Abstract
This paper presents an approach for evaluating the Compre hensive Declarative Object Language (CDOL). CDOL is a declarative language that supports the definition, retrieval and manipulation of data over an object-oriented database with support for active rules. We have designed and implemented an intermediate language for the evaluation of CDOL, which is based on the widely used AQUA object algebra. The mapping of a comprehensive application in CDOL to AQUA motivated this AQUA-based intermediate language, known as ABIL. A subset of AQUA operations that were necessary for translating CDOL to AQUA forms the basis of this intermediate language. This paper describes the design of ABIL and illustrates by example the translation of CDOL into ABIL. This paper also includes detailed examples of the evaluation of CDOL’s rule-based query language, which utilizes a binding structure to maintain the bindings for the variables during the evaluation of a CDOL rule.
