Abstract

The problems encountered in developing expert database systems (EDSs) are described. It is suggested that what is needed is an EDS shell that is general-purpose and thus alleviates much of the ad hoc tedium associated with constructing present EDSs, and overcomes performance and semantic problems stemming from the present mismatch in the front and back ends of these systems. A language called LDL (logic data language) is described that was developed for this purpose. The discussion is restricted to LDL features with an immediate bearing on the main theme, i.e. tightly coupled systems.
