An Object-Oriented Framework For Role Based Access Control

Access control plays important roles in most application systems. Access control model has been well understood after so many years research and has been widely used in the application systems. Though most application system has access control module, but the special access control requirement still merged within the operations in each application systems. It is still very difficult to make an flexible access control system with traditional software methodology.One way to build a flexible access control system is using Object-Oriented Framework. People has done lots researches in Object-Oriented Framework. Object-Oriented Framework is an software reuse way to solve the problem in special application domain. Using Object-Oriented Framework and Design Patterns can build an reusable access control system.With the exist access control design and our experiences in practice, we build an RBAC Object-Oriented Framework. This Framework implement role management, general access control rules, and take the special access control rule associated with applications as the extension of the framework, so make access control independent of special application domain, when using this framework to implement special access control requirement, we can use subclassing methods to extend the framework.
