Research Of Railway Business Reckoning System Based On J2EE Architecture

As a special department of China TieTong (CTT), Railway Business Department is responsible for providing railway communication service to the whole railway system of China. Railway communication business has various business types, flexible charge standards and multiple payment methods. In the past few years, the Railway Business Statistical Analysis (RBSA) system completes the management of railway business reckoning. However, with the development of railway business, current RBSA system is difficult to meet the needs of Railway Business Department. The target of this paper is to develop a new system with full functions and good expansibility for the Railway Business Department.By analyzing the RBSA system, a reckoning system solution based on J2EE architecture which aims at the work flow in Railway Business Department is figured out in this thesis. According to the solution, the system functions and database structure are designed, and an operation workflow of railway transportation communication business is modeled based on the Petri net. Finally, the functions of input, check and auditing for the railway transportation communication business data are implemented, and a data ensuring method that automatically undo mistaken operation according to operating log is put forward.
