 *                                         database.
 * database            server     String   The connect string for the database.
 * internal_logon      n/a        String   A role, such as SYSDBA or SYSOPER,
 *                                         that allows you to log on as SYS.
 * defaultRowPrefetch  prefetch   String   (containing integer value) 
 *                                         The default number of rows to
 *                                         prefetch from the server.

 *                                         getColumns() should report
 *                                         TABLE_REMARKS; equivalent to using
 *                                         setRemarksReporting().
 *                                         (default value is "false") 
 * defaultBatchValue   batchvalue String   (containing integer value) 
 *                                         The default batch value that triggers
