I agree with Brad. The AS400/iSeries/i5 has had a built in FREE
Relational DB since it was announced. Your application my not have
taken advantage of the features but they are there waiting for you.

Subject: Definition of a Relational Data Base
I was recently asked if the iSeries had a data base, or whether our
application used flat files.
I said it had a relational DB, but then I started thinking about the
application's use of the DB.
It's a 25 yo application, and yes it has keyed files (physical as well
as logical of course)and these files are related through foreign keys.
Some logicals of course have select/omit criteria.
But there's no constraints, triggers or procedures being used. There is
no use of DDL. It's all compiled DDS.
That got me wondering if there's a more subtle definition of a
Relational DB.
In other words, would I be correct in repoprting back to this person
(the company architect) that yes we do have a Relational DB but it has
not been implemented in a Relational manner? Or should I just keep my
mouth shut?
