| Combine the status of higher education self-study examination's information management and the audit's features of self-examination's graduate-qualifications, design an online auditing system to simplify the complexity of auditing and reduce the workload of management, and the self-study examination's staff at all levels can collaborative use the system in future period. And it is a great significance in the promotion of higher education self-study examination's standardization.This paper analyses the technology of Web services and role-based access control, discusses the Web services architecture and authentication, and also compares role-based access control technology with the traditional access control technology. On this basis, designs work processes and main functions for the consumer's requirement. And also describes the division of main modules in plan-input subsystem, candidate-register subsystem and auditing subsystem.On the basis of overall design of system, pivotal functional modules of the system are described. Construct a database connection pool and control the abnormity of the connection pool's non-normal disconnection. Analyses the providers and visitors of Web service in the system, and also describe the realization of Web service, on the basis of these design a Web service authentication. According to the characteristics of the user-management in auditing subsystem, contact the authority with the role's domain on the basis of authority and role in order to visit the corresponding data in the database by domain information.It is shown by the results of actual operation that the system can ensure the staff at all levels to share information and work in cooperate, and also can ensure the effective real-time access to database in different networks environment, the system can manage the users flexibly in addition. The system is easy to expand, maintain and use, it is worthy to practice. |
