Hello, I think that database layer is a software interface like any other software interface, if done properly, a dba can convert the stored procedure to any other database without any code change. This way the database specific implementation lives within the database and maintained by the designated dba. Fixups and optimizations can be done in database without touching the code. Backward compatibility layer is much simpler to implement based on stored procedures than complex set of views and tables. Also, accessing the database via different technologies is simpler if there is maintained database interface (stored procedures). I've seen hibernate based java applications that promised to be database independent but at the edges when performance counts, the DAO became HQL, then a special dialect and finally database specific SQLS.
