摘要
模糊性是现实世界事物的一个重要属性,不但描述事物的属性特征方面存在着模糊性,而且事物间的相互联系方面也存在着模糊性。本文基于模糊集合理论,实现一个简单模糊关系数据模型,包括模糊关系的定义、模糊关系运算及模糊关系的完整性。并简单介绍了模糊关系数据库技术的应用领域。
Fuzziness is a important attribute of real world object,Not only the attribute characteristic describing object's there is existing fuzziness in aspect,but also mutuality among object contacts aspect existence also is burning fuzziness.The main body of a book based on fuzzy Aggregation theory,Realize a simple blurred relation data model,Include the definition fuzzy relation,Fuzzy relational operators and the integrity of fuzzy relations.And a brief introduction of fuzzy relational database technology applications.
