The authors describe the architectural over-view of a research project called ILEX. The discussion focuses on a unified approach for all relational query languages. A universal interface supporting three typical query languages: ML based on ISBL, EL based on SOL, and PL based on QBE, has been implemented entirely in prolog. The translation of queries from a variety of query languages into a canonical logic form is illustrated. A simple but effective dynamic optimisation strategy is described. By means of knowledge information processing many different query languages can be implemented using the same database management software. Each query language supported in a cleanly-supported component and can be modified independently from the rest of the system, and the underlying software can be changed without requiring any change at the user interface. This approach should yield great benefits in reduced cost and increased flexibility of implementation and application. 12 references.
