Is it now a real SQL database ?

No. It is still lacking the following important features:

• Stored procedures
• Real transactions
• ACID properties
• Outer joins
• Online backups facility
• Adequate performance
• Support for constraints
• A professional telephone support hotline
• Selecting from DUAL
• ADO connector
• Subqueries
• Support fro GROUP BY
• ...

If you are looking for a commercial grade database, try this one instead!
