实现多数据源集成与互操作的扩展视图方法

文中针对多数据源集成与互操作提出了一种扩展视图方法．其基本思想是：以扩展对象模型（ＥＯＭ）为理论基础，通过扩展视图方法实现对多种数据源中的数据（对象）进行多层抽象与封装，以此满足分布环境下不同层次的应用集成需求．文中还讨论了扩展对象模型（ＥＯＭ）、基于扩展视图方法的集成机制，并结合具体的实例给出了扩展视图方法的形式化描述。

An extensible view method for multidatabase integration and interoperation is presented, which supports multi level encapsulation and abstraction of underlying data resource and meets the multi level integration requirements of applications. The extensible object model as the theoretical basis of extensible view method and the integration mechanism based on the extensible view method are discussed, and the formal description of EOM is given.
