Telegram Application System Backstage Service Subsystem

which is one of the two clients in the entire telegram application system, is in charge of cognizance concrete service processing. It provides the functions of register, demonstration connection, contact surface disposition, service news correspondence, appendix transmission, text receiving and dispatching, user historic record inquiry and so on. The mainly users are the terminally quarter operators and the administrators.First, the first chapter talks about the practical using of the telegram terminal subsystem. At the same time, each module which was designed in view of the backstage service subsystem has carried on the simple definition and the description, and it has given the corresponding user interface design chart of symbols. The second chapter elaborates the backstage service subsystem software development in detail, and unifies the chart of symbols and the graph elaboration system overall construction. The second chapter elaborates exterior connection which backstage service subsystem relied on in detail, and makes the regulated design and the conceptive design for the MRB interface, the Database Interface and the Log Management. It also gives the definition of the Java interface class in detail. The third chapter proposes the method of realizing Data Model of the backstage service subsystem. When designing the data model, according to the characters of the backstage service subsystem, I designed the immediate news data sheet, telegram terminal data sheets, jurisdiction table, file transfer news table and so on. I've also made the detailed introduction and the explanation for each data sheet and the processing of developing data sheet with examples.With the foundation of the first three chapters, I have made the detailed description in view of backstage service subsystem function module programming in the fourth chapter. And propose the realization methods of each function module with the great length in detail in the ways of flow chart, realization showing and programming. Finally, the disposition information which involved in view of the telegraph office has been given the corresponding elaboration in the fifth chapter. I also give the explanation of each kind of terminology that mentioned in the article.Above all, the paper does carefully researching on the backstage service subsystem and gives the designing of each function module in detail, in order to consummate the backstage service subsystem and make sure of operating in normal.
