The E-business Model Based On CATV Wide Band The Research And Implement Of The Model Layer Of Center Platform

With the rapid development of digital and information technologies, it is an inevitable trend that the TV industry becomes more digitalized. The CATV network has become the new kind of wide band. On the basis of a special-endowed network program of Yunnan Technology Bureau-The Interact Open Service Platform of CATV, this paper is a part production of the distributed e-business TV supermarket using J2EE technology based on CATV network.The research methods applied in the paper are as follows:First: To analyze the actuality of the current CATV technologies, and to discuss its' future and develop tendency. Second: To research the current e-business model, and to discuss the e-business model that fit for CATV network. Third: To compare synthetically with the current technologies of program development, and take the J2EE technology as our basic technology of program development. Forth: According the feature of CATV network, to develop the TV supermarket that can run on the CATV network.The emphasis of this paper is to research how to apply design patterns, and to design and develop the model layer of distributed e-business platform with high performance and scalability based on CATV network. The core technology is EJB and DAO etc. in J2EE.Three main research results of the paper are as follows.First: Summarized the strongpoint and shortcoming, the affect to the system performance of the design patterns applied on the model layer.Second: Designed the model layer framework successfully, which has both scalability and reusability, based on CATV using design patterns.Third: Developed the model layer of the system using J2EE, implemented the function of every modules in the model layer. The reusability and the high performance of the modules improved the performance of the whole system.Aimed at the feature of the CATV network and the CATV users, this paper not only researched the basic framework of the distributed e-business system's model layer in theory, but also developed the system that has practicability. The model layer framework of the distributed e-business platform based on CATV network has some referenced value to develop the similar systems and has innovation and practicability.
