Business Rule

A BusinessRule (in a programming context) is knowledge that gets applied to a set of data to create new value. Or it may be a rule about how to create, modify, or remove data. Or perhaps it is a rule that specifies when certain processes occur.

For example, we have a rule about email addresses -- when the Driver Name field on our object identifier changes, we erase the email address. When we receive a new email address, we make sure that it contains an "@" sign and a valid domain not on our blacklist.
