Dual License Covers Compact J2ME Database

The new version of McObject's Perst Lite is available under the GNU General Public License (GPL) for open-source projects and as a commercial license for closed-source projects. The tiny database targets Java 2 Platform Micro Edition (J2ME) applications. Perst Lite's object cache does not depend on weak references used by other object-oriented database management systems. Most J2ME implementations don't support weak references because they complicate garbage collection. Perst Lite supports multithreaded access, data encryption, and asynchronous replication along with the B-tree, Patricia Trie, Bit index, T-Tree R-Tree indexes, List, Relation, and Set collections.
