Write a robust rights management system under the code frist of EF: Database model (II)

Start with the database, because it's the EF code frist, so all the design is done in the solution project.

First the data model begins

I've built four models, User,role,action,actiongroup.

The user has actionids in Role,role that stores the ID combination string for the action, Actiongroup as the action group.

So as long as you know the role of user, you can find his corresponding action action, to achieve the function of the rights management.

In conjunction with MVC filtering or inheritance, the need for action to mark the authorization, the function of granulation is achieved.
