摘要: 本文首先介绍了演绎数据库DeDB 模型,提出了一种扩充关系模型REDM,并基于REDM 设计并实现了一个演绎数据库系统DFQL/DEDBS,然后讨论了演绎表格查询语言DFQL 的设计与实现。目前,该系统已用于开发了一个实用的决策支持系统。Abstract: In this paper,we present current models for DeDB and propose a new DeDB model,a Relation-Extended Deductive Database Model,based on which a deductive database system（DFQL/ DeDBS）is designed and implemented.A deductive forms query language is discussed in detail.Now the system has been used to develop a practical decision support system.
