The Research On The Application Of Integration Of Asynchronous Structure Database Technology In Education Administration System

Educational administration database is used primarily for depositing the needed data of the application layer. With the development of information technology, some education areas and schools have build their own database systems for their own control systems of Educational administration. However, because they have insufficient assorted with each other, each of the database system has its own standard, and this causes difficulties in the inter-linkage, intercommunication and the share of information. This thesis creates educational administration system by researching on the integration of asynchronous structure database technology, so that to realize the share of information between asynchronous structure database.The main work of the thesis is as follows:1) The thesis puts forward some questions of the integration of asynchronous structure database, and analyzes the synthesizing database system is consisted of different local databases, to realize the share of information and transparent accessing between the local databases.2) With the detail research works in the three methods: Data translating procedure, Middleware techniques and Multi-database systems, which can be used in the realization of integration of asynchronous structure database. Explicate all kinds of technical characteristic and effect in asynchronous structure database.3) The thesis gives the tentative scheme of integrating the educational administration system databases based on analyzing for requirement: adopting the method that combining the middleware technique with the multi-database technique. The whole skeleton uses multi-database technique and the contact between customer's machines and local databases adopts the middleware technique of database.4) The thesis realizes a middleware application procedure using the CORBA technique first. After that it processes the design of data translation in different database with the help of using PowerBuilder.Throgh coursing systerm, indicate adopt integration technology to realize the share of information in education administration system is possible.
