Digital Tv User Management System To Achieve

Digital Television Subscriber Management System (DTVSMS) is the Information Management System oriented to Community Antenna Television Subscriber to realize the agendum and transaction management. The system can support the procession of the business for the DTV, realize the complete business management, and provide detailed statistics and analysis, decision-making and standardized system interface.This paper used Windows 2000 Server as the system platform and SQL Server 2000 as the Database System. The DTVSMS is programmed via Java, using ODBC, RMI, Multi-Threading, Socket, Swing Components etc, which included Subscriber Management Module, Product Management Module, Device Management Module, Authorization Management Module, Message Management Module, System Management Module, Right Management Module etc.The introduction and the state of art for the DTVSMS were given and the main problems which should be solved were talked about. We also talked about the target, design rules, system architecture and system function modules, and analyzed the core business, user interface design, system interfaces. Also the techniques were provided.Here are the key problems:First, on the basis of the distribution techniques and component techniques, the information system was divided into three blocks: representation logic, business logic, and data management. The RMI techniques in Java were used to realize the three-tier architecture and distribution application.Second, with the extendible design concepts, the generalization and flexibility was demonstrated via the design of the business procession classes and interfaces.Third, according to the business procession of the subscribers' buying products, transaction policies' flexibly specifying, business glides' exclusively recording, timely procession of the services are core business.Fourth, using the Swing components techniques, the user interface guidelines are kept consistent, which facilitate the users' operations.
