-- 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.

break the code or offering advice on how to improve the code.

-- 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.
