  • Visual Studio LightSwitch: Yes, these are the droids you&rsquo;re looking for

    - by Jim Duffy
    With all the news and focus on the new features coming in Silverlight 5 I thought I’d take a few minutes to remind folks about the work that Microsoft has done on LightSwitch since the applications created by LightSwitch are Silverlight applications. LightSwitch makes it easier for non-coders to build business applications and easier for coders to maintain them. For those not familiar with LightSwitch, it is a new tool that provides a easier and quicker way for coder and non-coder types alike to create line-of-business applications for the desktop, the web, and the cloud. The target audience for this tool are those power-user types who create Access applications for their organization. While those Access applications fill an immediate need, they typically aren’t very scalable, extendable and/or maintainable by the development staff of the organization. LightSwitch creates applications based on technologies built into Visual Studio thus making it easier for corporate developers to extend and maintain them. LightSwitch is currently in beta but it will ultimately become a new addition to the Visual Studio line of products. Go ahead and download the beta to get a better idea of what the product can do for your organization. The LightSwitch Developer Center contains links to download the beta links to instructional videos links to tutorials links to the LightSwitch Training Kit Another quality resource for LightSwitch information is the Visual Studio LightSwitch Team Blog. My good friend Beth Massi is on the LightSwitch team and has additional valuable content on her blog. Have a day.

  • Ideas for my MSc project and Google Summer of Code 2011

    - by Chris Wilson
    I'm currently putting together ideas for my master's project which I'll be working on over the summer, and I would like to be able to use this time to help Ubuntu in some way. I have the freedom to come up with pretty much any project in the field of software development/engineering provided it Is a substantial piece of software (for reference, I will be working on it for five full months) Solves a problem for more people than just myself I was hoping to use this project as an opportunity to get some experience with the underbelly of Linux, so that I can mention on my CV that I have 'experience in developing for *NIX in C++', which I'm noticing more and more companies are looking for these days, probably because stuff's moving to cloud servers and that's where Linux rules the roost. My problem is that, since I don't have the experience to begin with, I'm not sure what to do for such a project, and I was wondering if anyone could help me with this. I've noticed from Daniel Holbach's blog that Ubuntu participated in the Google Summer of Code 2010, and that project ideas for that can be found here. However, I have not been able to find anything related to Ubuntu and GSoC 2011, but I have noticed from the GSoC timeline that the list of mentoring organisations will not be published until March 18th. I have two questions here. Has Ubuntu applied to be a part of Summer of Code 2011, and what is the status of the 2010 project list linked to earlier. Were they all implemented or are there still some that can be picked up now, should I not participate in GSoC? I'd like to do something for Ubuntu, but I'd rather not spend my time reinventing the wheel.

  • Auto-cancel reason not found (6, 13906)

