpad
    Hello, I'm writing an application for Android phones for Human vs. Human chess play over the internet. I was looking at some tutorials, to learn how to develop Android applications and found a very nice example of making galleries (it was a GridView usage example for making a gallery about dogs) and the idea came to draw the chess table using a GridView, because the example project also handled the point & click event and I intended to use the same event in the same way, but for a different purpose. The game works well (currently it's a hotseat version), however, I'm really frustrated by the fact that whenever I rotate the screen of the phone, my GridView gets hysterical and puts some empty space in my chess table between the columns. I realized that the cause of this is that the GridView's width is the same as its parent's and the GridView tries to fill its parent in with, but there should (and probably is) be a simple solution to get rid of this problem. However, after a full day of researching, I haven't found any clue to help me to make a perfect drawing about my chess table without a negative side effect in functionality. The chess table looks fine if the phone is in Portrait mode, but in Landscape mode it's far from nice. This is how I can decide whether we are in Portrait or Landscape mode: ((((MainActivity)mContext).getWindow().getWindowManager().getDefaultDisplay().getWidth()) < ((MainActivity)mContext).getWindow().getWindowManager().getDefaultDisplay().getHeight()) In the main.xml file the GridView is defined in the following way: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numColumns="8" android:verticalSpacing="0dp" android:horizontalSpacing="0dp" android:stretchMode="columnWidth" android:gravity="center" > </GridView> ... </LinearLayout> I appreciate any help with the problem and thank you for reading this.

  • Movies recommendation engine conceptual database design

    - by Supyxy
    I am working at an movie recommendations engine and i'm facing a DB design issue. My actual database looks like this: MOVIES [ID,TITLE] KEYWORDS_TABLE [ID,KEY_ID] - where ID is Foreign Key for MOVIES.id and KEY_ID is a key for a text keywords table This is not the entire DB, but i showed here what's important for my problem. I have about 50,000 movies and about 1,3 milion keywords correlations, and basically my algorithm consists in extracting all the who have the same keywords with a given movie, then ordering them by the number of keywords correlations. For example i looked for a movie similar to 'Cast away' and it returned 'Six days and six nights' because it had the most keywords correlations (4 keywords): Island Airplane crash Stranded Pilot The algorithm is based on more factors, but this one is the most important and the most difficult for the approach. Basically what i do now is getting all the movies that have at least one keyword similar to the given movie and then ordering them by other factors which are not important for a moment. There wouldn't be any problem if there weren't so many records, a query lasts in many cases up to 10-20 seconds and some of them return even over 5000 movies. Someone already helped me on here (thanks Mark Byers) with optimizing the query but that's not enough because it takes too longer SELECT DISTINCT M.title FROM keywords_table K1 JOIN keywords_table K2 ON K2.key_id = K1.key_id JOIN movies M ON K2.id = M.id WHERE K1.id = 4 So i thought it would be better if i pre-made those lists with movies recommendations for each movie, but i'm not sure how to design the tables.. whatever is it a good idea or how would you take this approach?

  • Vim step-by-step: How do you line up arbitrary text by arbitrary delimiter?

    - by dreftymac
    Background: There are a lot of great tutorials and "tricks" pages for Vim, but one thing that is very difficult is to find specific instructions on how to do some arbitrary thing that one can easily do in one's own familiar text editor IDE. Therefore I am asking for step by step instructions on how you I would do something in Vim that I already know how to do in other text editors. I like Vim and the great built-in help and numerous on-line tutorials, but sometimes a human has to break down and ask another human. Question: Suppose I have the following code in my file, how can I use Vim to get from BEFORE, to AFTER? BEFORE: Lorem ipsum dolor | sit amet, consectetur | adipisicing elit, sed do eiusmod | tempor incididunt | ut labore et | dolore magna aliqua. | Ut enim ad minim veniam, quis nostrud | exercitation ullamco | laboris nisi ut | aliquip ex ea commodo | consequat. Duis aute irure AFTER: Lorem ipsum dolor | sit amet, consectetur | adipisicing elit, sed do eiusmod | tempor incididunt | ut labore et | dolore magna aliqua. | Ut enim ad minim veniam, quis nostrud | exercitation ullamco | laboris nisi ut | aliquip ex ea commodo | consequat.

  • how to Compute the average probe length for success and failure - Linear probe (Hash Tables)

    - by fang_dejavu
    hi everyone, I'm doing an assignment for my Data Structures class. we were asked to to study linear probing with load factors of .1, .2 , .3, ...., and .9. The formula for testing is: The average probe length using linear probing is roughly Success-- ( 1 + 1/(1-L)**2)/2 or Failure-- (1+1(1-L))/2. we are required to find the theoretical using the formula above which I did(just plug the load factor in the formula), then we have to calculate the empirical (which I not quite sure how to do). here is the rest of the requirements **For each load factor, 10,000 randomly generated positive ints between 1 and 50000 (inclusive) will be inserted into a table of the "right" size, where "right" is strictly based upon the load factor you are testing. Repeats are allowed. Be sure that your formula for randomly generated ints is correct. There is a class called Random in java.util. USE it! After a table of the right (based upon L) size is loaded with 10,000 ints, do 100 searches of newly generated random ints from the range of 1 to 50000. Compute the average probe length for each of the two formulas and indicate the denominators used in each calculationSo, for example, each test for a .5 load would have a table of size approximately 20,000 (adjusted to be prime) and similarly each test for a .9 load would have a table of approximate size 10,000/.9 (again adjusted to be prime). The program should run displaying the various load factors tested, the average probe for each search (the two denominators used to compute the averages will add to 100), and the theoretical answers using the formula above. .** how do I calculate the empirical success?
