摘要
本文将演绎数据库和工程数据库结合起来 ,在分析了它们各自发展现状的基础上 ,给出了一个基于知识的工程数据库模型 ,该模型可以有效地解决上述工程应用问题 .本文着重分析了在实际工程应用环境中知识的新特点 ,给出了演绎工程数据库模型的形式化描述 ,并讨论了在此情况下的推理问题 .最后用知识规则统一表示了数据库完整性约束 .
Deductive database and engineering database are integrated. Their developments are presented and an engineering database model is given based on knowledge which can solve the above problem effectively. The emphasis is given to different properties of the knowledge and the inference problem under the engineering environment. The normal description of the deductive engineering database is also presented. Finally, the expressing of integrity constraints is given via rules.
