fuzzy relational database

First of all, this paper investigates research status of fuzzy relational database and properties of vague set, and then puts forward a generalized fuzzy relational data model on vague set ( VGFRDM) and a fuzzy database structured query language on vague set ( VFSQL).

本文首先探讨了模糊关系数据库的研究现状和Vague集的性质，然后提出了基于Vague集的广义模糊关系数据模型VGFRDM和基于Vague集的模糊数据库查询语言VFSQL。

A fuzzy relational database model with weighted fuzzy attribute values is presented and the concepts of semantic distance and fuzzy users' view are introduced.

本文首先提出了一种属性具有加权模糊值的模糊关系数据库模型，引入了语义距离及模糊视图的概念。
