Internals of Derby An Open Source Pure Java Relational Database Engine

Derby is a new incubator project at the Apache Software Foundation, and the future for IBM's Cloudscape technology. This session will start with a short introduction to Derby's functionality and then delve into the depths of Derby's internals. Topics will include the flexible module based architecture, compilation of SQL into Java byte code and exception handling. Lessons learnt from eight years of Java development will be covered, such as performance choices, incorrect decisions and maybe some correct ones!
