In this study, we describe a relatively new approach to address the short-comings of traditional expert-system environments- the infomation-based approach - namely, using a combination of OOP, DBMS, and expert systems. This study illustrates the design of an object-oriented expert system shell (Ellipse) that uses a combination of knowledge bases and databases. Ellipse offers a generalized, flexible system that supports embeddability, rapid prototyping, backward-chaining, explanation facility, linkage to databases, and implementation independence. Further, to illustrate the capability of the shell, we present the design and development of MFA-Mutual Fund Advisor.
