Design And Implementation Of The Bus Route Query System For Hangzhou City Based On J2EE Technology

With the development of the Internet, the development of a city bus intelligent route query system is very necessary, more adaptable to the needs of modern society, so to speak. Bus route query system platform construction, is beneficial to promote the development of the modern transportation service industry, is an important service engine of future traffic development. Thesis mainly based on the J2 EE technology, design and development of the bus route query system.Firstly of all, the analysis of the software engineering subject, get business demand function description, based on the software development process, according to the actual situation of the bus route query, expounds the basic of the bus route query business demands, system architecture, the user use case status, according to the operation of the bus route query system and configuration environment, analyzes the technical features and operation of the software and indicators.Secondly, design the bus route query system, on the basis of the basic process is the software development project, the design of the system network architecture, the three level architecture of the system, is decomposed into each business module, then, gradually, respectively, the main business of the bus route query system UML design, design the sequence diagram, flow chart and state diagram of key elements, by UML design, detail design of the bus route query each main function modules, operation process, the software model. Make full use of the technology of J2 EE development, for the route and site query, management and so on function code design, development, operating main business processing module, the design includes: the user login interface, change to the query module, line site query module, query module, data management module, such as business functions, in the J2 EE environment, introduces the operation code editor page, page controls the design, the combination of the various modules and run, reflect the design core technology.Finally, test the system implementation on the function of the bus route query, basic functions correctly, reasonable design, its operation stability, higher accuracy of operation, has a good data access efficiency. Performance testing around the software running environment, focus on testing the software runs, the server’s CPU, memory utilization, and the average response time, test results, the system running normally each business use case, various operation parameters for software, comply with the design requirements and the software engineering standards.All in all, pay route query system platform construction, is beneficial to promote the development of the modern transportation service industry, is important in the development of future transportation service engine, effectively promote the bus route query efficiency, plays an important role. Through the design and implementation of the bus route query system, will continue to improve the bus route planning, and the bus route query and management of the business efficiency, has a certain practical value.
