Abstract

“Garbage in, garbage out” is one of the older sayings in the computer industry, and it is absolutely true. If you let garbage data in your system, you have garbage data to work with and no result will be reliable. However, if you don’t allow some flexibility in how the user enters data, users will complain and eventually stop using your system. This chapter shows you how to be both firm and flexible in enforcing data integrity in what users enter in your applications.
