Research on role-based access control model of fundamental spatial database system

In this paper, the author use Microsoft.NET as a development platform, taking example for the database system of FSDSJWR. The development and experiment is rose-based, which is superior to traditional frame. The system structure consists four layers such as representation layer, role and privilege administration layer, business logic layer, and data access layer. This model can radically reduce the complexity of system management, meet the need of the multi-user, assign the privilege of the user reasonably, and insure the system run safely on the net.
