XML技术在基于PowerMart的项目开发中的应用

XML Technology in Project Developing Based on PowerMart

PowerMart是一款性能强大的ETL工具,但在基于PowerMart的项目开发过程中,其界面操作繁琐,开发耗时长。本文通过对powermart.dtd的分析,提出了一种基于XML技术的开发方式,针对具有类似ETL映射或Workflow的作业,设计出统一的XML模版,通过修改XML模版来生成新的Workflow作业。在广东发展银行EDS项目开发过程中证明了这种方法可以显著提高开发效率。

PowerMart is a powerful ETL tool, but during application developing process, it was founded that the interface of PowerMart was somewhat complicated, and the process was time-consuming, with full analysis of powermart, dtd, a new developing technique based on xml was proposed on this article, and for similar to ETL mapping or Workflow design a unified XML templates, by modifying the XML templates to generate a new ETL mapping or Workflow. The development of Guangdong Development Bank project EDS proves that this method can significantly improve develop efficiency.
