I am wondering if anyone can help me answer this question I have...
At work, we are setup such that our Oracle server runs on a UNIX box and the
client machines are all on NT workstations (not too unusual). We are not
doing any web based programming at all at the moment .. just client/server.
What I want to do, is create some objects that handle the business rules.
For example, if column X is null then column Y and Z can (or must) be empty
... but ... if column X has a value, then columns Y and Z MUST have values
(and only certain values).