    - by Rajesh Sharma
    There are many errors in the application which are never invoked because of appropriate application configuration done at the time of implementation by the solution architects. So typically, as an application end user you would never stumble upon such errors. But what if the application administrator inadvertently changes the configuration/setup in the development, test, QA, or production environment? This is the time when you as an end user are introduced to a brand-new error for which you may not have a clue or understanding to what it means and neither the access/privilege to rectify it.    In this post we'll focus on one such error '6, 13906 - Auto-cancel reason not found'.   You get this error if you have not defined a Bill (Segment) Cancel Reason (Admin Menu, B, Bill Cancel Reason) code with System Default value of Turn off auto-cancel.   Consider a scenario when you are about to final bill an 'Account' for which the bill period's cut-off date you selected is falling on or after the Service Agreement's (SA) end/stop date (basically SA is Stopped with a date earlier than it was billed previously). And for the same 'Account' either: Bill segments exists that end after the SA's end date OR Non-closing bill segments exists that end on the SA's end date (OR closing bill segments that do not end on SA's end date or do not exist at all - remember closing/final bill segment is generated if the SA is in Stopped status).   CC&B detects such scenario and attempts to cancel all such violating bill segments automatically, but NOT if you are generating the bill Online. If online, the system assumes that you know what you are doing, and prompts you with error 2, 13716 - Bill segments that violate the SA (%1) End Date (%2) exist to take necessary action.   If in batch, system automatically cancels these kinds of bill segment(s).   Since this happens in the background, you have to define within the application which System Default Bill (Segment) cancellation reason code identified as Turn off auto-cancel, should be used by the process when it attempts to cancel any such violating bill segments (You already know that you cannot cancel a bill segment without giving a reason for cancellation).   So what exactly happens during batch billing?   Bill Segment generation routine at first determines billing eligibility of the service agreement being billed. One of the billing eligibility criteria is to check the SA's previous bill segments which have end dates greater than the current cut-off date/end date. Technically, the routine retrieves a count of such violating bill segments.     SELECT COUNT (*) FROM CI_BSEG WHERE SA_ID = :SA-ID AND BSEG_STAT_FLG = '50' -- Frozen AND END_DT IS NOT NULL AND (END_DT > '03-JUN-2010' -- Bill segment greater than SA's End Date OR OR (END_DT = '03-JUN-2010' AND CLOSING_BSEG_SW = 'N')) -- Non-closing bill segment ending on SA's end date   If the count is greater than zero, Bill segment generation routine executes another program to auto-cancel such bill segments. Auto-cancel program retrieves the 'Bill Cancel Reason' code which is identified as Turn off auto-cancel. Retrieved cancel reason code is then placed on the bill segments that are being cancelled automatically.   During this process if the routine fails to determine the bill cancel reason code having System Default Turn off auto-cancel because it was not been configured, you get a bill exception 6, 13906 - Auto-cancel reason not found.   Also note that duplicate or multiple System Default codes identified as Turn off auto-cancel are not allowed. CC&B would complain with an error 2, 54201.   Duplicate validation/check is also performed within Auto-cancel routine, if suppose for test purposes you executed a DML statement updating CI_BILL_CAN_RSN.BSCAN_SYS_DFLT_FLG with a value 'T'.

  • Dude, what’s up with POP Forums vNext?

    - by Jeff
    Yeah, it has been awhile. I posted v9.2 back in January, about five months ago. That’s a real change from the release pace I had there for awhile. Let me explain what’s going on. First off, in the interim, I re-launched CoasterBuzz, which required a lot of my attention for about two of those months. That’s a good thing though, because that site is just about the best test bed I could ask for. The other thing is that I committed to make the next version use ASP.NET MVC 4, which is now at the RC stage. I didn’t think much about when they’d hit their RTW point, but RC is good enough for me. To that end, there is enough change in the next version that I recently decided to make it a major version upgrade, and finish up the loose ends and science projects to make it whole. Here’s what’s in store… Mobile views: I sat on this or a long time. Originally, I was going to use jQuery Mobile, and waited and waited for a new release, but in the end, decided against using it. Sometimes buttons would unexplainably not work, I felt like I was fighting it at times, and the CSS just felt too heavy. I rolled my own mobile sugar at a fraction of the size, and I think you’ll find it easy to modify. And it’s Metro-y, of course! Re-do of background services: A number of things run in the background, and I did quite a bit of “reimagining” of that code. It’s the weirdness of running services in a Web site context, because so many folks can’t run a bona fide service on their host’s box. The biggest change here is that these service no longer start up by default. You’ll need to call a new method from global.asax called PopForumsActivation.StartServices(). This is also a precursor to running the app in a Web farm (new data layer and caching is the second part of that). I learned about this the hard way when I had three apps using the forum library code but only one was actually the forum. The services were all running three times as often with race conditions and hits on the same data. That was particularly bad for e-mail. CSS clean up: It’s still not ideal, but it’s getting better. That’s one of those things that comes with integrating to a real site… you discover all of the dumb things you did. The mobile CSS is particularly easier to live with. Bug fixes: There are a whole lot of them. Most were minor, but it’s feeling pretty solid now. So that’s where I am. I’m going to call it v10.0, and I’m going to really put forth some effort toward finishing the mobile experience and getting through the remaining bugs. The roadmap beyond that will likely not be feature oriented, but rather work on some other things, like making it run in Azure, perhaps using SQL CE, a better install experience, etc. As usual, I’ll post the latest here. Stay tuned!

