The Design And Implementation Of The Telecom ADSL Job-Ticket System Base On .NET

"Telecom ADSL Job-Ticket System" is a Telecom Operation Support System aiming at broadband data service, with its main function of configuration and management to ADSL data equipment. Such kind of software is now in the starting stage across the nation.During its developing process, we have attached great importance to improve its modifiability, expandability and maintainability..Net Platform is adopted as its developing platform..Net Platform is a new generation of computing and communicating platform, which provides overall object-oriented support, in the meantime, Web Service Technology has provided strong support to mutual visit between isomerism platforms.The system is confronted with a complicated application environment, to cope with different demands, a combined structure mode of B/S and C/S is adopted. In concrete words, B/S mode is utilized in the part of management and inquiry, C/S mode is utilized in the part of job-ticket analysis and equipment execution.In order to separate all predicable changes, modifications to the system should be as minor as possible when happening. N Layer Frame System which is very popular at present is adopted, that means program is divided into Data Layer, Data Access Layer, Business Logic Layer (Business Substance Type), Presentation Layer.Development course of the system has drawn upon from idea of Agile Software Development, which is strongly adaptive to changes of requirement.During the detail designing of system, Object-Oriented Design Pattern is used for program design. When there are changes, Refactoring is adopted to keep the code fitting in with the principle of object-oriented.For the sake of show the overall outlook of the system, each sub-system's function and database designing together with some system UIs are listed in the essay.The accomplishment of the whole system is a developing process of complete software system, involving many aspects in regard to programming and software project, and acquiring very strong generality and practicability.
