| With the development of computer and Internet technology at present, paperlessoffice has increasingly become an informatized management solution modernenterprises must carry out. The study and design of transaction management system inthis paper provides technical support for the office automation of investmentcompanies.First, the hierarchical model of Java EE is introduced; second, the five categoriesof components of Java EE are roughly described. Through study of MVC designpattern, the design principles needed to comply with in the overall design process ofthis system are determined. Moreover, the characteristics, architecture, design ideaand usage of Structs, Spring and Hibernate frameworks are studied and understood.Second, a reasonable design scheme of the whole system is proposed. Accordingto the main functions of the system, the demand analysis of system function, systemperformance and system development environment is conducted, and the overallframework of the system is designed, the system is generally divided into four layers;outline design of the system is generally conducted from the module division ofsystem function, flow chart of system business, design of backstage database andother aspects, and a detailed design scheme is proposed. Finally, detailed design isconducted for main function modules of the system, and data flow diagram is givenfor corresponding module.Furthermore, the transaction management system is implemented based on SSHframework, the integration of Structs, Spring and Hibernate frameworks for specificimplementation of the system is given, finally the complete transaction datamanagement system is obtained. Meanwhile, the system is simply tested, and theresults of system implementation are introduced and illustrated from several modules of the system, including system login, staff management, main business process andassignment management of user rights.Finally, this paper is summarized, indicating the problems and future corrections. |
