Abstract :
We develop an efficient algorithm for the query interoperation among existing heterogeneous object-oriented and relational databases. Our algorithm utilizes a canonical deductive database as a uniform representation of object-oriented schema and data. High-order object queries are transformed to the canonical deductive database in which they are partially evaluated and optimized, before being translated to relational queries. Our algorithm can be incorporated into object-oriented interfaces to relational databases or object-oriented federated databases to support object queries to heterogeneous relational databases
