Separate PK in Jxn Tbl?

It is a good classic screw up, with blame for everyone!

1) ACCESS programmer builds desktop app on his own that looks good for
his immediate needs.
2) Management sees the app and wants to deploy it all over the
company. Hey, why design anything new when we have it already?
3) ACCESS programmer claims it will deploy and and management believes
him.
4) It does not scale, it does not interface with mainframe apps,
external apps, etc. It has no documentation, etc.
5) ACCESS programmer now has a career being the only guy who can keep
the sinking boat up. Never mind how many times a week it has to be re-
booted or how much data is lost.
6) Neither the programmer nor management will scream for help and ask
for a budget. Management would look stupid; programmer would lose his
job and power
