The Gemini DBAccess project is about providing modularized access to JDBC resources. It exports a DataSourceFactory object so that client applications of the JDBC driver can import and access the features of the driver without having to package the driver as part of the application. The latest release provides support out of the box for the following databases:
HyperSQL (HSQLDB) v.2.x
The databases and drivers must be downloaded separately and installed.
