RE: DDM experiences

Classic trade-off between 'fast to deploy', 'easy to use' and 'fast
performance'.  Pick any two and the other one suffers.

'So-so' doesn't really describe the issues you encountered.  Fundamentally,
DDM files are unchanged from S/38 days.  There are a few more objects that
DDM can use, but nothing mind-boggling.

We have a low-volume in-house application that used to run on machine A.
Then we got machine B and some developers sign on to that box exclusively.
DDM files were the simplest answer to this conundrum (database on one box,
programs on two.)  When I say low volume, I mean a few hundred transactions
a day.  Hasn't needed changes since it was implemented 6 years ago.
