SQL server type - You can choose SQL server type: Microsoft SQL, Oracle Database, MySQL server, IBM DB2 Universal Database etc.
Note: when you switched to the "Embedded SQL storage engine", your pldbuser's password will be set to default password. You should change the default password to your own to avoid unauthorized access to your data! Please go to the "Storage Options" tab to do this. The sa's password for the Embedded SQL storage engine remains unchanged.
NOTE: For hard loaded print servers (more then 15...20 printers and with print jobs flow higher then 60 print jobs per second per print queue) we strongly don't recommend you using embedded SQL storage engine (Microsoft SQL Server 2005 Express). Please, use the external SQL server, installed on other computer in your network. As a last resort you can use the Microsoft SQL Server 2005 Express, but is mandatory installed on other computer.
