Abstract

An Expert System (Es) is a problem-solving computer system that incorporates enough knowledge in somne specialized problem domain to reach a level of performance comparable to that of a human expert. In the heart of an expert system lies the program that "reasons" and makes deductions ("inference engine"). To reason, knowledge both of general rules (e.g. if a person works for a company then he/she gets employee benefits) and of specific declarative facts (e.g. john works for nyu) is needed. With few exceptions, little attention is given in ESs to the handling of very large populations Of specific facts. Since early prototype ESs represented specific facts which were characterized by large variety and a very small population, the inefficiency of data handling was not an issue. As ESs increase in sophistication and ambition, they deal with applications requiring a very large population of facts, often in the form of existing databases manipulated by generalized DBMS. This short paper (see Vassiliou et al 1983 for more details) investigates the technical issues of enhancing expert systems with database management facilities in four stages, leading to the coupling of the ES with a large DBMS. Our vehicles are first-order logic (with Prolog) and relational database management.
