Design And Implementation Of Software Project Management Tool Based On The Three-tier Structure

A summary about current project management tools is given based on the development and study of software project management information system. A simple and useful tool of software project managent has been developed with Delphi and three-tier structure. First, the main contents of software project management are analyzed and then the project targets and functions of this system are put forward in this paper; Next, the process, strategy and methods of cost estimation are studied and based on COCOMO model a better COCOMO model has been presented considering code reuse. Moreover the function of software cost estimation module has been implemented; Then some detailed solutions to the structure of this system are given, furthermore the characteristics of the component object model are analyzed in the paper; Finally, some other problems in the software development process has been analyzed and correlative solutions to these problems are represented in the paper.The keystone of the paper is to carry out a tool of software project management. Three_tier distributied architecture based on component object model is the key of this system. This system is perfectly run and it is useful to make a criterion of application flow, improve application efficiency and cut down the application cost.
