Research And Design Of Highway Engineering Information Management System Based On J2EE

Recently, road constructions become the hotspot and keystone of investment for its huge social and economic benefits, In the powerful incline of investment, road constructions are developing incredibly. At the same time, the management during the process of road construction is still applying traditional manual method, which can not meet the requirements of actual complicated management, such as difficulty in project quality, controlling cost and the schedule. Therefore, it needs to design and exploit an information management system for road constructions.It is not difficult to realize an information management system, but what difficult is how to realize it in lest cost, and make it transplantable, maintainable and expansible. So, the point of this paper is providing a light level architecture which based on J2EE design, and implementing this information management system with this light architecture.Firstly, this paper introduce the thought of J2EE and analyze EJB component, the kernel component of J2EE and then point out the EJB component's insufficiency and maladjustment for medium and small information management system. In connection with the advanced design concepts, inversion of control (IoC) and Aspect Oriented Programming (AOP), author present a light WEB architecture, named ASH, which solves the popular problem in WEB system. Then according to the requirement of project, author divides this system into four subsystems depending on functional structure and gives the design of security subsystem and project management subsystem. During design process, object oriented method is adopted. Author has analyzed the system demand with use case diagram and flow chart, and also made data modeling for every entity of the whole system. Finally, this paper has described system realization under ASH architecture and analysis of project.
