摘要
企业实现信息化的过程中,在不影响原来应用的情况下,建立有效的信息共享或集中、统一管理的机制成为目前最基本的需求。因此在通过分析目前的数据共享技术的优缺点,提出并实现了一种基于共享数据库的数据共享的模型。重点分析了此系统中的:元数据及其管理;基于ECA规则的增量数据的捕获。最后介绍了此种系统在校园信息化中的应用情况。
During the process of the enterprise information, creation effective system for shared information or data and management of them is the fundamental requirement, without affecting the original system. So a kind of data sharing model based on the shared database is proposed and realized by analyzing the merit and shortcoming of the current data sharing technology. The key technology of this model-meta data and its management, the capture for incremental data-is explained. Finally the situation of the application of this model in the campus information is introduced.
