基于XML技术的电力数据库访问程序实现

Implementation for access to power databases based on XML technology

针对电力系统数据平台的异构所造成的信息孤岛问题,提出了一种基于XML语言对电力信息数据库进行查询优化的模型,给出了该模型下的XML编程代码并详述其实现过程。该模型主要使用ASP技术从传统关系型数据库抽取生成XML文档,以该文档为数据查询和操作的桥梁,并利用XSL和JavaScirpt技术对查询结果进行优化显示,使查询结果可以方便地在客户端得到显示。最后通过对远程电网运行参数数据库信息的查询实例研究,实现了相关数据信息查询和发布功能。

In order to resolve problems about information island owing to the heterogeneous platforms of power databases, a new data model by using XML technology to optimize power information database access , as well as the programming code are presented. ASP technology is used to access traditional relational database and generate XML documents in this model, which work as an intermediary of data inquiry and operation. XSL and JavaScirpt technology are also applied to optimize the results of inquiries, which will make data shown in the client terminal easily. Main functions of correlative data query and publication are implemented through an example of remote grid operation database information.
