隐式授权推导模型的设计与实现

Design and Implementation of Deducing Implicit Authorization Model

借助于面向对象的数据模型 (OODM)中的授权概念,提出了在关系型数据库模型下的隐式授权推导模型,并介绍了这种模型的具体实现与应用。应用该模型不仅可以节约存储空间,而且也使授权管理变得容易。

With the help of the authorization concepts of OODM, this paper proposes the deducing implicit authorization model and introduces its implementation in application domain. With this model, not only makes the authorization much easy, but also can reduce the memory resource.
