Recently, there are several proposals to advance the traditional relational database models. None of them, however, completely manipulates the complex object queries that represent the real-world data model transparently.
In this paper, we not only structure a complex object calculus by means of analyzing several properties in user's complex object queries such as terms in target clause, accessing scopes in range clause, and formulas in qualification clause, but also design translation rules of a complex object query language into a complex object calculus. And, this paper presents correctness of translation rules and completeness of queries through the practical example.
Therefore, this paper contribute to the construction of straight-forward object oriented query processing and the efficient optimization of queries by using the proposed translation rules.
