Graphical representation and storage issues in object-oriented rule modeling
Huy T. Vo, Jeffrey David Peters · 1997
Rules are an important part of any programming language and system. Rules can be employed either to enforce the correctness, integrity or admissibility of databases or database states, or to define requirements specified in the design phase of a software development process. A rule is more than just a simple IF ... THEN construction. Rules can be viewed as objects with distinctive properties and operations, constantly interacting and relating with other objects. Although research has been done on rules, the focus has been mainly on retrieval, activation and firing. Our focus is on the graphical representation and storage of rules and on event modeling in an object-oriented environment.