  • .NET 4.5 now supported with Windows Azure Web Sites

    - by ScottGu
    This week we finished rolling out .NET 4.5 to all of our Windows Azure Web Site clusters.  This means that you can now publish and run ASP.NET 4.5 based apps, and use  .NET 4.5 libraries and features (for example: async and the new spatial data-type support in EF), with Windows Azure Web Sites.  This enables a ton of really great capabilities - check out Scott Hanselman’s great post of videos that highlight a few of them. Visual Studio 2012 includes built-in publishing support to Windows Azure, which makes it really easy to publish and deploy .NET 4.5 based sites within Visual Studio (you can deploy both apps + databases).  With the Migrations feature of EF Code First you can also do incremental database schema updates as part of publishing (which enables a really slick automated deployment workflow). Each Windows Azure account is eligible to host 10 free web-sites using our free-tier.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using them today. In the next few days we’ll also be releasing support for .NET 4.5 and Windows Server 2012 with Windows Azure Cloud Services (Web and Worker Roles) – together with some great new Azure SDK enhancements.  Keep an eye out on my blog for details about these soon. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Oracle Fusion Procurement Designed for User Productivity

    - by Applications User Experience
    Sean Rice, Manager, Applications User Experience Oracle Fusion Procurement Design Goals In Oracle Fusion Procurement, we set out to create a streamlined user experience based on the way users do their jobs. Oracle has spent hundreds of hours with customers to get to the heart of what users need to do their jobs. By designing a procurement application around user needs, Oracle has crafted a user experience that puts the tools that people need at their fingertips. In Oracle Fusion Procurement, the user experience is designed to provide the user with information that will drive navigation rather than requiring the user to find information. One of our design goals for Oracle Fusion Procurement was to reduce the number of screens and clicks that a user must go through to complete frequently performed tasks. The requisition process in Oracle Fusion Procurement (Figure 1) illustrates how we have streamlined workflows. Oracle Fusion Self-Service Procurement brings together billing metrics, descriptions of the order, justification for the order, a breakdown of the components of the order, and the amount—all in one place. Previous generations of procurement software required the user to navigate to several different pages to gather all of this information. With Oracle Fusion, everything is presented on one page. The result is that users can complete their tasks in less time. The focus is on completing the work, not finding the work. Figure 1. Creating a requisition in Oracle Fusion Self-Service Procurement is a consumer-like shopping experience. Will Oracle Fusion Procurement Increase Productivity? To answer this question, Oracle sought to model how two experts working head to head—one in an existing enterprise application and another in Oracle Fusion Procurement—would perform the same task. We compared Oracle Fusion designs to corresponding existing applications using the keystroke-level modeling (KLM) method. This method is based on years of research at universities such as Carnegie Mellon and research labs like Xerox Palo Alto Research Center. The KLM method breaks tasks into a sequence of operations and uses standardized models to evaluate all of the physical and cognitive actions that a person must take to complete a task: what a user would have to click, how long each click would take (not only the physical action of the click or typing of a letter, but also how long someone would have to think about the page when taking the action), and user interface changes that result from the click. By applying standard time estimates for all of the operators in the task, an estimate of the overall task time is calculated. Task times from the model enable researchers to predict end-user productivity. For the study, we focused on modeling procurement business process task flows that were considered business or mission critical: high-frequency tasks and high-value tasks. The designs evaluated encompassed tasks that are currently performed by employees, professional buyers, suppliers, and sourcing professionals in advanced procurement applications. For each of these flows, we created detailed task scenarios that provided the context for each task, conducted task walk-throughs in both the Oracle Fusion design and the existing application, analyzed and documented the steps and actions required to complete each task, and applied standard time estimates to the operators in each task to estimate overall task completion times. The Results The KLM method predicted that the Oracle Fusion Procurement designs would result in productivity gains in each task, ranging from 13 percent to 38 percent, with an overall productivity gain of 22.5 percent. These performance gains can be attributed to a reduction in the number of clicks and screens needed to complete the tasks. For example, creating a requisition in Oracle Fusion Procurement takes a user through only two screens, while ordering the same item in a previous version requires six screens to complete the task. Modeling user productivity has resulted not only in advances in Oracle Fusion applications, but also in advances in other areas. We leveraged lessons learned from the KLM studies to establish products like Oracle E-Business Suite (EBS). New user experience features in EBS 12.1.3, such as navigational improvements to the main menu, a Google-type search using auto-suggest, embedded analytics, and an in-context list of values tool help to reduce clicks and improve efficiency. For more information about KLM, refer to the Measuring User Productivity blog.

