• We're Subversion Geeks and we want to know the benefits of Mercurial

  - by Matt

  Having read I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS. I have a related follow up question. I read that question and read the recommended links and videos and I see the benefits but I don't see the overall mindshift people are talking about. Our team is of 8-10 developers that work on one large code base consisting of 60 projects. We use Subversion and have a main trunk. When a developer starts a new Fogbugz case they create a svn branch, do the work on the branch and when they're done they merge back to the trunk. Occasionally they may stay on the branch for an extended time and merge the trunk to the branch to pick up the changes. When I watched Linus talk about people creating a branch and never doing it again, that's not us at all. We create probably 50-100 branches a week without issue. The biggest challenge is the merging but we've gotten pretty good at that as well. I tend to merge by fogbugz case & checkin rather than the entire root of the branch. We never work remotely and we never make branches off of branches. If you're the only one working in that section of the code base then the merge to the trunk goes smoothly. If someone else had modified the same section of code then the merge can get messy and you might need to do some surgery. Conflicts are conflicts, I don't see how any system could get it right most of the time unless if was smart enough to understand the code. After creating a branch the following checkout of 60k+ files takes some time but that would be an issue with any source control system we'd use. Is there some benefit of any DVCS that we're not seeing that would be of great help to us?

• Compiling C++ code with mingw under 12.04

  - by golemit

  I tried to setting up compiling of the C++ projects under my Ubuntu 12.04 by mingw with QT libraries. The idea was to get executable independent from variations of target Windows versions and development environments of my colleagues. It was successfully implemented under OpenSuse 12.2 with mingw32 and some additional libraries including mingw32-libqt4 and some others. Fine. However when trying to do the same under Ubuntu 12.04 with mingw-w64 including latest libraries QT-4.8.3 copied from Windows there were always errors. No luck. The typical errors in these attempts can be seen in attachments. The commands used: qmake -spec /path_to_my_conf/win32-x-g++ my_project.pro make Can someone give a hint of the problem source? I would appreciate a good advice.

• Technology focussed solutions for Financial Services

  - by ambreesh

  Just finished a short trip to London, where I presented our 3 new technology solutions for Financial Services to the Oracle Client Advisors for the top accounts in EMEA. The solutions were well received by all, with opportunities for all 3 in all the top accounts. The solutions that we are focused on this FY are - Large Scale Data Management platform - Extreme Java platform - Banking Modernization platform, which includes Payments Consolidation (Wholesale and Retail), Core Banking Modernization and Mainframe Offload. My team's responsibility is to build the resilient platform that our financial customers can run their applications on. If they chose Oracle's applications such as Flexcube or Reveleus, we have done the hard work to tightly integrate these applications with our LSDM and BM platforms. If however a customer decides to run a competitive application, they should rest assured that we have done the best possible integration work with those applications too. And in the case of Capital Markets where Oracle does not have trading or risk assets, our LSDM and EJP solutions work with our partner applications such as GoldenSource, PolarLake, Calypso to name a few.  I will detail these solutions in subsequent posts.

• Making a perfect map (not tile-based)

  - by Sri Harsha Chilakapati

  I would like to make a map system as in the GameMaker and the latest code is here. I've searched a lot in google and all of them resulted in tutorials about tile-maps. As tile maps do not fit for every type of game and GameMaker uses tiles for a different purpose, I want to make a "Sprite Based" map. The major problem I had experienced was collision detection being slow for large maps. So I wrote a QuadTree class here and the collision detection is fine upto 50000 objects in the map without PixelPerfect collision detection and 30000 objects with PixelPerferct collisions enabled. Now I need to implement the method "isObjectCollisionFree(float x, float y, boolean solid, GObject obj)". The existing implementation is becoming slow in Platformer games and I need suggestions on improvement. The current Implementation: /** * Checks if a specific position is collision free in the map. * * @param x The x-position of the object * @param y The y-position of the object * @param solid Whether to check only for solid object * @param object The object ( used for width and height ) * @return True if no-collision and false if it collides. */ public static boolean isObjectCollisionFree(float x, float y, boolean solid, GObject object){ boolean bool = true; Rectangle bounds = new Rectangle(Math.round(x), Math.round(y), object.getWidth(), object.getHeight()); ArrayList<GObject> collidables = quad.retrieve(bounds); for (int i=0; i<collidables.size(); i++){ GObject obj = collidables.get(i); if (obj.isSolid()==solid && obj != object){ if (obj.isAlive()){ if (bounds.intersects(obj.getBounds())){ bool = false; if (Global.USE_PIXELPERFECT_COLLISION){ bool = !GUtil.isPixelPerfectCollision(x, y, object.getAnimation().getBufferedImage(), obj.getX(), obj.getY(), obj.getAnimation().getBufferedImage()); } break; } } } } return bool; } Thanks.

