This is one of the big dangers I see happening around me. Don't fall in this
trap.
You need to understand what is happening behind the scenes. Poor performance
is the result.
A programmer needs to understand how the the code is accessing the database.
That is a different story than understanding the DBMS internals! It is one
of the bad things about CMP EJB's. I do not believe that generated SQL code
can be optimal for all the different relational database backends.
Impossible!
DBA's raise your voice!
