databeans is a fully object oriented (not relational) persistence framework for Java, based on the use of the JavaBeans accessor methods to read and write data on disk instead of in the classes' instance fields. It is distributed (through RMI), transactional (with the 4 ANSI isolation levels supported), garbage collected (backed by an on-disk heap called "heapspace"), and has persistent versions of the Collection classes. It aims to provide a full-fledged solution for enterprise application development.
