  • Eclipselink: Create objects from JOIN query

    - by Raven
    Hi, I have a SQL query SELECT * FROM Thing AS a JOIN Thing_Property AS b ON a.id=b.Thing_ID JOIN Property AS c ON b.properties_ID = c.id JOIN Item AS d ON c.item_ID = d.id ORDER BY a.name, d.name and I Eclipselink to create my object model with it. Here is the model: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end but I can not figure out, how to make Eclipselink create the model from that query. Can you help?

  • Update or Insert Row depending on whether row is present in Microsoft SQL Server 2005

    - by Srikanth
    Hi, I am passing a XML document as a input to a stored procedure in Microsoft SQL Server 2005. This is the sample XML being passed as input <Strategy StrategyID="0" TOStrategyID="8" ShutdownQtySell="1" ShutdownQtyBuy="1"> <ParameterRange ParameterSetID="6" ParameterRangeID="1" ParameterRangeFrom="0" ParameterRangeTo="20" ParameterAutoTakeOut="False"> </ParameterRange> <ParameterRange ParameterSetID="6" ParameterRangeID="4" ParameterRangeFrom="21" ParameterRangeTo="40" ParameterAutoTakeOut="False"> </ParameterRange> <ParameterRange ParameterSetID="6" ParameterRangeID="5" ParameterRangeFrom="41" ParameterRangeTo="60" ParameterAutoTakeOut="False"> </ParameterRange> <ParameterRange ParameterSetID="6" ParameterRangeID="6" ParameterRangeFrom="61" ParameterRangeTo="80" ParameterAutoTakeOut="False"> </ParameterRange> <ParameterRange ParameterSetID="6" ParameterRangeID="7" ParameterRangeFrom="81" ParameterRangeTo="100" ParameterAutoTakeOut="False"> </ParameterRange> </Strategy> I am able to retrieve the data using OpenXML functionality in SQL server I am using this to get the data corresponding to ParameterRange rows SELECT ParameterRangeID as iRangeID, ParameterSetID as iSetID, ParameterRangeFrom as fRangeFrom, ParameterRangeTo as fRangeTo, ParameterAutoTakeOut as bTakeoutEnabled FROM OPENXML(@idoc, '/Strategy/ParameterRange', 1) WITH (ParameterSetID int,ParameterRangeID int,ParameterRangeFrom float,ParameterRangeTo float,ParameterAutoTakeOut bit) Now, I need to insert/update these rows into a table TempRanges which has (iRangeID,iSetID) as the primary key. If there is a row with the primary key, I want to update it the latest values and If there is no row with that primary key, I need to insert into the table. How can I accomplish this inside the Stored Procedure ? Thanks, Sri

