Research And Implementation Of Relevant Technology In Colleges And Universities Teaching Administration System

With the continuous development of information technology and the constantexpansion of colleges and universities scale and the lasting increases of teacher andstudent number， which more and more make colleges and universities teachingadministration system own the position holding the balance in the our country. In recentyears, the teaching management of colleges and universities is increasingly laborious andcomplex, and the existing colleges and universities teaching administration system hasbeen very difficult to meet the growing each kind of demand about it. Therefore, to adaptthe needs of large environment needs in modern colleges and universities teachingadministration structure of our country, adopting more advanced technology to thesystem’s function has become top priority, what is more, is able to lay a solid foundationfor safety, reliability, effectiveness and flexibility when the system runs.Firstly, in order to improve the flexibility of access control in colleges anduniversities teaching administration system, this paper deeply has analyzed and researchedsome existing data access control technologies about the system, and based on role-basedaccess control model, propose system-adaptive access control model to adaptively realizeuser’s authorization, thus, it simplifies users’ jobs of management and maintenance andproved practicable.Secondly, in order to meet the system’s real time requirement of data access control,we have deeply researched some existing data buffer technologies, and adopt thecache-network-based data buffer mechanism to this system, based on the analysis ofwhole pre-fetching and sequential pre-fetching for cached data, we propose a modifiedstrategy of pre-fetching cached data to improve the system’s caching mechanism andincrease its cache hit ratio, thereby which makes the system’s data access efficiencyenhance.Finally, through adopting the above-mentioned data access control technology anddata cache technology to colleges and universities teaching administration system, whichis able to make the system has higher use flexibility and data access real time, and provedthe system-adaptive access control model and the cache-network-based data buffer mechanism effective. Meanwhile, this paper makes clear the further studies in the futureabout the system’s access control technology and cache technology.
