Module - HSQL Datasource (HSQL Datasource)
Implements DB specific bindings to a HSQL database which may be used during unit tests or in environments where no full-blown SQL server is required.
HSQL Tag Query Support
This module implements the tag query handlers using simple, unoptimized LIKE queries. Currently tag queries are very slow with this module, however the interfaces would allow using Hibernate Search to implement very fast tag queries (if needed some day).
HSQL GRIDCoreDB Schema
The schema used inside the HSQL DB is autogenerated by Hibernate uppon start. In contrast to the MSSQL module, the schema is not only validated but also created / updated on demand.
