摘要
在现实生活中查询对象既有确定性数据也有大量模糊性数据,现有传统查询技术已无法满足此要求。文章将模糊理论与数据库系统相结合,得到一种数据查询新技术。在介绍了模糊查询和模糊数据的表示之后,提出了建立基于可能性的模糊数据库,并应用于实例中,构筑了在模糊数据库中实现查询的理论和实践框架。
In the realism life, the objects of query involve a great deal of fuzzy data besides accurate data. The traditional query is unable to satisfy the need. In this paper fuzzy theory and database system are combined, and a new data query technique is provided. After introducing the expression of fuzzy query and fuzzy data, the paper offers a fuzzy database based on possibility, and applied it to an instance. A theoretical frame is built for query in the fuzzy database.
