PDI sources are invaluable when seeking example implementations of databases. Each of the PDI core database support classes is located in the org.pentaho.di.core.database package found in the core/src folder.

Database DatabaseInterface Class
MySQL org.pentaho.di.core.database.MySQLDatabaseMeta
Oracle org.pentaho.di.core.database.OracleDatabaseMeta
PostgreSQL org.pentaho.di.core.database.PostgreSQLDatabaseMeta
