On the first startup of the Store, it will attempt to automatically create the appropriate tables in the database. The creation will fail if any of the types used is not supported by the user's database, in which case the tables have to be created before starting the store.

This document includes a number of SQL scripts which can be used with various databases to create the tables. Contributions are welcome :)

Note: The JDBC store's goal is to be as compatible as possible. Specific, high performance stores will eventually be developed, based around some vendor XA driver.

This section presents the database schema which is used by the JDBC stores. The types mentioned are the Java types which are expected for each field.

The initialization script for hSQL is the one which is run at the startup of the store.
