| The thesis is concentrated on systematism and conclusion of relevant technical applied during the development of net manage system of a teacher in charge of class in a TV & Broadcasting university. At first advantage of application of JAVA technical for development of WEB application system is emphasized, the characteristic of block construction of MVC mode, the advantage of JSF block and the relevant key technical are described. Secondly the technical function, realization and running environment of distribution module of EJB is researched in principle, which is the basis of the application of EJB module used in second part of the thesis. Thirdly, after analysis of technical performance of connect to a database, a strategy of that is adopted, i.e database connection pool technical is used in system together with a new technical, namely mechanism of offline buffer data set .The performance and capability of the system are enhanced obviously. An important feature of the system the application of database technical, e.g. a serial of triggers are supplemented during the design and realization of the database, a part of function of application system are performed directly inside the database, the complex of development of application system and the transmission of data to background are reduced, as a result of it the load of application system is reduced. EJB module plays an important role in the J2EE construction and is applied as data access module in the system after theory analysis and practical application of EJB development technical, the load of application lay is reduced and the flexibility and throughput of system are improved obviously... |
