Design And Implementation Of The Use Rights Management System Based On C / S Mode

The Permissions management system, which based on the user's permissions to determine the user how to use the information, is a new system. The goal is making the user must provide a fee to use those valuable network information by the classification of information, and making compensation for the use of information. In this paper, the popular techniques, form drawn by owner was used to increase the visual aesthetic effect of the system interface. The multi-threading technology and SOCKET communication technology were used in the permissions management system's design and implementation to meet the needs of multiple clients. In the current network environment, the system's design and implementation will provide some reference for the protection of intellectual property rights.The major work completed are as follows:1.The thesis analyzes the significance and research status of permissions management system, and combines with the special needs of enterprises, and abstracts the system's functional requirements to establish the system functional model.2. The thesis using SOCKET-based communication and multi-threading technology, designs the C / S model of permissions management system.3. The thesis combined with the demand for multi-terminal,analyses the various operations and data flow, and processes the system's data operations, and resolves the data's consistency, such as write-write conflict, read-write conflict, read-read sharing and so on. .4. In accordance with the requirements of modern software engineering, the paper for the system takes requirements analysis, preliminary design, logic design, database design and so on.5. The thesis abstracts the result of system analysis into specific functional classes, and implements permissions management system. In the process of realization, the client's forms are all painted by owner to increase the visual aesthetic effect of the system interface.6. A variety of tests were took for the permissions management system. The result shows that the system meets the needs of the initial study essentially, up to the scheduled requirements.7. At last, the thesis summarizes for the permissions management system, and analyzes the system's deficiencies and areas for improvement.
