Abstract


As we all know, the actual engineering construction development is difficult, the documents are complex, and it contains many variables. The enterprise infrastructure project management system using computer information technology at the entire life cycle of project management, ensure realization of the project in the construction goal at the same time, greatly enhancing the project scientific management level.This system incorporates the international advanced project management ideas and methodology, using the earned value principle as the basis of project management model, through the establishment of breakdown structure WBS recently, especially to the project process realize cost/schedule analysis and control. This system combined with the actual situation of enterprise project management, relying on years of successful experience, using specialized software design ideas and the framework of advanced J2EE technology, combining present on relatively popular open-source framework Spring、Struts and Hibernate, with J2EE Web application of lightweight solution, building a clear structure, reusability, maintenance convenient Web applications in the short term . It is the best solution for owner project management mode.This thesis analyses the enterprise infrastructure project management status and working characteristics, taking the actual application as the core, Oracle database system as system of data development platform, using j2ee technology and an object-oriented programming language Java with more popular nowadays, use the B/S system development mode, integration suitable for the development of the enterprise infrastructure project management features of a set of software.System takes three-layer structure based on J2EE architecture, which are the presentation layer, business logic layer and data storage layers.We take the MVC framework design idea and method, through the integration of SSH frame, making the program structure clearly, each layer function clear, and reducing the program’s coupling. Tnteracting with the database , we use the DAO database design pattern to abstract and encapsulate all data source visit, separating logic and database access logic. Through the use of Tomcat database connection pool database connection technology to improve the efficiency of frequently, changing the past on the operation of database connection and disconnection. This system has been through test, and puting to use in practical projects, show that the system can improve enterprise construction project management of automation level, ensure the accuracy of the information, data security and unity. In the end, system future improvement is prospected.
