摘要
为按照业务需求整合来自异构数据源的数据,基于OMG的CWM1.1规范和CO-BRA中间件,设计并实现了多数据源协同平台的系统架构。完整介绍了系统的功能模块,着重分析了ETL引擎的核心—数据转换任务执行模块的设计思路及实现过程。从底层实现了对包括中间结果在内的多数据源协同的统一管理,为不同系统之间的元数据交换提供了可能。目前该平台已经在宝钢集团内部进行示范应用,并取得了良好的试验效果。
To integrate data from isomeric data source in term of business requirements, CWM-based multiple-data-source collaborative platform is designed. Modal functions are introduced in detail, and the core of ETL engine, data transformation is analyzed and implemented. Uniform management of multiple-data-source from bottom to intermediate result is roalized. A platform to interchange metadata in dissimilar software systems is provided, which is applied to practice in Bao Group and good ：results are obtained.