• Who should write the test plan?

  - by Cheng Kiang

  Hi, I am in the in-house development team of my company, and we develop our company's web sites according to the requirements of the marketing team. Before releasing the site to them for acceptance testing, we were requested to give them a test plan to follow. However, the development team feels that since the requirements came from the requestors, they would have the best knowledge of what to test, what to lookout for, how things should behave etc and a test plan is thus not required. We are always in an argument over this, and developers find it a waste of time to write down things like:- Click on button A. Key in XYZ in the form field and click button B. You should see behaviour C. which we have to repeat for each requirement/feature requested. This is basically rephrasing what's already in the requirements document. We are moving towards using an Agile approach for managing our projects and this is also requested at the end of each iteration. Unit and integration testing aside, who should be the one to come up with the end user acceptance test plan? Should it be the reqestors or the developers? Many thanks in advance. Regards CK

• Which Open Source Licenses can address concerns for an Open Source Game Engine?

  - by Chris

  I am on a team that is looking to open source an engine we are building. It's intended as an engine for Online RPG style games. We're writing it to work on both desktops and android platforms. I've been over to the OSI http://opensource.org/licenses/category to check out the most common licenses. However, this will be my first time going into an open source project and I wanted to know if the community had some insight into which licenses might be best suited. Key licensing concerns: Removing or limiting our liability (most already seem to cover this, but stating for completeness). We want other developers to be able to take part or all of our project and use it in their own projects with proper accreditation to our project. Licensing should not hinder someone's ability to quickly use the engine. They should be able to download a release and start using it without needing to wait on licensing issues. Game content (gfx, sound, etc.) that is not part of the engine should be allowed to be licensed separately. If someone is using our engine, they can retain full copy right of their content, including engine generated data. Our primary goal is exposure, which is why we're going open source to start with. Both for the project and for the individuals developing it. Are there any licenses that can require accreditation visible to players? While I'd put our primary goal as exposure, for licensing the accreditation is less of a concern. From what I've read through (and have been able to understand) it doesn't seem like any of the licenses cover anything that is produced by the licensed software. Are there any that state this specifically, or does simply not mentioning it leave it open for other licensing? Are there any other concerns that we should consider? Has anyone had any issues using any of these licenses?

• Introducing a (new) test method to a team

  - by Jon List

  A couple of months ago i was hired in a new job. (I'm fresh out of my Masters in software engineering) The company mainly consists of ERP consultants, but I was hired in their fairly small web department (6 developers), our main task is ERP/ecom integration (ERP-integrated web shops). The department is growing, and recently my manager asked me to start thinking about introducing tests to the team, i love a challenge, but frankly I'm a bit scared (I'm the least experience member of the team). Currently the method of testing is clicking around in the web shop and asking the customer if the products are there, if they look okay, and if orders are posted correctly to the ERP. We are getting a lot of support cases on previous projects, where a customer or a customer's customer have run into errors, which - i suppose - is why my manager wants more structured testing. Off the top of my head, I though of some (obvious?) improvements, like looking at the requirement specification, having an issue tracker, enabling team members to register their time on a "tests"-line on the budget, and to circulate tasks amongst members of the team. But as i see it we have three main challenges: general website testing. (javascript, C#, ASP.NET and CMS integration tests) (live) ERP integration testing (customers rarely want to pay for test environments). adopting a method in the team I like the responsibility, but I am afraid that I'm in a little bit over my head. I expect that my manager expects me to set up some kind of workshop for the team where I present some techniques and ideas and where we(the team) can find some solutions together. What I learned in school was mostly unit testing and program verification, not so much testing across multiple systems and applications. What I'm looking for here, is references/advice/pointers/anecdotes; anything that might help me to get smarter and to improve the current method of my team. Thanks!! (TL;DR: read the bold parts)

• What is a good way to share internal helpers?

