The Design And Implementation Of Competence Model Based On The Data Source

As the development of information technology and computer technology, database system has been extensively applied. Therefore, the database security protection is becoming increasingly important. Access control system is essential for all modules. This paper focus on the access control technology, role-based access control policy model, a new model of competence is applied in the form of components.The main research work of thesis are as follows:1> Analyze the common access control mechanism.2> Propose a role-based database access control scheme, and implementdatabase resources granular access control.3> the design of data rights management take components technology, and analysis the demand of the data management competence, and design management of the component which is flexibility. The management of the component achieve that Implementing the cross-platform components, and increasing the reusability and maintainability of components.4> The realization of the Data rights management components based on the MVC and a role-based database access control programme. Secondary Packaging Hibernate durable category complete the Component persistence layer,. In the business, specialized category is edited to manage Hibernate session, transaction processing and business services. And the component provides a service interface for external applications to use.5> Implementate the methods of the database resources granular access control.
