Christian's contribution to ODMBS.ORG

2008/02/24

Christian, co-founder of OOMEGA, has joined ODBMS.ORG's panel of experts.

Recently he has published his thoughts about object-oriented database technology on ODBMS.ORG. The article is called "Lost in translation" and explains the benefits of ODBMS by differentiating the various concepts and discussing them separately.

ODBMS.ORG was created to serve faculty and students at educational and research institutions as well as OO software developers in the open source community or at commercial companies. It is designed to meet the fast-growing need for resources focusing on object database technology and the integration of object-oriented programming and databases.

Christian's short profile and his article can be found here.

Issue tracking with JIRA

2007/08/11

JIRA is a bug tracking and issue tracking application developed to track and manage the issues and bugs that emerge during a project.

OOMEGA is now offering a JIRA instance for its project, so that users as well as developers can submit any issues or bugs regarding OOMEGA. You can access the site at the following URL:

www.oomega.net/jira

Finally we'd like to say thanks to Atlassian. They support our efforts by contributing JIRA to our project.

OOMEGA 2.1 released

2007/07/09

OOMEGA has published its new release: version 2.1. It is available for download here at our homepage.

Now OOMEGA's Java-embedded Query Language does not only support predicates, i.e. the FROM and WHERE clauses, but also handles SELECT, GROUP BY, HAVING and ORDER BY statements.

In contrast to other object-oriented query languages on the market, OOMEGA allows for navigation beyond collection-valued path expressions. Please have a look at the following example query and notice the set comparison:

Query( Person.CID, Select(Select.DISTINCT, Person.F.firstname()), Where( eq( Person.F.children().firstname(), Set("Christian", "Stefano") ) ), null );

The improved query language is well documented in OOMEGA's newly available online documentation: www.oomega.net/wiki.

Please download OOMEGA 2.1 right now. We are looking forward to your feedback, which is highly appreciated, and would willingly discuss with you about our products and features.

Generator publicly available!

2007/04/16

OOMEGA has altered its licensing and pricing model to the benefit of the open source community. Consistent with OOMEGA's intensified open source strategy the registration barrier for downloading the overall software has been eliminated, too.

Now the Generator component is released under the GPL as well, thus you are able to perform model-driven engineering projects or to create database applications without enquiring freebie or purchasing commercial developer licenses. It's free for all of you!

The Incubator is OOMEGA's very last closed-source software module. Thanks to the modelling language SDL - which is part of OOMEGA Core - it is in fact an optional product, so you are not bound to buy developer licenses at all. Moreover, prices have been substantially diminished: now you can purchase OOMEGA Incubator for only 49 € per developer.

According to the new licensing and pricing model, the purchase of OOMEGA Incubator is a pretty good way to support us with a little "donation" which we will give back to you by means of new features.

OOMEGA 2.0 released

2007/02/19

OOMEGA has published its current major release: version 2.0. Today, on February the 19th, the brand-new version has been released and is available for download here at our homepage.

The new release integrates transparent persistency and model-driven software engineering, introduces a Java-embedded query language, extends db4objects, Hibernate and Versant with OOMEGA's data modelling features and many more.

Please download and evaluate OOMEGA 2.0 right now. We are looking forward to your feedback, which is highly appreciated, and would willingly discuss with you about our products and features.
