A rule-based application structure utilizes rules which are stored separately from application programs. The rules are stored in a relational database as objects. A user can modify existing rules and create new rules which are then restored in the database. Because rules are stored as objects in the database, they are easy to locate and retrieve. Because the rules are separate from the application programs, modifications to the rules are easier to accomplish.