  • Issue 15: Oracle Exadata Marketing Campaigns

    - by rituchhibber
         PARTNER FOCUS Oracle ExadataMarketing Campaign Steve McNickleVP Europe, cVidya Steve McNickle is VP Europe for cVidya, an innovative provider of revenue intelligence solutions for telecom, media and entertainment service providers including AT&T, BT, Deutsche Telecom and Vodafone. The company's product portfolio helps operators and service providers maximise margins, improve customer experience and optimise ecosystem relationships through revenue assurance, fraud and security management, sales performance management, pricing analytics, and inter-carrier services. cVidya has partnered with Oracle for more than a decade. RESOURCES -- Oracle PartnerNetwork (OPN) Oracle Exastack Program Oracle Exastack Optimized Oracle Exastack Labs and Enablement Resources Oracle Engineered Systems Oracle Communications cVidya SUBSCRIBE FEEDBACK PREVIOUS ISSUES Are you ready for Oracle OpenWorld this October? -- -- Please could you tell us a little about cVidya's partnering history with Oracle, and expand on your Oracle Exastack accreditations? "cVidya was established just over ten years ago and we've had a strong relationship with Oracle almost since the very beginning. Through our Revenue Intelligence work with some of the world's largest service providers we collect tremendous amounts of information, amounting to billions of records per day. We help our clients to collect, store and analyse that data to ensure that their end customers are getting the best levels of service, are billed correctly, and are happy that they are on the correct price plan. We have been an Oracle Gold level partner for seven years, and crucially just two months ago we were also accredited as Oracle Exastack Optimized for MoneyMap, our core Revenue Assurance solution. Very soon we also expect to be Oracle Exastack Optimized DRMap, our Data Retention solution." What unique capabilities and customer benefits does Oracle Exastack add to your applications? "Oracle Exastack enables us to deliver radical benefits to our customers. A typical mobile operator in the UK might handle between 500 million and two billion call data record details daily. Each transaction needs to be validated, billed correctly and fraud checked. Because of the enormous volumes involved, our clients demand scalable infrastructure that allows them to efficiently acquire, store and process all that data within controlled cost, space and environmental constraints. We have proved that the Oracle Exadata system can process data up to seven times faster and load it as much as 20 times faster than other standard best-of-breed server approaches. With the Oracle Exadata Database Machine they can reduce their datacentre equipment from say, the six or seven cabinets that they needed in the past, down to just one. This dramatic simplification delivers incredible value to the customer by cutting down enormously on all of their significant cost, space, energy, cooling and maintenance overheads." "The Oracle Exastack Program has given our clients the ability to switch their focus from reactive to proactive. Traditionally they may have spent 80 percent of their day processing, and just 20 percent enabling end customers to see advanced analytics, and avoiding issues before they occur. With our solutions and Oracle Exadata they can now switch that balance around entirely, resulting not only in reduced revenue leakage, but a far higher focus on proactive leakage prevention. How has the Oracle Exastack Program transformed your customer business? "We can already see the impact. Oracle solutions allow our delivery teams to achieve successful deployments, happy customers and self-satisfaction, and the power of Oracle's Exa solutions is easy to measure in terms of their transformational ability. We gained our first sale into a major European telco by demonstrating the major performance gains that would transform their business. Clients can measure the ease of organisational change, the early prevention of business issues, the reduction in manpower required to provide protection and coverage across all their products and services, plus of course end customer satisfaction. If customers know that that service is provided accurately and that their bills are calculated correctly, then over time this satisfaction can be attributed to revenue intelligence and the underlying systems which provide it. Combine this with the further integration we have with the other layers of the Oracle stack, including the telecommunications offerings such as NCC, OCDM and BRM, and the result is even greater customer value—not to mention the increased speed to market and the reduced project risk." What does the Oracle Exastack community bring to cVidya, both in terms of general benefits, and also tangible new opportunities and partnerships? "A great deal. We have participated in the Oracle Exastack community heavily over the past year, and have had lots of meetings with Oracle and our peers around the globe. It brings us into contact with like-minded, innovative partners, who like us are not happy to just stand still and want to take fresh technology to their customer base in order to gain enhanced value. We identified three new partnerships in each of two recent meetings, and hope these will open up new opportunities, not only in areas that exactly match where we operate today, but also in some new associative areas that will expand our reach into new business sectors. Notably, thanks to the Exastack community we were invited on stage at last year's Oracle OpenWorld conference. Appearing so publically with Oracle senior VP Judson Althoff elevated awareness and visibility of cVidya and has enabled us to participate in a number of other events with Oracle over the past eight months. We've been involved in speaking opportunities, forums and exhibitions, providing us with invaluable opportunities that we wouldn't otherwise have got close to." How has Exastack differentiated cVidya as an ISV, and helped you to evolve your business to the next level? "When we are selling to our core customer base of Tier 1 telecommunications providers, we know that they want more than just software. They want an enduring partnership that will last many years, they want innovation, and a forward thinking partner who knows how to guide them on where they need to be to meet market demand three, five or seven years down the line. Membership of respected global bodies, such as the Telemanagement Forum enables us to lead standard adherence in our area of business, giving us a lot of credibility, but Oracle is also involved in this forum with its own telecommunications portfolio, strengthening