Deen - You are getting some good advice on stored procedures. I haven't had
much luck in that score simply because when programmers get trained in Java,
they (hopefully) get a heavy dose of OOP (Object-Oriented Programming).
Therefore they aren't inclined to consider writing all that in PL/SQL, a
proprietary, non-OOP language.
If you only get one thing to drill in their heads, emphasize
PreparedStatement. This is the Java database call that uses bind variables
on the Oracle side. That applies directly to Java code they write. Sometimes
in J2EE database access is done transparently to the coder.

Subject: Database programming standards
Hi all,
We are in the process of preparation of a RFP for a big project; it is
going to be developed in J2EE, do not know which app server we are going
to use ( probably SUN Iplanet server ), Oracle 9i is the back end.
I am looking for some database programming standards to be written up in
RFP so that we maintenance team can reduce the amount of mess to deal
with after vendor leaves.
So far we do not have any J2EE applications in our shop, so do not know
what kind of a beast it is.
Here is the list of problems I heard from others, do not know how far
they are true:
1) Some Java programs do not close open cursors.
2) On the fly SQLs ( no bind variables ) and each SQL is new for
database causing scalability problems.
3) Applications do not typically make use stored procedures/packages and
all the SQL are dumped into one huge database class file
If anybody already wrote a paper or know some source of these standards,
please forward. Any help in the regard is appreciated.
Thanks for the help
Deen
