摘　　要：Ｅｐｉｃｅｎｔｒｅ中实体间的复杂关系限制了Ｅｐｉｃｅｎｔｒｅ的应用，ＲＤＢＭＳ中广泛采用视图技术可以屏蔽实体间复杂的引用关系及用户不关心的属性，从而改进了Ｅｐｉｃｅｎｔｒｅ的应用。文中从视图应用的角度分析了Ｅｐｉｃｅｎｔｒｅ数据组织的特点，提出了在Ｅｐｉｃｅｎｔｒｅ中建立视图这一思想，并对视图的定义、实现等相应的技术进行了探讨。There are great difficulties in the application of Epicentre because of the complex relationship among the entitis defined in Epicentre. The view widely used in RDBMS may mask the complex relationship and attributes which users are not interested in. In this paper, the view technology is analysed and the feature of the data in Epicentre is given in view point, an idea is presented to build view in Epicentre,and the technology about definition and implemention of view is discussed.