our position still further. When we approach CEOs, CTOs and CIOs at the very largest Tier 1 operators, not only can we easily show them that our technology is fantastic, we can also talk about our strong partnership with Oracle, and our joint embracing of today's standards and tomorrow's innovation." Where would you like cVidya to be in one year's time? "We want to get all of our relevant products Oracle Exastack Optimized. Our MoneyMap Revenue Assurance solution is already Exastack Optimised, our DRMAP Data Retention Solution should be Exastack Optimised within the next month, and our FraudView Fraud Management solution within the next two to three months. We'd then like to extend our Oracle accreditation out to include other members of the Oracle Engineered Systems family. We are moving into the 'Big Data' space, and so we're obviously very keen to work closely with Oracle to conduct pilots, map new technologies onto Oracle Big Data platforms, and embrace and measure the benefits of other Oracle systems, namely Oracle Exalogic Elastic Cloud, the Oracle Exalytics In-Memory Machine and the Oracle SPARC SuperCluster. We would also like to examine how the Oracle Database Appliance might benefit our Tier 2 service provider customers. Finally, we'd also like to continue working with the Oracle Communications Global Business Unit (CGBU), furthering our integration with Oracle billing products so that we are able to quickly deploy fraud solutions into Oracle's Engineered System stack, give operational benefits to our clients that are pre-integrated, more cost-effective, and can be rapidly deployed rapidly and producing benefits in three months, not nine months." Chris Baker ,Senior Vice President, Oracle Worldwide ISV-OEM-Java Sales Chris Baker is the Global Head of ISV/OEM Sales responsible for working with ISV/OEM partners to maximise Oracle's business through those partners, whilst maximising those partners' business to their end users. Chris works with partners, customers, innovators, investors and employees to develop innovative business solutions using Oracle products, services and skills. Firstly, could you please explain Oracle's current strategy for ISV partners, globally and in EMEA? "Oracle customers use independent software vendor (ISV) applications to run their businesses. They use them to generate revenue and to fulfil obligations to their own customers. Our strategy is very straight-forward. We want all of our ISV partners and OEMs to concentrate on the things that they do the best – building applications to meet the unique industry and functional requirements of their customer. We want to ensure that we deliver a best in class application platform so the ISV is free to concentrate their effort on their application functionality and user experience We invest over four billion dollars in research and development every year, and we want our ISVs to benefit from all of that investment in operating systems, virtualisation, databases, middleware, engineered systems, and other hardware. By doing this, we help them to reduce their costs, gain more consistency and agility for quicker implementations, and also rapidly differentiate themselves from other application vendors. It's all about simplification because we believe that around 25 to 30 percent of the development costs incurred by many ISVs are caused by customising infrastructure and have nothing to do with their applications. Our strategy is to enable our ISV partners to standardise their application platform using engineered architecture, so they can write once to the Oracle stack and deploy seamlessly in the cloud, on-premise, or in hybrid deployments. It's really important that architecture is the same in order to keep cost and time overheads at a minimum, so we provide standardisation and an environment that enables our ISVs to concentrate on the core business that makes them the most money and brings them success." How do you believe this strategy is helping the ISVs to work hand-in-hand with Oracle to ensure that end customers get the industry-leading solutions that they need? "We work with our ISVs not just to help them be successful, but also to help them market themselves. We have something called the 'Oracle Exastack Ready Program', which enables ISVs to publicise themselves as 'Ready' to run the core software platforms that run on Oracle's engineered systems including Exadata and Exalogic. So, for example, they can become 'Database Ready' which means that they use the latest version of Oracle Database and therefore can run their application without modification on Exadata or the Oracle Database Appliance. Alternatively, they can become WebLogic Ready, Oracle Linux Ready and Oracle Solaris Ready which means they run on the latest release and therefore can run their application, with no new porting work, on Oracle Exalogic. Those 'Ready' logos are important in helping ISVs advertise to their customers that they are using the latest technologies which have been fully tested. We now also have Exadata Ready and Exalogic Ready programmes which allow ISVs to promote the certification of their applications on these platforms. This highlights these partners to Oracle customers as having solutions that run fluently on the Oracle Exadata Database Machine, the Oracle Exalogic Elastic Cloud or one of our other engineered systems. This makes it easy for customers to identify solutions and provides ISVs with an avenue to connect with Oracle customers who are rapidly adopting engineered systems. We have also taken this programme to the next level in the shape of 'Oracle Exastack Optimized' for partners whose applications run best on the Oracle stack and have invested the time to fully optimise application performance. We ensure that Exastack Optimized partner status is promoted and supported by press releases, and we help our ISVs go to market and differentiate themselves through the use our technology and the standardisation it delivers. To date we have had several hundred organisations successfully work through our Exastack Optimized programme." How does Oracle's strategy of offering pre-integrated open platform software and hardware allow ISVs to bring their products to market more quickly? "One of the problems for many ISVs is that they have to think very carefully about the technology on which their solutions will be deployed, particularly in the cloud or hosted environments. They have to think hard about how they secure these environments, whether the concern is, for example, middleware, identity management, or securing personal data. If they don't use the technology that we build-in to our products to help them to fulfil these roles, they then have to build