db4objects Releases 7.0 Version of Leading Open Source Object Database

Native Transparent Activation Further Enhances Ease of Use and Efficiency for Java and .Net Developers

SAN MATEO, Calif., November 13, 2007 – db4objects (, creator of the leading open source object database for Java and .NET, has announced availability of a development (beta) release of version 7.0 of db4o. The new version features Transparent Activation, which makes it even easier than before to retrieve data objects of any complexity in db4o with only one line of code while bolstering db4o's performance lead over incumbents such as Hibernate, relational or non-native object databases. The current release supports native Transparent Activation for Java and db4o collections, a .NET version is planned for December and full support for all collection types in Q1/08.

"This major enhancement of the db4o database makes it easier than ever for developers to work with complex object graphs," said Rodrigo de Olivera, lead at the db4o Project Steering Committee. "Just like people don't like to bother with a manual shift and choose automatic transmission for their cars, Transparent Activation offers a seamless way to work with db4o without having to know what's going on under the hood. You can focus on your application's functionality while db4o makes sure your object model is always ready for action."

In version 7.0, db4o automatically detects the activation depth of object graphs thereby only loading the absolute minimum from disk, which consumes less memory and boosts performance. Unlike implementations with highly abstracted data architectures such as Hibernate, other object-relational solutions or non-native object databases, db4o's embedded Java and .NET engine can leverage Transparent Activation natively to bolster its lead of up to 44x faster performance. Since developers no longer need to manually define the activation depth of the objects they are manipulating, storing or retrieving, they can significantly slash development time.

"Our application makes use of some large and complex object graphs," said Joseph Duda of Nexidia, a leading vendor of speech recognition software based in Atlanta, GA. "For Nexidia, Transparent Activation will reduce the active memory footprint of the application as well as reduce launch times and other graph-loading costs at runtime."

The implementation of Transparent Activation as well as a host of minor enhancements to version 7.0 is driven by db4o's community of nearly 30,000 Java and .NET developers, the world's largest of its kind. Thanks to the collaborative, open source development model, db4objects put object databases back onto the map and makes db4o a mandatory candidate for every innovative Java or .NET system architect, especially when it comes to embedded or mobile software applications.

Registered users of db4o can download the software from the db4o developer site. A beta .NET version of the software is planned for December and a production ready release is expected in the first quarter of 2008 upon approval from the developer community.
