Db4objects, the open source object database, has tied up with Prosyst, which reportedly owns 50% of the commercial OSGi market, meaning db4objects gets a crack at a swat of automotive, mobile carrier, house alarm and such like implementations. Db4object gives widgets persistence, which means users are less likely to lose data. It's adapted ProSyst's native Java object database to OSGi specifications and released an OSGi-specific distribution. ProSyst, in turn, has adopted db4o as the standard object persistence package in its mBedded Server Professional Edition and as an optional package in its Equinox Edition.