it themselves. This takes time, requires testing, and must be maintained. By taking advantage of our technology, partners will now know that they have a standard platform. They will know that they can confidently talk about implementation being the same every time they do it. Very large ISV applications could once take a year or two to be implemented at an on-premise environment. But it wasn't just the configuration of the application that took the time, it was actually the infrastructure - the different hardware configurations, operating systems and configurations of databases and middleware. Now we strongly believe that it's all about standardisation and repeatability. It's about making sure that our partners can do it once and are then able to roll it out many different times using standard componentry." What actions would you recommend for existing ISV partners that are looking to do more business with Oracle and its customer base, not only to maximise benefits, but also to maximise partner relationships? "My team, around the world and in the EMEA region, is available and ready to talk to any of our ISVs and to explore the possibilities together. We run programmes like 'Excite' and 'Insight' to help us to understand how we can help ISVs with architecture and widen their environments. But we also want to work with, and look at, new opportunities - for example, the Machine-to-Machine (M2M) market or 'The Internet of Things'. Over the next few years, many millions, indeed billions of devices will be collecting massive amounts of data and communicating it back to the central systems where ISVs will be running their applications. The only way that our partners will be able to provide a single vendor 'end-to-end' solution is to use Oracle integrated systems at the back end and Java on the 'smart' devices collecting the data – a complete solution from device to data centre. So there are huge opportunities to work closely with our ISVs, using Oracle's complete M2M platform, to provide the infrastructure that enables them to extract maximum value from the data collected. If any partners don't know where to start or who to contact, then they can contact me directly at [email protected] or indeed any of our teams across the EMEA region. We want to work with ISVs to help them to be as successful as they possibly can through simplification and speed to market, and we also want all of the top ISVs in the world based on Oracle." What opportunities are immediately opened to new ISV partners joining the OPN? "As you know OPN is very, very important. New members will discover a huge amount of content that instantly becomes accessible to them. They can access a wealth of no-cost training and enablement materials to build their expertise in Oracle technology. They can download Oracle software and use it for development projects. They can help themselves become more competent by becoming part of a true community and uncovering new opportunities by working with Oracle and their peers in the Oracle Partner Network. As well as publishing massive amounts of information on OPN, we also hold our global Oracle OpenWorld event, at which partners play a huge role. This takes place at the end of September and the beginning of October in San Francisco. Attending ISV partners have an unrivalled opportunity to contribute to elements such as the OpenWorld / OPN Exchange, at which they can talk to other partners and really begin thinking about how they can move their businesses on and play key roles in a very large ecosystem which revolves around technology and standardisation." Finally, are there any other messages that you would like to share with the Oracle ISV community? "The crucial message that I always like to reinforce is architecture, architecture and architecture! The key opportunities that ISVs have today revolve around standardising their architectures so that they can confidently think: “I will I be able to do exactly the same thing whenever a customer is looking to deploy on-premise, hosted or in the cloud”. The right architecture is critical to being competitive and to really start changing the game. We want to help our ISV partners to do just that; to establish standard architecture and to seize the opportunities it opens up for them. New market opportunities like M2M are enormous - just look at how many devices are all around you right now. We can help our partners to interface with these devices more effectively while thinking about their entire ecosystem, rather than just the piece that they have traditionally focused upon. With standardised architecture, we can help people dramatically improve their speed, reach, agility and delivery of enhanced customer satisfaction and value all the way from the Java side to their centralised systems. All Oracle ISV partners must take advantage of these opportunities, which is why Oracle will continue to invest in and support them." -- Gergely Strbik is Oracle Hardware and Software Product Manager for Avnet in Hungary. Avnet Technology Solutions is an OracleValue Added Distributor focused on the development of the existing Oracle channel. This includes the recruitment and enablement of Oracle partners as well as driving deeper adoption of Oracle's technology and application products within the IT channel. "The main business benefits of ODA for our customers and partners are scalability, flexibility, a great price point for the high performance delivered, and the easily configurable embedded Linux operating system. People welcome a lower point of entry and the ability to grow capacity on demand as their business expands." "Marketing and selling the ODA requires another way of thinking because it is an appliance. We have to transform the ways in which our partners and customers think from buying hardware and software independently to buying complete solutions. Successful early adopters and satisfied customer reactions will certainly help us to sell the ODA. We will have more experience with the product after the first deliveries and installations—end users need to see the power and benefits for themselves." "Our typical ODA customers will be those looking for complete solutions from a single reseller partner who is also able to manage the appliance. They will have enjoyed using Oracle Database but now want a new product that is able to unlock new levels of performance. A higher proportion of potential customers will come from our existing Oracle base, with around 30% from new business, but we intend to evangelise the ODA on the market to see how we can change this balance as all our customers adjust to the concept of 'Hardware and Software, Engineered to Work Together'. -- Back to the welcome page

