Under Network Environment Engineering Project Management System Technology Research And Design

Abstract:With the wide application of Internet and the rapid development of related technologies, information management system gradually enters every field. The application of the company, enterprises and government institutions to the information technologies makes the management method undergo a fundamental change. With the increasing of the enterprise-scale and user demand, the number of projects is increasing constantly. It leads projects to change from simplification to integration and make the management of the project be out of control. At present, there are many problems as follows:huge amount of data in history is hard to manage, long cycle, wide range, various business, the efficiency of the management mode is bad. Therefore, it has a wide application prospect to develop a suitable project management information system with high quality and efficiency.This paper describes the features, business processes and advantages of the project management information system in the network. After analyzing the development method, the development mode is offered. After analyzing the whole process of the project, including the resources and business functions in the implementation of the project. The enterprise-class J2EE architecture with the features of the project information management system, the advantages of the multi-level framework is described and the overall structure of the project information management system is provided.Aims at the business process and characteristics of contemporary projects, the B/S stratification system is used to design the system and analyze its main function. The application of the related technologies in the J2EE system, as Java Servlet and JSP, we design the three levels as display, control and business logic. Combining the advantages of J2EE with the latest Internet technology, we design all kinds of system, mainly including the security of the system design, development platform design etc. Using the mapping mechanism of Hibernate, we design the relationship system in the PP and analyze the actual needs of persistence layer. The query method of the data storage layer is discussed and the conjunction layer structure in the database is designed on the basis of the above technologies. The paper designs all functions of the project information management system in the network in detail and gives the development process and implementation method of the system.
