| 摘 要： | 为了将大量的数据以关系数据库的形式存储和保存,将这些关系数据转换成XML文档,给出一个基于查询的关系模式到XML模式转换的有效算法。通过分析数据值基数和用户查询模式,采用列间的相等合并的方式,解决隐式参照完整性问题,最终结果用XML Schema表示。此算法能够避免关系模式转换成错误的XML Schema,并且能够全面有效地表达关系模式中的信息,实现有效信息的充分利用。

| Abstract: | In order to store in the relational database,amount of data was converted into the XML Schema,and an effective algorithm of query from the conversion relation mode to the XML was provided.Through the analysis of the data base and the user mode,using the equal merger between columns,it solved the problem of implicit reference integrity,the results of which adopted the XML Schema.This algorithm could avoid the relation mode converting into a wrong XML Schema,and it could completely and efficiently express the information in the relation mode so as to realize the full utilization. |
