| 摘 要： | 本文给出了建立在函数/逻辑型语言LISP-ELP基础上的一个演绎数据库系统模型.该系统比之于建立在PROLOG基础上的演绎数据库系统具有以下优点:有更灵活的控制求解策略、更丰富的查询方式,可与更多的知识表达方式相联系.文中还提出了一种新的知识库管理策略,即多键散列的存取策略,使系统的效率大幅度提高.

| Abstract: | A DDB system, the LEDDB system, based on functional/logic language LISP-ELP is presented.Compared with the PROLOG based DDB system,LED-DBsystem has some desirable features such as flexible control strategy, plentiful ways of query and the capability of associating with various methods of knowledge representation. A new method of knowledge base management, the partitioned Hash function for improving system efficiency, is also incorporated. |
