Hi,

about Tools: I made good experiences with Enterprise Architect from Sparx Systems . It is a software modelling tool. http://www.sparxsystems.com.au/

You can import DDL Schemas by using OLEDB and ODBC connections to many database systems. The tool reads the extended Properties from SQL Server Objects and from others (DB2).

You can edit the DDL with a GUI and export DDL scripts.

Best regards,

Stefan