  • Challenges and Opportunities to Drive Change in the Healthcare System Explored at America’s Health Insurance Plans Exchange Conference and Institute 2013

    - by elaine blog
    The program theme at the June America’s Health Insurance Plans (AHIP) Exchange Conference and AHIP’s Institute 2013 was Transforming Our Health Care System: Navigating and Succeeding in the New Marketplace.  Topics included care delivery transformation, innovation for a new healthcare eco system, Health Insurance Exchanges, the nexus of consumerism, retail and healthcare, driving value through improved operations and leveraging technology, data and innovation to transform care. Oracle participated as a sponsor of both conferences, signaling the significant investment and activity Oracle continues to make in helping health plans, providers and government agencies become more efficient and more relevant in the healthcare market place. AHIP is a national trade association representing the health insurance industry. AHIP’s members provide health and supplemental benefits to more than 200 million Americans through employer-sponsored coverage, the individual insurance market and public programs such as Medicare and Medicaid.   AHIP advocates for public policies that expand access to affordable health care. Health plans are focusing on the Health Insurance Exchanges and the opportunities they offer to provide better access and higher quality healthcare.  With the opportunities come operational challenges to implementation and innovative technology solutions to consider.   At the Exchange Conference, Oracle hosted a breakfast symposium on “Strategies for Success:  Driving Business Transformation in the Growing Health Insurance Exchange Market”. With Health Insurance Exchanges as catalysts for change, attendees learned about how to achieve integration within an Exchange and deploy new business strategies to support health reform initiatives. Discussion covered steps and processes to successfully establish and implement enrollment systems, quote to card activities, program pricing, claims billing, automated claims processing and new customer service tools. Piyush Pushkar, COO of Benefitalign, an Oracle partner that provides solutions to adopt innovative business models for retail, HIX, consumer-centric health plan and benefits administration, spoke on the state of the Exchanges in the U.S. and the activities health plans are engaged in to support individuals entering the healthcare system, including sales automation, member enrollment automation/portals and integration strategies with the Exchanges. The Oracle and Benefitalign partnership allows seamless integration between a health plan enrollment solution with the HIX individual market and allows for the health plan to customize and characterize the offerings available to the HIX that may or may not be available through other channels.  This approach can benefit the health plan through separation of interests, but also because some state-run HIXs require such separation. Janice W. Young, Program Director, Payer IT Strategies, IDC Health Insights, reviewed a survey of health plans on their investment priorities for this last year as well as this year.  She also identified the 2013-2015 strategies of go/get to market with front end and compliance investments; leveraging existing business processes and internal technologies; and establishing best practices.  Of key interest to the audience was a reform era payer solutions platform overview mapping technologies to support the business operations. David Bonham of the Oracle Health Insurance organization moderated the panel and spoke on Oracle’s presence in healthcare and products for payers to help them drive efficiencies and gain a competitive advantage in an ever changing market. Oracle serves healthcare stakeholders with applications such as billing, rating and underwriting, analytics, CRM, enrollment, and products for processing of health insurance claims including pricing and benefits administration, as well as payment of providers through alternative, non-fee for service reimbursement methods. Oracle in Healthcare….Did you know? More than 80 healthcare payers run Oracle applications. More than 300 leading healthcare providers run Oracle applications. 10 out of the top 12 fortune Global 500 healthcare organizations run Oracle applications.

