Thank you for response , may be yes , may be no , but i think I have to knew something related DB2 , the story is : we have a Big Project that related re-engineering application , that application was in DB2 .
The project based on Oracle as data base and Unix as operating system.
we want to prevent and observe the vendor and his developer team to make any update or modify in DB2 or Oracle unless we know what they will do.
i hope my question is clear now ?
