The framework library contains utility classes that are generic and useful for building applications that introspect a database via JDBC. These are not intended to be SQuirreLSQL-specific and could be used by other projects JDBC front-end applications. This project is guaranteed to have no code dependencies on other SQuirreLSQL projects and could therefore be used when building a different JDBC front-end application.

There is a newer version: 3.5.0
