Teaching Management Data Preservation Technology Research And Applications

This thesis analyzes both the characteristics of teaching management and the status of the data preservation technology. It studies the data preservation of teaching management from three aspects:the school requirements on the preservation of the data, the design targets and requirements of the preservation of teaching management data. It emphasizes on the characteristics and preservation needs of various data of teaching management, the data preservation needs in the basic process of the teaching management data and the standards of the safety design of the teaching management data. And especially in the aspect of the preservation of the data, this thesis puts forward some safety measures such as user authentication and access control, data backup, encryption and key management, digital signature and log management. It summarizes how to select the most effective data preservation technology, with consideration of the characteristics of the teaching management. In this way, the efficiency and safety of the data preservation are improved. In addition, in view of the safety problem in the security system for teaching management data, this paper brings up the concepts of data backup and vulnerability verification of the data security system. It suggests applying the methods to the technique for data security, providing the convenience for the system update and maintenance. This thesis further studies the security of data preservation from different angles such as the anti-counterfeiting, anti-tamper, anti-leakage and anti-repudiation. In the end, the thesis designs a system for teaching management. It tests the digital abstract algorithm and educed the test results. The thesis finally concludes the research and application of the preservation of teaching management data and its development tendency has been talked about.
