运用XML实现异构数据库的数据转换

Using XML to Achieve Heterogeneous Database Data Conversion

数据源是数据挖掘应用的关键,目前数据库技术的不断发展使得在建立数据源时必须面对异构数据库问题。该文主要对如何在异构数据库中建立数据源进行研究,并利用XML技术在异构数据库中建立数据源模型,且提出了提出了数据转换和预处理技术,利用这两个技术解决在数据库中异构数据如何建立数据源的问题。

The data source is the application of data mining in the key,the development of the database technology makes the da ta source must face the problem of heterogeneous database.This paper focused on the heterogeneous database environment to build data mining data source problem,key research in heterogeneous database based on XML technology in data source model,is proposed by combining the data conversion and data preprocessing technology in heterogeneous database environment to estab lish data source problem.
