摘要

提出一种将OODB查询转换为等价关系查询的形式化方法。转换是通过使用关系谓词图和OODB谓词图来完成的。使用这种基于图的方法的一个优点是，我们可以实现关系查询和OODB查询之间的双向转换。

Translation of object-oriented queries to relational queries

Proposes a formal approach for translating OODB queries to equivalent relational queries. The translation is accomplished through the use of relational predicate graphs and OODB predicate graphs. One advantage of using such a graph-based approach is that we can achieve bidirectional translation between relational queries and OODB queries.<>
