Research And Application Of System Model Based On UML

With the improvement of communication of society, the information technology has spread into every fields of modern society. And as the core of the information technology, software is considered more and more important. In a new economic circumstance, the consumer and enterprise now appeal to software much more functions, such as capability of system, adaptability, reliability, reuse, and this kind of change is a challenge to software. Nowadays, in order to meet the needs of rapid and efficient development, traditional method of software development has to establish a better environment and apply more reusable modules. System model emerges as the times require.This paper is about the research in the characteristics of the data and functions in information systems. It tells of how to build a reusable, expansible and reliable system model with experiences on some well-built system and how to use this system model to make a project evolve rapidly and efficiently.During the research of system model, data model and function model is the two keys. This paper discusses the whole process of system model building, including the requirement, analysis, design, realization and application, and indicates the characteristics and support of the system model building.
