public class DBase
extends java.lang.Object

DBase creates databases, tables and interacts with these through JDBC and SQL. Implementation of the databases is with Hypersonic SQL which is written totally in Java. This implementation was created to support the demoonstration security authorisation system. To implement a new (e.g. biometric) auth system then you *WILL* need to change some SQL. It won't hurt.
