演绎数据库系统的研究与发展

The Research and Development of Deductive Database Systems

一般认为,演绎数据库(DDB一DeduCtiveDatabase)“诞生”于1978年,至今仅十一年的历史。但是由于其突出的特点,演绎数据库自面世以来就引起了人们的极大重视和广泛兴趣。目前DDB巳构成了数据库学科中的一门独立分支,成为数据库技术中最受重视的前沿研究领域之一。

Deductive database systems are now one of the most important directions in the development of database technologies because of their many attractive properties.They have received widespread intensive interest and very great attention.In this paper We first give a brief overview of the development of deductive database systems.Then We motivate as extensively and thoroughly as possible the directions and significant research topics in this field.The status,importance,trends,research methods of these topics,and the relationship among these topics and other disciplines are also discussed.
