The Design And Development Of Basic Database Platform Of E-education In China

With the storm of informationization sweeping through the whole world,more and more investments are increasingly put in e-education by our nation.After nearly twenty years development,e-education has been fruitful.The Ministry of Education officially approved that strategic study base of Central China for e-education will be prepared and built by HuaZhong Normal University in March 17 this year,and the formal opening ceremony has been hold in April 13.As the first official research institutions in the field of e-education in our country,the establishment of "Strategic Study Base of e-education (Central China)" means that our nation’s e-education is stepping into a higher platform and the development of e-education is entering a stage of institutionalization, standardization and specialization.The purpose of this base is to build a "Think Tank" for e-education and its main duty includes the construction of index system, the acquisition and monitoring of data, trend forecasting and strategy enaction,etc.,so that it could provide policy support and continued guidance for the full range of study and development in the field of e-education. Against this background,this paper focuses on the designment and analysis of basic database system,aims to provide a set of key indicators for measuring the level of e-education’s development,and build a integrated e-education platform supporting public information, study and decision to meet different users’demand.The main work of this paper is as follows:(1)The first place is requirement analysis of e-education’s basic database platform.In this stage, theoretical analysis to database designment is carried out,which refers to users’demand,designing dimension,development conditions and theoretical foundation.(2)The second place is construction solution of e-education’s basic database platform.The organizational structure of database are described from four respects,which refers to basic education, higher education, vocational education and special investigation research,and index system of each aspect is demonstrated in detail.Then the following designment and development should be based on this research.(3)The third place is designment of database platform.In this stage,this paper presents the systemic design proposal, functional design proposal and database’s structure designment.The logic diagrams of business process is showed in systemic design proposal,the corresponding function meeting different users’demand will be designed in functional design proposal,and each related datasheet will be described and analyzed in database’s structure designment. (4)The last place is the development of basic database platform.In this part,this paper introduces the B/S three-tier architecture and working principles used in this system.The introduction on key technologies refers to site configuration and operate class.Then,parts of functions and some key implementation procedure in platform will be showed.In the end of paper, software testing and testing results will be given.