  • Ray Wang: Why engagement matters in an era of customer experience

    - by Michael Snow
    Why engagement matters in an era of customer experience R "Ray" Wang Principal Analyst & CEO, Constellation Research Mobile enterprise, social business, cloud computing, advanced analytics, and unified communications are converging. Armed with the art of the possible, innovators are seeking to apply disruptive consumer technologies to enterprise class uses — call it the consumerization of IT in the enterprise. The likely results include new methods of furthering relationships, crafting longer term engagement, and creating transformational business models. It's part of a shift from transactional systems to engagement systems. These transactional systems have been around since the 1950s. You know them as ERP, finance and accounting systems, or even payroll. These systems are designed for massive computational scale; users find them rigid and techie. Meanwhile, we've moved to new engagement systems such as Facebook and Twitter in the consumer world. The rich usability and intuitive design reflect how users want to work — and now users are coming to expect the same paradigms and designs in their enterprise world. ~~~ Ray is a prolific contributor to his own blog as well as others. For a sneak peak at Ray's thoughts on engagement, take a look at this quick teaser on Avoiding Social Media Fatigue Through Engagement Or perhaps you might agree with Ray on Dealing With The Real Problem In Social Business Adoption – The People! Check out Ray's post on the Harvard Business Review Blog to get his perspective on "How to Engage Your Customers and Employees." For a daily dose of Ray - follow him on Twitter: @rwang0 But MOST IMPORTANTLY....

  • Elastic versus Distributed in caching.

    - by Mike Reys
    Until now, I hadn't heard about Elastic Caching yet. Today I read Mike Gualtieri's Blog entry. I immediately thought about Oracle Coherence and got a little scare throughout the reading. Elastic Caching is the next step after Distributed Caching. As we've always positioned Coherence as a Distributed Cache, I thought for a brief instance that Oracle had missed a new trend/technology. But then I started reading the characteristics of an Elastic Cache. Forrester definition: Software infrastructure that provides application developers with data caching services that are distributed across two or more server nodes that consistently perform as volumes grow can be scaled without downtime provide a range of fault-tolerance levels Hey wait a minute, doesn't Coherence fullfill all these requirements? Oh yes, I think it does! The next defintion in the article is about Elastic Application Platforms. This is mainly more of the same with the addition of code execution. Now there is analytics functionality in Oracle Coherence. The analytics capability provides data-centric functions like distributed aggregation, searching and sorting. Coherence also provides continuous querying and event-handling. I think that when it comes to providing an Elastic Application Platform (as in the Forrester definition), Oracle is close, nearly there. And what's more, as Elastic Platform is the next big thing towards the big C word, Oracle Coherence makes you cloud-ready ;-) There you go! Find more info on Oracle Coherence here.

  • The Earth at Night [Video]

    - by Jason Fitzpatrick
    This fresh video from NASA provides the clearest view of the Earth at night ever seen, thanks to the Suomi National Polar-orbiting Partnership Satellite. Check out the video and accompanying pics to see the stunning views. In daylight our big blue marble is all land, oceans and clouds. But the night – is electric. This view of Earth at night is a cloud-free view from space as acquired by the Suomi National Polar-orbiting Partnership Satellite (Suomi NPP). A joint program by NASA and NOAA, Suomi NPP captured this nighttime image by the satellite’s Visible Infrared Imaging Radiometer Suite (VIIRS). The day-night band on VIIRS detects light in a range of wavelengths from green to near infrared and uses filtering techniques to observe signals such as city lights, gas flares, and wildfires. This new image is a composite of data acquired over nine days in April and thirteen days in October 2012. It took 312 satellite orbits and 2.5 terabytes of data to get a clear shot of every parcel of land surface. This video uses the Earth at night view created by NASA’s Earth Observatory with data processed by NOAA’s National Geophysical Data Center and combined with a version of the Earth Observatory’s Blue Marble: Next Generation. Hit up the link below for the full NASA press release, including more videos and photos.

