ADO Database Delphi

Question:
What are the main benefits of the ConstraintBroker?
Answer:
The ConstraintBroker allows you to include check constraints
with the data. That means that when you request the data,
you get the rules. Those rules are automatically and
codelessly enforced. Since they are codelessly enforced,
you don't have to re-write or update your application if
the rule changes. In fact, this is a simple way of
updating the client application without shutting it down.
Every application that uses the ConstraintBroker
automatically has this feature.
