HsqlDB

The Hsql Database Engine daemon, wraps HsqlDB 1.8.0. This provides Coadunation with its default sql data source, that can used by other processes such as the timer daemon and message daemons.

The Hsql Database Engine is an in memory database that persists itself to disk on shut down. This means that when the daemon is un-deployed either on shutdown or because it was removed the database information will be stored.