  - by toplel32

  All my projects share the same base library that I have build up over quite some time. It contains utilities and static helper classes to assist them where .NET doesn't exactly offer what I want. Originally all the helpers were written mainly to serve an internal purpose and it has to stay that way, but sometimes they prove very useful to other assemblies. Now making them public in a reliable way is more complicated than most would think, for example all methods that assume nullable types must now contain argument checking while not charging internal utilities with the price of doing so. The price might be negligible, but it is far from right. While refactoring, I have revised this case multiple times and I've come up with the following solutions so far: Have an internal and public class for each helper The internal class contains the actual code while the public class serves as an access point which does argument checking. Cons: The internal class requires a prefix to avoid ambiguity (the best presentation should be reserved for public types) It isn't possible to discriminate methods that don't need argument checking   Have one class that contains both internal and public members (as conventionally implemented in .NET framework). At first, this might sound like the best possible solution, but it has the same first unpleasant con as solution 1. Cons: Internal methods require a prefix to avoid ambiguity   Have an internal class which is implemented by the public class that overrides any members that require argument checking. Cons: Is non-static, atleast one instantiation is required. This doesn't really fit into the helper class idea, since it generally consists of independent fragments of code, it should not require instantiation. Non-static methods are also slower by a negligible degree, which doesn't really justify this option either. There is one general and unavoidable consequence, alot of maintenance is necessary because every internal member will require a public counterpart. A note on solution 1: The first consequence can be avoided by putting both classes in different namespaces, for example you can have the real helper in the root namespace and the public helper in a namespace called "Helpers".

• Generic Repositories with DI & Data Intensive Controllers

  - by James

  Usually, I consider a large number of parameters as an alarm bell that there may be a design problem somewhere. I am using a Generic Repository for an ASP.NET application and have a Controller with a growing number of parameters. public class GenericRepository<T> : IRepository<T> where T : class { protected DbContext Context { get; set; } protected DbSet<T> DbSet { get; set; } public GenericRepository(DbContext context) { Context = context; DbSet = context.Set<T>(); } ...//methods excluded to keep the question readable } I am using a DI container to pass in the DbContext to the generic repository. So far, this has met my needs and there are no other concrete implmentations of IRepository<T>. However, I had to create a dashboard which uses data from many Entities. There was also a form containing a couple of dropdown lists. Now using the generic repository this makes the parameter requirments grow quickly. The Controller will end up being something like public HomeController(IRepository<EntityOne> entityOneRepository, IRepository<EntityTwo> entityTwoRepository, IRepository<EntityThree> entityThreeRepository, IRepository<EntityFour> entityFourRepository, ILogError logError, ICurrentUser currentUser) { } It has about 6 IRepositories plus a few others to include the required data and the dropdown list options. In my mind this is too many parameters. From a performance point of view, there is only 1 DBContext per request and the DI container will serve the same DbContext to all of the Repositories. From a code standards/readability point of view it's ugly. Is there a better way to handle this situation? Its a real world project with real world time constraints so I will not dwell on it too long, but from a learning perspective it would be good to see how such situations are handled by others.

• What's the best project management software for internal dev. 5 man shop

  - by P.Brian.Mackey

  I work for a large corporation, but we do small intranet web application development. Our project management tracking sucks. Its custom software built by a jr. intern. For what its worth, our development style is akin to agile, but there's nothing set in stone...very customer oriented approach. I need project tracking that meets the criteria: Intranet, internal products. Mostly maintenance, some new development. 5 developers 12 products 1 hands-off manager. He really just wants to know estimated man hours, due date for dev, QA and release. Along with a short description of the project. Free or super cheap. Bonus Simple pretty UI. Think pretty charts. Hope I covered everything. Please ask for any clarification. If you read dreaming in code, the company uses some project tracking software that sounds pretty sweet. Note, we do have Team Foundation Server. I already tried pushing its use as PM tracking, but its too complicated. I can't get people to sit and train. So this software has to be easy.

• Sharing business logic between server-side and client-side of web application?