  • Documentation in Oracle Retail Analytics, Release 13.3

    - by Oracle Retail Documentation Team
    The 13.3 Release of Oracle Retail Analytics is now available on the Oracle Software Delivery Cloud and from My Oracle Support. The Oracle Retail Analytics 13.3 release introduced significant new functionality with its new Customer Analytics module. The Customer Analytics module enables you to perform retail analysis of customers and customer segments. Market basket analysis (part of the Customer Analytics module) provides insight into which products have strong affinity with one another. Customer behavior information is obtained from mining sales transaction history, and it is correlated with customer segment attributes to inform promotion strategies. The ability to understand market basket affinities allows marketers to calculate, monitor, and build promotion strategies based on critical metrics such as customer profitability. Highlighted End User Documentation Updates With the addition of Oracle Retail Customer Analytics, the documentation set addresses both modules under the single umbrella name of Oracle Retail Analytics. Note, however, that the modules, Oracle Retail Merchandising Analytics and Oracle Retail Customer Analytics, are licensed separately. To accommodate new functionality, the Retail Analytics suite of documentation has been updated in the following areas, among others: The User Guide has been updated with an overview of Customer Analytics. It also contains a list of metrics associated with Customer Analytics. The Operations Guide provides details on Market Basket Analysis as well as an updated list of APIs. The program reference list now also details the module (Merchandising Analytics or Customer Analytics) to which each program applies. The Data Model was updated to include new information related to Customer Analytics, and a new section, Market Basket Analysis Module, was added to the document with its own entity relationship diagrams and data definitions. List of Documents The following documents are included in Oracle Retail Analytics 13.3: Oracle Retail Analytics Release Notes Oracle Retail Analytics Installation Guide Oracle Retail Analytics User Guide Oracle Retail Analytics Implementation Guide Oracle Retail Analytics Operations Guide Oracle Retail Analytics Data Model

  • Building vs. Buying a Master Data Management Solution

    - by david.butler(at)oracle.com
    Many organizations prefer to build their own MDM solutions. The argument is that they know their data quality issues and their data better than anyone. Plus a focused solution will cost less in the long run then a vendor supplied general purpose product. This is not unreasonable if you think of MDM as a point solution for a particular data quality problem. But this approach carries significant risk. We now know that organizations achieve significant competitive advantages when they deploy MDM as a strategic enterprise wide solution: with the most common best practice being to deploy a tactical MDM solution and grow it into a full information architecture. A build your own approach most certainly will not scale to a larger architecture unless it is done correctly with the larger solution in mind. It is possible to build a home grown point MDM solution in such a way that it will dovetail into broader MDM architectures. A very good place to start is to use the same basic technologies that Oracle uses to build its own MDM solutions. Start with the Oracle 11g database to create a flexible, extensible and open data model to hold the master data and all needed attributes. The Oracle database is the most flexible, highly available and scalable database system on the market. With its Real Application Clusters (RAC) it can even support the mixed OLTP and BI workloads that represent typical MDM data access profiles. Use Oracle Data Integration (ODI) for batch data movement between applications, MDM data stores, and the BI layer. Use Oracle Golden Gate for more real-time data movement. Use Oracle's SOA Suite for application integration with its: BPEL Process Manager to orchestrate MDM connections to business processes; Identity Management for managing users; WS Manager for managing web services; Business Intelligence Enterprise Edition for analytics; and JDeveloper for creating or extending the MDM management application. Oracle utilizes these technologies to build its MDM Hubs.  Customers who build their own MDM solution using these components will easily migrate to Oracle provided MDM solutions when the home grown solution runs out of gas. But, even with a full stack of open flexible MDM technologies, creating a robust MDM application can be a daunting task. For example, a basic MDM solution will need: a set of data access methods that support master data as a service as well as direct real time access as well as batch loads and extracts; a data migration service for initial loads and periodic updates; a metadata management capability for items such as business entity matrixed relationships and hierarchies; a source system management capability to fully cross-reference business objects and to satisfy seemingly conflicting data ownership requirements; a data quality function that can find and eliminate duplicate data while insuring correct data attribute survivorship; a set of data quality functions that can manage structured and unstructured data; a data quality interface to assist with preventing new errors from entering the system even when data entry is outside the MDM application itself; a continuing data cleansing function to keep the data up to date; an internal triggering mechanism to create and deploy change information to all connected systems; a comprehensive role based data security system to control and monitor data access, update rights, and maintain change history; a flexible business rules engine for managing master data processes such as privacy and data movement; a user interface to support casual users and data stewards; a business intelligence structure to support profiling, compliance, and business performance indicators; and an analytical foundation for directly analyzing master data. Oracle's pre-built MDM Hub solutions are full-featured 3-tier Internet applications designed to participate in the full Oracle technology stack or to run independently in other open IT SOA environments. Building MDM solutions from scratch can take years. Oracle's pre-built MDM solutions can bring quality data to the enterprise in a matter of months. But if you must build, at lease build with the world's best technology stack in a way that simplifies the eventual upgrade to Oracle MDM and to the full enterprise wide information architecture that it enables.

