Vandoni2015-09-292015-09-2919851017-4656https://doi.org/10.2312/eg.19851001This paper describes a design approach that combines knowledge engineering techniques with an interactive graphics program. A prototype for specifying computer systems interactively is used to demonstrate the design approach. The program incorporates a rule-based knowledge engineering module which allows for both data base consistency and the ability to guide the user through an interactive dialogue.10.2312/eg.19851001
