An article at SD Times highlights technology and licensing changes in the latest release of Birdstep's RDM (relational database manager) Embedded 7.0 and its associated software development kit (SDK). A new native Java interface (JNI) speeds performance and obviates the need to rewrite Java programs in C/C++, according to the article, while a freely downloadable SDK enables… developers to begin working immediately without having to wait for purchase requisitions.

A JNI enables Java programmers to write native methods that access OS-specific functions outside the context of the Java virtual machine. Such methods perform better because they do not have to be interpreted. Birdstep's RDM Embedded uses JNI technology to essentially extend the database's C API to Java programmers, enabling higher database performance, the company claims.

The article says Birdstep now believes its RDM Embedded to be smaller yet higher performing than competitor PointBase's embedded database.

The article notes that Birdstep has put up some of its SDKs for free download. Runtime licenses are available for RDM Embedded 7.0 at $10-$100 dollars, and the software runs on a number of platforms including Linux.
