分级的行列级权限系统的设计和实现

为实现权限系统中用户授权的灵活性和数据级的权限控制,在传统权限访问控制模型的基础上,设计了一种基于内存数据库的分级的行列级权限控制模型。通过分级授权实现授权的灵活性和可继承性,通过分级行列级权限实现数据级权限控制,通过内存数据库和预排序遍历树算法实现数据的快速查询。开发了相应的软件系统,与传统权限模型进行了比较,结果表明了该模型的可行性和高效性。

Design and implementation of classable privilege management system on row and tier level

To implement agility of authorization for the users and the data level access control,a privilege management model on the row and tier level,which is based on main memory database,is designed based on the study of traditional access and control model.The agility and inheritance of the authorization is implemented by classable authorization and the data access control is implemented by the classable tow and tier level access control.Besides main memory database and modified preorder tree traversal algorithm ...
