Station Dispatching Data Management System For Large-type Passenger Station

With the development of railway system modernization, it is urgent to construct a Station Dispatching Data Management System for Large-type Passenger Station in order to accelerate the railway' s information establishment and in order that information sharing technology brought by computer can be fully utilized.Based on the deeply study of the Smart Client architecture.this paper describes, the whole developing process in details from analysis, design to implemention of the Station Dispatching Data Management System for Large-type Passenger Station. Meanwhile, it introduced each functional module and some critical technologies in the developing process. The whole system includes using case diagram, class diagram, package diagram and data moduler which constructed by UML Tool.This paper focuses on the design pattern and framework, which are implemented in this system. It is based on layer architecture, combining with design pattern. The architecture solves the problems such as function redundancy, inconvenience of layer communication and tight coupling, and improves the system' s maintenance greatly , and also the ability to extend and transplant.This paper introduced the Optimistic Concurrency Control method to solve the concurrency problems of Station Dispatching Data Management System.Then this paper proposed to use interactive code generator to build a set of code of data access layer and present layer, which helps to improve the efficiency of developing.At last, this paper made a conclusion of the work that has done, bringing forward some insufficiency and envision of the research in the future.