    I am not a Linux admin, although I wish I was, and I have seen these questions Amazon EC2 Backup Strategy Amazon EC2 + EBS:: Regular backup plan? Simple Backup Strategy for Amazon EC2 instances / volumes? And this suggestion http://alestic.com/2009/09/ec2-consistent-snapshot I tried using command line + crontab (the command line works, but crontab for some reason, doesn't) But I'm still pretty lost, all I want is an automated, rolling backup of my amazon EC2 (EBS) data (by rolling I mean keep 3-4 weeks back, but delete old snapshots as new ones come for cost control) And as things usually go, if there is something that is hard and painful, someone creates a solution for it. My question is simple, is there a way using a tool like Puppet to do it without a painful learning curve? (or via other tools like http://ylastic.com) If yes, how?

  • Symantec Backup exec 2012 for SBS - moving data to offsite drives

    - by Will Lennard
    Can anyone advise how best to run the following strategy, or even if it is possible/sensible strategy? I am looking to backup an SBS server using BE2012 where the data is backed up on a weekly full backup, with subsequent daily incrementals till the end of the week, a fresh full backup will then be taken the next weekend, and the cycle repeats for 4 weeks, thus 4 full backups with incrementals. This months worth of backups will then be moved off to an offsite store via USB drive for safe keeping. Is this viable, sensible, or am i just a bit crazy? All ideas are welcome.

  • On improving commit practices

    - by greengit
    I was thinking about ways to improving my commit practices. Is there any co-relation between no. of source code lines and no. of commits? In a recent project that I was involved in, I was going at 30 commits per 1000 lines. One typical file from the project has these stats language: JavaScript total commits that include this file: 32 total lines: 1408 source lines: 1140 comment lines: 98 no. of function declarations: 28 other declarations: 8 Another file has these... Language: Python total commits that include this file: 17 total lines: 933 source lines: 730 comment lines: 80 classes: 1 methods: 10 I also think that no. of commits is more related to no. of features or no. of changes to the code and less to the no. of lines. The general git community motto is make short commits and commit often. So, do you really think about you commit strategy before you start the project. For that matter, is there anything like commit strategy? If so, what's yours?

  • Turning a board game idea into a browser based, slow paced gameplay

    - by guillaume31
    Suppose I want to create a strategy game with global mutable state shared between all players (think game board). But unlike a board game, I don't want it to be real time action and/or turn-based. Instead, players should be able to log in at any time of the day and spend a fixed number of action points per day as they wish. As opposed to a few hours, game sessions would run over a few weeks. This is meant to reward good strategy rather than time spent playing (as an alternative, hardcore players could always play multiple games in parallel instead) as well as all kind of issues related to live playing like disconnections and synchronization. The game should remain addictive still have a low time investment footprint for casual players. So far so good, but this still leaves open the question of when to solve actions and when they should be visible. I want to avoid "ninja play" like doing all your moves just a few minutes before daily point reset to take other players by surprise, or people spamming F5 to place a well-timed action which would defeat the whole point of a non real-time game. I thought of a couple of approaches to that : Resolve all events in a single scheduled process running once a day. This basically means a "blind" gameplay where players can take actions but don't see their results immediately. The thing is, I played a similar browser game a few years ago and didn't like the fact that you feel disconnected and powerless until there's that deus ex machina telling you what really happened during all that time. You see the world evolve in large increments of one day, which often doesn't seem like seeing it evolve at all. For actions that have an big impact on the game or on other players (attacks, big achievements), make them visible to everyone immediately but delay their effect by something like 24 hours. Opposing players could be notified when such an event happens, so that they can react to it. Do you have any other ideas how I could go about solving this ? Are there any known approaches in similar existing games ?