  - by thoughtpunch

  Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

• How to create an Orthographic display in OpenGL (ES) that handles different screen sizes and orientations?

  - by Piku

  I'm trying to create an iPad/iPhone game using GLES2.0 that contains a 3D scene with a heads-up-display/GUI overlaid on the top. However, this problem would also apply if I were to port my game to a computer and run the game in a resizable window, or allow the user to change screen resolutions... When trying to make the 2D GUI/HUD work I've made the assumption that all I'm really doing is drawing a load of 2D textured 'quads' on the screen and am trying to treat the orthographic projection as an old-style 2D display with 0,0 in the upper left and screenWidth,ScreenHeight in the lower right. This causes me all sorts of confusion when I rotate my ipad into Landscape mode since I can't work out what to put into my projection and modelview matrices to turn everything around the right way. It also gets messy if I want to support the iPad's large screen, an iPhone or a Retina display since I have to then draw three sets of textures for everything and work out which ones to use. Should I be trying to map the 2D OpenGL co-ords 1:1 with the screen? While typing out this question it occurs to me that I could keep my origin in the centre, still running -1/+1 along the axes. This would let me scale my 2D content appropriately on the different screen sizes, but wouldn't I end up with the textures being scaled and possibly losing quality? I'm using OpenGLES 2.0 and have a matrix library that has equivalents to the GLES1.1 glOrthof() and glFrustrum() calls.

• Pattern for a class that does only one thing

  - by Heinzi

  Let's say I have a procedure that does stuff: void doStuff(initalParams) { ... } Now I discover that "doing stuff" is quite a compex operation. The procedure becomes large, I split it up into multiple smaller procedures and soon I realize that having some kind of state would be useful while doing stuff, so that I need to pass less parameters between the small procedures. So, I factor it out into its own class: class StuffDoer { private someInternalState; public Start(initalParams) { ... } // some private helper procedures here ... } And then I call it like this: new StuffDoer().Start(initialParams); or like this: new StuffDoer(initialParams).Start(); And this is what feels wrong. When using the .NET or Java API, I always never call new SomeApiClass().Start(...);, which makes me suspect that I'm doing it wrong. Sure, I could make StuffDoer's constructor private and add a static helper method: public static DoStuff(initalParams) { new StuffDoer().Start(initialParams); } But then I'd have a class whose external interface consists of only one static method, which also feels weird. Hence my question: Is there a well-established pattern for this type of classes that have only one entry point and have no "externally recognizable" state, i.e., instance state is only required during execution of that one entry point?

• Should a stack trace be in the error message presented to the user?

  - by Vilx-

  I've got a bit of an argument at my workplace and I'm trying to figure out who is right, and what is the right thing to do. Context: an intranet web application that our customers use for accounting and other ERP stuff. I'm of the opinion that an error message presented to the user (when things crash) should include as much information as possible, including the stack trace. Of course, it has to start with a nice "An Error has occurred, please submit the below information to the developers" in large, friendly letters. My reasoning is that a screenshot of the crashed application will often be the only easily available source of information. Sure, you can try to get a hold of the client's systems administrator(s), attempt to explain where your log files are, etc, but that will probably be slow and painful (talking to the client representatives mostly is). Also, having an immediate and full information is extremely useful in development, where you don't have to go hunting through the log files to find what you need on every exception. (But that could be solved with a configuration switch.) Unfortunately there has been some kind of "Security audit" (no idea how they did that without the sources... but whatever), and they complained about the full exception messages citing them as a security threat. Naturally, the clients (at least one that I know of) has taken this at face value and now demands that the messages be cleaned. I fail to see how a potential attacker could use a stack trace to figure anything out he couldn't have figured out before. Are there any examples, any documented proof of anyone ever doing that? I think that we should fight this foolish idea, but perhaps I'm the fool here, so... Who's right?

