Constraints? What's a constraint? ;-)

What's all that fancty talk...this database is over twenty years old, there
was no Oracle, Linux, MySQL etc etc...

Does this database have constraints in any shape or form? If the database is
capable of constraints (most modern databases do, but older ones, I feign
ignorance) and it was implemented properly, it makes life a heck of a lot
easier, since you can a quick overview of the relationships between
different tables - thus making your life easier.