  • Le Logiciel Libre – Omniprésent dans le secteur public

    - by gravax
    NOTE : Cet article a servi de base à du contenu publié en Juin 2011 dans le magazine Acteurs Publics. Créé il y a plusieurs décennies déjà, pour répondre à un besoin de partage de savoir, et de compétences, le Logiciel Libre existe sous plusieurs appellations, à l'origine anglo-saxonnes, dont « Free Software » et « Open Source » sont les plus utilisées. En Anglais, le mot « Free » pouvant signifier à la fois libre et gratuit, cela a créé une certaine confusion qui n'existe pas en Français avec le mot « libre ». Du coup, on voit souvent l’acronyme FOSS ou FLOSS, pour « Free, Libre, Open Source Software » afin d'éliminer l’ambiguïté. De nos jours, dans le secteur public, le logiciel libre est, depuis, devenu omniprésent. Il répond à plusieurs besoins critiques dont le contrôle des coûts, le choix (de partenaire, de logiciel, de fonctionnalités), la liberté de pouvoir modifier les applications pour les adapter à ses propres besoins, la sécurité provenant du fait que de nombreux développeurs et utilisateurs ont pu contrôler la qualité du code. Un autre aspect très présent dans les logiciels libres et l'adhérence quasi-systématique aux standards de l'industrie, qui garantit une intégration simple et facile au système d'information existant. Il y a cependant des éléments à prendre en compte lors des choix de logiciels libres stratégiques. Si l'aspect coûts est clairement un élément de choix qui peut conduire aux logiciels libres, il est principalement dû au fait qu'un logiciel libre existe souvent en version gratuite, librement téléchargeable. Mais ceci n'est que le le sommet de l'iceberg. Lors de la mise en production de logiciels il va falloir s'entourer de services dont l'intégration, où les possibilités de choix d'un partenaire seront d'autant plus grandes que le logiciel choisi est populaire et connu, ce qui conduira à des coups tirés vers le bas grâce à une concurrence saine. Mais il faudra aussi prévoir le support technique. La encore, la popularité du logiciel choisi augmentera la palette de prestataires de support possible. Le choix devra se faire suivant des critères très solides, et en particulier la capacité à s'engager sur des niveaux de service, la disponibilité 24 heures sur 24, 7 jours sur 7 (le pays ne s’arrête pas de fonctionner le week-end ou la nuit), et, éventuellement, la couverture géographique correspondant aux métiers que l'on exerce (un pays comme la France couvrant avec ses DOM et ses TOM une grande partie des fuseaux horaires et zones géographiques de la planète). La plus part des services publics, que ce soit éducation, santé, ou gouvernement, utilisent déjà des logiciels libres. On les retrouve coté infrastructure, avec des produits comme la base de données MySQL, fortement appréciée dans le monde de l'éducation pour construire des plate-formes d'e-éducation en conjonction avec d'autres produits libres tels Moodle, ou GlassFish, le serveur d'applications très prisé des développeurs pour son adhérence au standard Java EE version 6 et sa simplicité de mise-en-œuvre. Linux est extrêmement présent comme système d'exploitation libre dans le datacenter, mais aussi sur le poste de travail. On retrouve des outils de virtualisation tels Oracle VM, issu de Xen, dans le datacenter, et VirtualBox sur le poste du développeur. Avec une telle palette de solutions et d'outils dans le monde du Logiciel libre, Oracle se apporte au secteur public des réponses ciblées, efficaces, aux besoins du marché, y compris en matière de support technique et qualité de service associée.