• Profit : August, 2012

  - by user462779

  August 2012 issue of Profit is now available online. Way back in 2003, I wrote my first feature for Profit. It was titled “Everything You Always Wanted to Know About Application Servers (But Were Afraid To Ask),” and it discussed “cutting-edge” technologies like portals and XML and the brand-new Java Platform, Enterprise Edition (Java EE; we’re now on Java EE 7). But despite the dated terms I used in my Profit debut, I noticed something in rereading that old story that has stayed constant: mid-tier technology is where innovative enterprise IT projects happen. It may have been XML in 2003, but it’s SOA in 2012. While preparing the August issue of Profit was more than just a stroll down memory lane for me, it has provided a nice bit of perspective about what changes and what doesn’t in this dynamic IT industry. Technologies continuously evolve—some become standard practice, some are revived or reinvented, and some are left by the wayside. But the drive to innovate and the desire to succeed are business principles that never go out of fashion. Also, be sure to check out the Profit JD Edwards Special Issue 2012 (PDF), featuring partner profiles, customer successes, and Oracle executive interviews.

  Understanding Oracle BI 11g Security vs Legacy Oracle BI 10g | Christian Screen "After conducting a large amount of Oracle BI 10g to Oracle BI 11g upgrades and after writing the Oracle BI 11g book," says Oracle ACE Christian Screen, "I still continually get asked one of the most basic questions regarding security in Oracle BI 11g; How does it compare to Oracle BI 10g? The trail of questions typically goes on to what are the differences? And, how do we leverage our current Oracle BI 10g security table schema in Oracle BI 11g?" Process Oracle OER Events using a simple Web Service | Bob Webster Bob Webster's post "provides an example of a simple web service that processes Oracle Enterprise Repository (OER) Events. The service receives events from OER and utilizes the OER REX API to implement simple OER automations for selected event types." Oracle Fusion Middleware Security: Attaching OWSM policies to JRF-based web services clients | Andre Correa "OWSM (Oracle Web Services Manager) is Oracle's recommended method for securing SOAP web services," says Oracle Fusion Middleware A-Team member Andre Correa. "It provides agents that encapsulate the necessary logic to interact with the underlying software stack on both service and client sides. Such agents have their behavior driven by policies. OWSM ships with a bunch of policies that are adequate to most common real world scenarios." His detailed post shows how to make it happen.

• What did programmers do before variable scope, where everything is global?

  - by hydroparadise

  So, I am having to deal with seemingly archiac language (called PowerOn) where I have a main method, a few datatypes to define variables with, and has the ability to have sub-procedures (essentially void methods) that does not return a type nor accepts any arguements. The problem here is that EVERYTHING is global. I've read of these type of languages, but most books take the aproach "Ok, we use to use a horse and cariage, but now, here's a car so let's learn how to work on THAT!" We will NEVER relive those days". I have to admit, the mind is struggling to think outside of scope and extent. Well here I am. I am trying to figure out how to best manage nothing but global variables across several open methods. Yep, even iterators for for loops have to be defined globaly, which I find myself recycling in different parts of my code. My Question: for those that have this type experience, how did programmers deal with a large amount of variables in a global playing field? I have feeling it just became a mental juggling trick, but I would be interested to know if there were any known aproaches.

• Metaphor for task synchronization [closed]

  - by nkint

  I'm looking for a metaphor. A friend of mine taught me to use metaphors from nature, everyday life, math, and use them to design my projects. They can help in creating a better design or better understanding or the problem, and they are cool. Now I'm working on a project with hardware and micro-controllers in C. For convenience, I have decided to use multiple micro-controllers as co-processor units for real-time (the slaves) and a master. This has saved me a lot of headache: I can code the main logic in the master without paying too much attention to super optimizing everything; I don't care if I need some blocking-call; I don't worry about serial communication with the computer. I just send messages to the slaves and they are super fast super in real time. I like my design and it seems to work well. So here are the important concepts that I'm trying capture in the metaphor: hierarchy of processing Not using one big brain but rather several small, distributed brain units using distributed power or resources I'm looking for a good metaphor for this concept of having one unit synchronize the work of all the others. Preferably, the metaphor would come from nature, biology, or zoology.

• Evolution of mainstream programming languages: simplicity versus complexity.

