> 中文摘要: 查询是一个数据库管理系统的核心功能,一个功能强大而又高效的查询算法的设计是一个成功的数据库系统的关键.文章提出了一个数据库查询优化算法,并实现于联邦数据库系统LNFDBS(Lingnan federal database system).另外,对查询算法在联邦条件下的优化进行了探讨.
Abstract:Query is the core function of a Database Management System. A powerful and effective query algorithm is the key of a successful database system. In the paper, an algorithm of database query optimization is introduced and is implemented on a federal database system——LNFDBS(Lingnan federal database system). The adaptation to the federal database system is also discussed.
