Design And Implementation Of J2EE-based Highway Toll Management System

As a modern transporting way, highway is playing an increasingly important role in economy society now. Because of high speed, large capacity, low transportation costs and safety, etc., highway can effectively reduce operating costs, reduce running mileage and become communicating ties among different regional economic.Highway has played an important role to improve the competitiveness of enterprises, economic development and social progress. Based on the analysis of existing highway toll systems, this essay analyzes the actual needs and business processes of highway toll system, using J2 EE solution to implement the highway toll system.According to the life cycle theory of software, the reserch of this subject includes requirement analysis, design, development and testing of systerm,which is completed by mode of MVC and Web technology like JSP, Servlet and so on. Firstly, this essay describes the background of project and the main problems of highway toll system, using the means of drawing UML cases and flowcharts to analyze the functional requirements and non-functional requirements of the system. Secondly, this essay designes the system architecture with clear principles and objectives, meanwhile, his essay designes logical and physical architecture of the system. At the same time,using a flow chart to describe the overall business process. Finally, this essay adopts the core function module by using a modular approach and determines to use J2 EE technology solution to implement the system. Next,we design the functional modules of the system in detail, using UML dynamic map to design core function modules with focusing on the definition of system classes including boundary type, control type, interaction type between entity classes and message flow.At the last,we design the structure and mthd of splitting data rates of vehicular accounts.Finally, we use both a functional and a performance testing to make sure the system can work well, the main testing method is "black box", the main target is to test whether system can work properly, including the system interface, the handle of business processes, page response time, and the effectiveness of concurrent access, through the recording and analysis of test results, we have found that functionality and performance of the system has reached the desired value.
