The Design And Implementation Of Online Education System Of Training School

The pervasion of network service makes more educational resource become available.More and more schools begin to use the electronic school-running system to decrease the operating cost.In this situation,it is so important to design an electronic school-running system which is full-featured and easy to use.The main contribution of this thesis is a newly proposed random algorithm of exam paper auto-generation.This algorithm is designed based on the bi-direction arrays for meeting the requirements of online exam module in the schooling-running system,which is customized for a training school.Firstly,this thesis analyzes several popular exam paper auto-generation algorithms,then uses the bi-direction array technology to avoid the problems coming from the duplicate random number.Through the tests with different scale item banks,we observe that the performance of newly proposed algorithm is not worse than the traditional random exam paper auto-generation in the small scale item bank,and superior to the traditional one in the middle and large scale item bank.Moreover,this paper as well designs a school-running system based on the proposed algorithm by using.NET,C#,and SQL Server 2005 in the Browser/Server way.After UML analysis of requirements and designing the database,the system is divided into function modules logically.Finally,a real implementation and evaluation on the designed school-running system is presented.The results show that all the performance and function requirements are met.
