Re: Database Re-eng

[Dave Duerr <dduerr@xxxxxxxxxxxxx>]

If you are going to reengineer your database the first thing I would do is
to forget DDS for data files.  DDS is one of the most archaic features left
on the AS/400.  Go with one of the many modern SQL based data modeling
tools such as ERwin(by Logic Works) to design, create, and maintain your
database.  Creating and maintaining a complex database, complete with
referential integrity constraints and triggers, takes days with a modeling
tool, as compared to weeks if not months if using DDS and DB2/400 commands.
 And DDS provides virtually no documentation in regard to relationships,
foreign keys, etc.  The issues you raised are non-issues if using a data
modeling tool.
