PointBase

PointBase is relational database management system (RDBMS) written in the Java programming language.

In 1998, Bruce Scott, a co-founder of the Oracle Corporation (with Larry Ellison, Bob Miner and Ed Oates), started PointBase Inc. with Jeff Richey (an architect of Sybase) and Daren Race.

It was written in pure Java, supported DCOM and CORBA, and was an object–relational database.

[1] Today (2012) PointBase's SQL Engine is part of Oracle's WebLogic platform.

The evaluation license of PointBase has a database size limit of 30 MB.
