-- db4o 7.0 RELEASED WITH TRANSPARENT ACTIVATION --

db4objects has announced availability of a development (beta) release of version 7.0 of db4o for Java for immediate download from the db4o Download Center.

db4o 7.0 features Transparent Activation (TA), 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.

Find the complete release notes in New in Version 7.0 (PDF).

More information in Carl's blog posts The 7th Dimension and detailled item by item release notes.


-- XtremeConnect VIRTUAL PAIRING SERVICE LAUNCHED --

db4objects has launched its new premium service offering dDN Enterprise which includes the unique new support service XtremeConnect.

XtremeConnect allows developers to directly connect with a db4o specialist for a remote pairing session that enables joint design reviews, problem solving or debugging with unprecedented efficiency.

This service evolved from db4objects' engineering processes that are are based on Extreme and Agile practices and, by necessity, include some ingenuity to bridge the geographic gaps between remote engineers. With the help of Skype and VNC engineers always develop in pairs, one writing the code, the other writing tests trying to break the code or offering advice on how to improve the code.

As a dDN Enterprise subscriber you can click on the XtremeConnect button located in the new ObjectManager Enterprise productivity tool or the db4objects Customer Portal to schedule a one-on-one session with a db4o specialist.

For more information and instructions on how to obtain this product, please visit the XtremeConnect Product Information page.


-- db4o 6.4 READY FOR PRODUCTION --

db4o 6.4 has now been moved to PRODUCTION status, the equivalent of a candidate for stable, which means it is recommended for evaluation and product development. In this phase the feature set stays consistent and only bug fixes are be applied to the code. In Q1/2008 db4o 6.4 will move to STABLE, the version recommended for product shipment. Starting with release 7.0, STABLE releases are only available to commercial customers.

Get version 6.4 Production from the db4o Download Center.


-- NEW ObjectManager Enterprise LAUNCHED --

ObjectManager Enterprise is a completely new design of the ObjectManager productivity tool. It provides great database browsing and maintenance features and adds the ability to access services such as case management and XtremeConnect, our new virtual pairing service.

This first release of OM-Enterprise is implemented as Visual Studio 2005 plug-in with an Eclipse version to follow towards the end of the year. By leveraging the plug-in framework users never have to leave their favorite development environment to test their db4o database.

ObjectManager Enterprise is exclusively available to all customers subscribing to the new dDN Enterprise offering. You can download a trial version of ObjectManager Enterprise here.

The previous ObjectManager 6 is still available under GPL here and is maintained by the db4o community, together with a host of IDE plug-in projects.

-- db4o - THE DATABASE FOR GOOGLE'S ANDROID --

Google has created a stir with the release of the Android SDK, a comprehensive software platform for mobile phones that was recently announced at the Open Handset Alliance. The Java programming API and the fact that it is free makes it an ideal platform for millions of application developers -- and immediately compatible to db4o.

Only hours after the Android release the db4objects team had some quick evaluations of the SDK running with db4o. The result: db4o runs without a snag on Android and is, out of the box and without optimization, already 20% faster than SQLite.

Read more on Christof's blog here and Carl's blog here. You will definitely see more news around db4o and Android. Stay tuned!
