基于ODS的数据订阅及其更新策略

Data Subscription Based on ODS and Its Refresh Strategy

随着信息技术的不断进步,企业对信息的需求在不断增大,由于职能部门繁多和不同历史条件的限制等原因,各个业务部门会根据各自信息的特点选择不同的数据库系统,如何实现这些业务系统之间数据的共享成了当前研究的课题。针对上述特定的应用,文中介绍了一种基于操作数据存储(ODS)技术的数据订阅,介绍了数据订阅的功能结构和流程。并在此基础上讨论了数据订阅的更新策略。在实际项目实施中,使用数据订阅方案达到了项目预期的目的,很好地满足了实际应用中对数据的一致性、实时性和高效性的需求。

Accompanied by the development of information technology, the requirement of the information for the enterprise is growing vastly. Because of the different functionality of the numerous service department and limits of the history reason ete, every service departments choose most fitful database systems for themselves, How to make those systems shared by others is now a research topic. For this specific application, this issue describes the plan of data subscription based on ODS technique, introduces its functionality and its process. And then discusses the update policy of the data subscription. In the implementation of the project, this data subscription plan achieves the expected goals and well satisfies the requirements for data consistency, real- time and high performance for the special applications.
