Examples of RDBMSManager

org.jpox.store.rdbms.RDBMSManager
StoreManager for RDBMS datastores. Provided by the "store-manager" extension key "rdbms" and accepts datastore URLs valid for JDBC.
The RDBMS manager's responsibilities extend those for StoreManager to add :
- creates and controls access to the data sources required for this datastore instance
- implements insert(), fetch(), update(), delete() in the interface to the StateManager.
- Providing cached access to JDBC database metadata (in particular column information).
- Resolving SQL identifier macros to actual SQL identifiers.
TODO Change RDBMSManager to share schema information (DatabaseMetaData) with other RDBMSManagers @version $Revision: 1.348 $
