And Implementation Cloud Storage Management Mechanism Based On Teaching Characteristic

The revolution of teaching work in universities is toward to electronic, network-oriented direction with the rapid development of technologies. Teaching data means the cumulative data, which is the most important works of all teaching works in universities. Existing data manage systems are either method single or logic complexity, and saving historical data over years separately caused a lot waste of storage space.Researching of teaching data characteristic, combining advantage of cloud storage technology, implementation a cloud storage management system focused on teaching characteristics, manage teaching data more superiority and scientific, substantial increasing teaching works management more standards and efficiency. Dealing problems described above, mainly researched and analyzed teaching characteristic of historical teaching data. Implement of a cloud storage management mechanism, to meet the demand of massive data storage, the source date safe sharing and the requirements of high concurrent access.First, studying current systems, given a teaching characteristic model; given improved data mapping algorithm USSH; given a user management model optimized for teachers and students; given a caching algorithm LRUS to improve data management. Second, analyzed current data manage method, given a scalable system model based on cloud storage. Providing unified data R/W, share, log and access control service. Last implement manage system and test it. Test result ensure that models and structures can benefits data management of teaching characteristic, data caching algorithm sevenfold hit rate, respond request at ms level.
