The Analyses And Design Of A Network Information Management System Based On UML

Along with the development of information technology and domestic colleges' business expansion, information network is playing a more and more important role in the whole college administration. There's so great increase in the colleges' management workload that traditional ways of Info diffusion are no longer adapted to the new situation. Meanwhile, for the sake of effective information management, it's imperative to develop a colleges' network information management system. But to develop a network information management system is an extremely complicated system engineering. And to realize the system perfectly, we not only need a good way of software architectural design, but also track and monitor the process of software development constantly and effectively. To meet the requirement mentioned above, practice has shown that the most effective method is to adopt the Object-oriented UML modeling technique.UML is a standardized language that draws blueprint of software. It visualizes, describes in details, constitutes and documents the products of intensive system. It can describe various views that development process needs, based on which system is assembled. And UML provides different participants with the mechanism of availably sharing and communicating designing achievement. Besides, Object-oriented modeling technique can effectively control complexity and adapt varieties. It possesses highly flexibility and reusability with low risk, which increases the efficiency of development system. So the Object-oriented development method of UML is inevitable.This article takes the development process of network information management system of Software College for example. Aiming at the difficulties that baffle the web system development currently, we adopt the unified modeling language (UML) as system modeling tool, accelerating development process and improving the reliability of the system. We also tried an approach to requirement analysis of information systems based on RUP, specific to the problems which are often encountered during the requirement analysis of current information systems development process. We modeled business process through active images. We used sequence diagrams to construct system domain model. We also discussed the technique of business modeling, extraction and integration of used cases. Combined with UML illustrations, we specified how UML is applied in web software's analysis, design and modeling.Now this system has been put into operation. It has been proved that the study of this topic to accelerate system development speed, improve system reliability played a good role, to achieve the expected results.
