摘要

研究了面向对象数据库中的循环查询处理问题。使用图模型，定义了面向对象数据库系统的数据和循环查询模型。然后讨论了通用的面向对象循环查询的高效处理。为了高效处理，定义了一般循环查询和为给定查询生成的访问计划，并开发了成本模型来确定生成的每个访问工厂的成本。本文还研究了用于实际数据检索的检索算法。

Cyclic query processing in object-oriented databases

Cyclic query processing issues in object-oriented databases are investigated. A data and cyclic query model is defined for an object-oriented database system, using a graph model. Then the efficient processing of a general object-oriented cyclic query is discussed. For efficient processing, a general cyclic query and the access plans generated for a given query are defined and a cost model is developed to determine the cost for each access plant generated. The retrieval algorithms used for actual data retrieval are also investigated.<>
