Research And Application On Power Integrated Management System Based On XML Data Management

In recent years, XML data management based on relational database has been widely concerned. In the basis of researching on the traditional XML data storage and query technique based on relational database, this paper gives XML relational storage strategy algorithm based on layered model mapping and query processing algorithm in basis of that, finally studies that technology's application in power integrated management system.This paper's researching work mainly includes the followings :( 1) Inductive and summary XML storage ways. In current days, the existing XML storage ways can be roughly classified into four kinds: File system, Native XML database, Object XML database and Relational XML database. In this paper, introducing the four kinds of storage ways, analyzing and comparing their advantages and disadvantages. (2) Researching XML relational storage technology based on layered model mapping. Firstly analyzing several kinds of XML storage ways based on relational database; secondly giving the XML relational storage ways based on layered model mapping. Using this method, we can completely convert the level and structure information in Schema and data information to relational mode. (3) Researching XPath query technology based on relational database after layer mapping. First analyzing the conversion processing method from XPath query language to SQL; secondly designing the conversion processing algorithm. (4) Researching and realizing XML data management technology's application in power integrated management system.Finally in basis of summing the whole paper, putting forward the questions that need be further researched and discussed.
