一种基于数据隐含涵义的查询方法DCMQ

许多领域的业务中均需要存储用户的数字标识,并在随后的系统业务处理过程中通过这些数字标识对用户信息进行检索。针对这一现状,为了同时满足对用户信息精确和模糊检索的需求,文章以数据挖掘预处理中基于概念树的数据浓缩思想为基础,提出了一种基于数据隐含涵义的有效存储查询方法———DCMQ。解析分析表明该方法不仅可以节省数据库开销,并能有效提高系统的检索速度。

Query Method Based on Data Connotative Meaning

Storing the user's number ID is needed in many fields.In the process of system operation and disposal,the user's information is searched according to the ID.In order to meet the request of exact query and fuzzy enquiry for the user's information,an efficient method based on data connotative meaning is proposed in this paper.This method DCMQ is derived from the idea of the data compression of concept tree in the pretreatment of the data mining.It can not only save database expense but also greatly increase the system efficiency of retrieval.
