News: Versant's Eclipse EJB 3 Tooling Proposal Approved

  1. The JSR220-ORM project is providing object relational mapping tooling in Eclipse that supports EJB 3.0 specification runtimes. The goal of the JSR220-ORM Project is to provide visual development tools that facilitate round-trip engineering when using the JSR 220 (EJB 3.0 persistence) and JSR 243 (Java Data Objects) approaches to persistence. The tooling is designed to be extensible allowing alternative input and output artifacts for other runtimes.

    The next Milestone release of the tooling is scheduled for the beginning of August. The Milestone includes support for source synchronized EJB annotations, Live ER diagrams, context sensitive mapping views.

    Scott Ambler, a leading authority on object-relational mapping has joined the project as a developer and architectural advisor. Dirk Le Roux, a committer on this project, was also approved as a committer to the Eclipse Web Tools Platform Project acknowledging this project's code and architectural contributions to the shared frameworks.
  2. JBuilder been doing this for many years already, I don't understand how any of his Eclipse stuff is really new stuff.

    I wonder how long this copycat "invovation" market will continue?

    I guess as long as IBM, Oracle and Microsoft are in business...

    For free ?

    JBuilder is doing what for many years? ... has support for JSR220 :) ? I don't see how this would be a copycat, but anyways would be great if this would include integration with different application servers that would fully implement these specs.
  5. I am looking forward to this. I've viewed the demos in the past (on Versant's site) and if this is anything like what those demos show - it will be VERY good.
  6. Hi all

    I had a few weeks ago a very interesting presentation of Versant and their object database. It seemed very efficient and easy to use, moreover with Java, a full object language.

    I was willing to dig more on the subject but JSF still attracts me more so ... do you have feedback about object databases in general and versant in particular ? Is it really as easy to use and efficient as it seemed to be ?

    Thanks in advance,

    Those presentations were very interesting about five years ago, but the marketplace have since rendered the overwhelming and resounding judgement that these products are not very pragmatic.

    Hence, ObjectStore was acquired by Progress software, which now brands itself as an ESB/SOA vendor.

    Poet Software is now a B2B E-Commerce vendor.

    And Versant is now an EJB 3.0/JDO vendor.

    No doubt some of these vendors may still try to slough off some ODB licenses on you, but be warned that these are most assuredly dead-end product lines.

    I am not sure about that.

    Think about ESB, just-in-time deployments and more than that, enterprise-wide systems. With such constraints, you might want not to deal everywhere with O/R mapping files. OO databases could help there, giving you time to focus on other points.

    Versant was an EJB 3.0/JDO vendor. Not anymore I guess.

    This is far too simple an analysis. Industries don't make 'all or nothing' decisions. There are specialised market segments where OODBs are still widely used, such as some types of financial services, and telecommunications and (very specialised, by an indication of how high-performance ODBs can be - high energy physics!). One of the big advantages of APIs like JDO is that they allow the developer to use relational and object databases interchangeably.
  10. Hi ZedroS,

    I am from Versant, so keep that in mind. However, don't be put-off by some of the narrow minded people who've responded to you.

    Yes, it is very easy to use and very very fast. You can just ask Oracle....who use it in their demand forecast modules ....or Borland ...who use it in their Caliber Requirement Managements modules....or Sabre who use it for airline reservations .... or the American Stock Exchange who use it for trading. The list goes on...

    Not a good solution if you have simple models, small amounts of data, data mining type of query requirements where you want to form projections of data to form input to more queries.

    Otherwise, it rocks! It is the best database on the market. We've plenty of reference customers who will tell you just the same.

    Thanks all of you for your answers. I guess I just have to try it and figure out myself, as usual ;) lol But still I quite believe in the idea. I may be wrong, but what's the fun otherwise ?

    Cheers,
