摘要
本文在介绍了遗留系统及相关知识的基础上,阐述了为什么要对地质环境遗留系统进行集成,并比较分析了不同系统集成方法的优缺点,最终选择采用ETL技术进行数据集成的方式。介绍了ETL技术及其应用框架,并用地质环境一张图进行了示例说明。
This paper illustrates why we must integrate geological environment legacy system based on the introduction of the legacy system and related knowledge.In view of the advantages and disadvantages of different system integration methods,this paper chooses ETL technology to integrate data.Then this paper elaborates the ETL technology and its application framework by giving an example of a map of geological environment.
