Design And Implementation Of Vehicle Rent Information System Based On J2EE

Business implementation goal of car rental company is to provide convenient car rental service for customers, thus to meet customers' various need for car. The development of car rental information system can guarantee business process ability from technical point. A certain car rental company is selected as research background in this dissertation, for the development of car rental information system, thus to meet actual requirement during business process.The research of car rental information system can be divided into three steps, which include requirement analysis, system design and system implementation. During requirement analysis step, main use cases that system should provide are analyzed. Sub use cases that included in every main use case are analyzed, and the relationship between use case and participant is analyzed too. Participants' use case requirements are described by UML use case diagram. Functions in system are analyzed, and the system is divided into several modules. System design includes database design, system conceptual design and system detail design. Database design obey the sequence of conceptual model design and relation model design, thus to acquire database table structure which can meet data storage requirement of every function. J2 EE is selected for system development, and the technical combination of JSP, Servlet, JDBC is used for system development circumstance establishment. The system is divided into three layers of View, Logic and DAO. Roles of every layer are determined, internal structure of every layer and layer coupling way are designed. Functions are detailed designed, flow chart model is established to describe function implementation process, functional classes and methods are designed too. During system implementation process, program code and user interfaces are implemented, and system running results are acquired. The system is comprehensively tested, system test result show that it attain system design requirement.The development of car rental information system provide information platform for car rental company, and enhanced business process ability.