  • Step Aside Google

    - by David Dorf
    Step aside Google. While search will always be a huge part of the web, I can see a day in the not-too-distance future where search takes a backseat to the social graph. Links between pages will give way to relationships between people, including context like location. What does this mean for retail? It means your e-commerce strategy will slowly transition to an f-commerce strategy. Remember when a large portion of the online population was held captive inside the walls of AOL? All the commercials listed an AOL keyword, not a web address because that's where the majority of people surfed. Now, people are spending a huge amount of time in Facebook (despite Betty White's proclamation that its a big waste of time). According to Facebook, users spend 500 billion minutes per month on the site. Selling products where consumers are spending their time makes sense. The power of Like and Share are the most effective approach to marketing. More and more stores are popping up on Facebook, and soon they will be the front-end to e-commerce systems. As sites adopt the Facebook Open Graph API, users will have a harder time distinguishing the open web from their Facebook experience, including shopping. Of course e-commerce sites won't go away, but a large portion of their traffic will emanate from Facebook and in some cases Facebook will act as the front-end for the web store. Ignore Facebook Open Graph at your peril. In a Mashable article, Mitchell Harper made several predictions about how e-commerce will change based on Facebook. His five points are not far-fetched at all, so we need to watch this space carefully.

  • Oracle Social Network -The Social Glue for Enterprise Applications

    - by kellsey.ruppel
    by Peter Reiser  - Social Business Evangelist, Oracle WebCenter  Tom Petrocelli of Enterprise Strategy Group published a report recently, “Oracle Social Network: The Social Glue for Enterprise Applications”, on Oracle Social Network (OSN) and how traditional social products create social silos whereas OSN is the “social glue” for enterprise applications.  This report supports the point of Oracle’s Social Business Strategy to seamless integrate social capabilities into the main business processes. Quote from report: “Oracle has adopted the correct approach to creating a social layer and socially enabled applications. Oracle Social Network is not simply another enterprise social network product; it is a complete social layer for the enterprise application stack. This approach will serve Oracle users well in the future.” OSN allow to capture the related Conversations of a business process right where it’s happens – within the respective Business application.  Fusion CRM is an excellent example for this approach. Quote from report: “Oracle’s new software, Oracle Social Network, is an example of a solution to the silo problem. While Oracle fields a typical enterprise social network application with microblogging, file sharing, shared documents or wikis, and activity streams, the front-end application is only a small part of what Oracle Social Network does. Instead, Oracle Social Network is a platform that provides social features as a service to other enterprise applications. In effect, Oracle Social Network socially enables all of Oracle’s enterprise applications—all enterprise applications really—with not only the same features, but also the same conversations. As a result, the social conversations act as a conduit for inter-application communication and collaboration.” Source: ESG Research Report, Oracle Social Network: The Social Glue for Enterprise Applications, August 2012.

