Design And Implementation Of Construction Cost Management Information System

With the great development of West China in full swing, the Midwest has formed a big investment, big development, complexity of construction project cost management project and the difficulty is more and more outstanding. Be imperative project construction management information system.The dissertation combined with the actual situation of our company, and the realization of the project cost management information system design. System C#.NET three layer architecture based development, has high repeatability and maintainability. The establishment of three tier architecture pattern database, reducing the number of connections to the database server. Since the validity check and business rules are in the middle layer of database application, so the business rules change, only need tochange to a middle tier server, do not need treatment in the client program, to a certain extent, improve the maintainability of the system. If the database needs to be replaced, as long as the data access layer data connection to modify it, also will not have an impact on other layer code, easy to maintain. Reusable properties of three layer architecture are very good. For the development of B/S application, for itsbusiness rules and data access work without RE development, for the Web server within the existing middle layer can be directly used.The dissertation analyzes database system and the application development platform based on component. System is in the realization of project management, the implementation phase of the project, project approval phase of the project cost management, project post evaluation, to achieve information management, improve the project cost management level, reduces the complexity of the project investment management, reduce project risk, through the application of this system will have great economic benefits.