  - by Giorgio

  I had posted this question on http://stackoverflow.com but I was suggested that it may be more appropriate to post it on this forum. I did a quick search on this site and it seems to me that this question has not been asked yet. Please give me a hint if the topic has been raised already by someone else. Update I have rephrased this question, removed personal opinions and made it shorter. I hope in this way it is better suited for this forum. By looking at the recent development of Java (Java 7) and C++ (C++0x) I see that new features are added to these languages. For sure this makes it easier to use certain programming idioms, adding to the productivity of developers. On the other hand, there might be the following risks A language becomes too big, complex, and difficult to understand. It lacks coherence in the design, e.g. if it mixes different paradigms like object-orientation and functional programming, which might not fit well together. Questions: what is more important to you as a developer: to have a rich language that captures a large collection of programming idioms or to have a small language that aims at coherence and simplicity (of course, with a good deal of libraries and tools accompanying it)? Or is it possible to have both? With respect to these issues: How do you judge the current evolutions of main-stream programming languages like Java or C++? Are they becoming too complex, less intuitive? Do they have enough features? Do they need more? Are they still easy enough to understand and use?

• Hosting several HTTP servers on single domain name

  - by Nakilon

  Several people have got a single domain name server.company.com server, where they are now supposed to host their infrastructure or temporal projects, written in different ways even in different programming languages. How do they divide the domain? Split into subdomains: john.server.company.com, kate.server.company.com, etc. This would need a lot of admins' assistance, time, etc. -- there would be no way for John and Kate to do it themselves. Split into url namespaces: server.company.com/john/, server.company.com/kate/, etc. Pro: They now can make a single welcome page at root with any additional info (if they need?) Con: Each server would need to know their namespace string constant, and hrefs like / whould need patching. Split into ports: server.company.com:8080, server.company.com:8081, etc. and make a single :80 welcome page. Pro: They still can make a single welcome page at :80 Con: ??? I would like to know more pros and cons for 2 and 3 solution.

• How do I pick which agency to go through?

  - by RoboShop

  I work in a town where the majority of work comes from the government. As a contractor, I generally have to apply for work through agencies which are on the government's preferred vendor's list. Most jobs are publicly listed and to apply for them, you generally need an agency to represent you by submitting your application with a rate which is usually your rate plus their commission. I've been trying to figure out what the agencies do, and it seems a large part of what they do is 1) get on that preferred vendor's list and 2) forward resumes. So right now, my policy is that since their commission affects how expensive I am, one - I don't work with companies that do not disclose their margin. And two, I go for the agency that takes the least amount of commission for the job I want to apply for. IS that the best approach? I would think applying for a job with the most competitive rate is the best approach but I also wonder whether which agency you're applying through actually matter? I know some agencies actually build personal relationships with senior managers but how do I know which one? How do I know that actually affect my job prospects? What criteria should I use to decide which agent I go through for the job?

• Oracle Financials In the News

  - by Di Seghposs

  Coming off of OpenWorld and all the excitement around Oracle’s “Cloud” strategy, we thought we’d share what others had to say recently about Oracle’s financial solutions in and out of the cloud: Information Management, the educated reader’s choice for the latest news, commentary and feature content serving the information technology and business community, had an interesting blog post from Bill McNee of Saugatuck Technology, entitled, “A Bull Market for Finance Cloud Apps”. In the post, he highlights Oracle as one of the ‘significant players’ in the space… Oracle: As recently announced, Oracle is now aggressively marketing its Oracle Fusion Financials Cloud Service to midsize and large enterprise customers. While we anticipate that this solution set will primarily appeal to a portion of the existing Oracle customer footprint, rather than taking share from competitors, it is embedding some strong mobile and social capabilities that should help it gain traction. Read the full article - “A Bull Market for Finance Cloud Apps” Ventana Research, a leading benchmark research and advisory services firm, made mention to Oracle Fusion Financials in a recent blog post. While we all know ‘boring is cool’, it was cool to see Robert Kugel, SVP Research, discussing Oracle’s Fusion Financials strategy. Here’s some excerpts: “For at least the next five years I believe Oracle has a good strategy, because the transition from the existing Oracle ERP offerings to Fusion Financials can be less painful than similar migrations…” “Deploying Fusion GL can facilitate a more consistent and faster way to execute finance department functions.” “Fusion Financials is the go-forward accounting and financial applications suite that will coexist…” “Whether or not it’s time to migrate, I think all users of Oracle’s E-Business Suite, Oracle Applications, PeopleSoft and JD Edwards software should consider Fusion GL as part of an ongoing program to extract more value from their core financial systems.” Read the full article - “Oracle Fusion Financials: Boring is Cool”