  • eBay Leads Mobile Commerce

    - by David Dorf
    For the first time, more smartphones where shipped than PCs. This important milestone helps reinforce that retailers need a strong mobile commerce strategy. IDC reported that for the 4th quarter of 2010, manufacturers shipped 100.9 million devices versus 92.1 million PCs shipped. One early adopter for the retail industry is eBay, the popular online auction and shopping site. In July 2008 they released their first mobile app and have increased investments ever since. In 2002 they bought PayPal for use with its online channel, but its becoming a force in the mobile world as well. In June 2010 they acquired RedLaser, the popular barcode scanning mobile app. Both pieces of technology enhance the mobile experience, and are available to other retailers as well. More recently, in December 2010 they acquired Critical Path Software, the developer of their eBay, StubHub, and Shopping.com mobile applications. Taking their mobile development in-house was a clear signal that mobile commerce is important to their strategy. Pop on over the eBay Inc's mobile commerce stats page to see just how well they are doing. You can use the animated map to see where people are using the app on any given day, and you can compare sales of the different categories. eBay's hottest category is Cars & Trucks, garnering 16.5% of the total $2B (yes, billion) in mobile sales in 2010. To understand why that category is so large, let's look at the top 10 most expensive cars sold on eBay mobile in 2010: $240,001 Mercedes-Benz: SLR McLaren $209,888 Lamborghini: Gallardo $208,500 Ferrari: 430 $199,900 Lamborghini: Gallardo $189,000 Lamborghini: Murcielago $185,000 Ferrari: 430 $175,000 Porsche: 911 $170,000 Ferrari: 550 $160,000 Bentley: Continental, GT $159,900 Lamborghini: Gallardo eBay claims they sell 3-4 Ferraris on their mobile app each month. Yes, mobile commerce is not limited to small items. While I would wait to get home and fire up the PC, the current generation that has grown up with mobile phones has no issue satisfying their impulses. Dave Sikora of Digby told me he's seen people buy furniture sets, mattresses, and diamonds via their mobile phones. I guess mobile commerce is rapidly becoming the norm.

  • New Year's Resolutions and Keeping in Touch in 2011

    - by Brian Dayton
    The run-up to Oracle OpenWorld 2010 San Francisco--and the launch of Fusion Applications--was a busy time for many of us working on the applications business at Oracle. The great news was that the Oracle Applications general sessions, sessions, demogrounds and other programs were very well attended and well received. Unfortunately, for this blog, the work wasn't done there. Yes, there haven't been many additional blog entries since the previous one, which one industry analyst told us "That's a good post!" That being said, our New Year's Resolution is to blog more frequently about what's been keeping us busy since Oracle OpenWorld San Francisco. A quick summary: - A 4-part webcast series covering major elements of Oracle's Applications strategy - Oracle OpenWorld Brazil - Oracle OpenWorld China - A stellar fiscal Q2 for Oracle and our applications business - Engagement with many Oracle Fusion Applications Early Adopter customers (more on this in the coming year) Objectives for the Coming Year Looking forward at 2011 there are many ways in which we hope to continue making connections with our valued customers and partners, sharing information about where Oracle Applications are headed, and answering questions about how to manage your Oracle Applications roadmap. Things to look for in 2011: - Stay connected with Oracle Applications on a daily basis via our Facebook page. You don't have to be a member of Facebook---but if you are and "like" the page you'll have daily insights and updates delivered to your account http://www.facebook.com/OracleApps - Coming soon, an Oracle Applications strategy update World Tour---a global program that takes key updates and information to cities around the globe - Save the date: On February 3rd, Oracle will be hosting a global, online conference for Oracle Applications customers, partners and interested parties Happy New Year and look for us in 2011.

    - by Richard Lefebvre
    The 2012 edition of the Oracle EMEA Cloud Partner Community Forum took place on march 28&29 in Madrid. 100 participants from all over Europe had a chance to interact with the Oracle Cloud CRM Product Management team about multiple subjects such as Oracle Cloud CRM and Social Network solutions strategy, RightNow acquisition, Fusion CRM Business opportunities for partners, etc. During his opening keynote, Anthony Lye (Oracle Senior Vice-President and head of Oracle CRM) presented the current Fusion CRM business status, disclosed the overall Oracle CRM product strategy and responded to many questions from the audience. Later on that day, 8 Oracle ISV's presented their Oracle Cloud CRM add-on's and highlighted the value that System Integrators can benefit from as part of a Cloud CRM project. After a very friendly networking diner in a Spanish restaurant, the second day was dedicated to Fusion CRM, with a deeper dive into its major components (Sales, Sales Planning, Marketing) including the Fusion Composers. Briefings on Oracle Consulting Services Fusion CRM dedicated offerings and Fusion CRM Partner Programs concluded the day and the event. All participants rated the event as "good" to "Excellent" and mentioned that it was meaningful for them to plan their Oracle Cloud CRM based business in the near future.
