Db4objects began beta-testing Db4O 6.0 four weeks ago. During the beta period, 12,400 copies were downloaded, and many bugs fixed, according to the company.
Db4O 6.0 includes the following new features, according to Db4Objects:
- Lazy queries, a new server-side cursor technology to boost client-server performance
- .NET API changes make db4o as native to .NET as it is to Java
- WIKI-based reference documentation
- Defragmentation is claimed to be up to 14 times faster
Db4o
targets devices running Windows CE and other OSes such as Linux, as well as packaged software products, in markets as diverse as real-time control, office equipment, mobile phones, and web applications. The database stores Java and .NET objects natively, rather than requiring conversion to exotic formats such as SQL. This approach is said to save programmers and processers alike the pain of serializing and unserializing data objects in Java and .Net code.
CEO Christof Whittig said, "One of our bigger design wins is with Ricoh, which will embed Db4O in all of its photocopier and digital office products. We sit on the virtual machine -- in this case, it's Java. We can go wherever Java goes, and of course Java is RTOS-agnostic."
