摘 要

计算机软件建模技术现在越来越广泛的应用于软件工程中。本次基于BBS论坛系统建模设计的目的是为了在课程理论学习的同时，通过在一个实践的环境下，实际学习软件统一建模语言，对软件建模技术有一个更深的了解及认识。

同时利用建模工具对BBS论坛系统进行建模，用类图、用例图、时序图、协作图、状态图、活动图、组件图、配置图等面向对象分析设计的软件过程，以便让用户更好的理解。

关键词：学习；建模；理解

Abstract

Computer software modeling technology is now widely used insoftware

engineering. The modeling based on BBS forum system design is for the purpose of learning in the curriculum theory at the same time, through in a practical environment, the actual learning software, unified modeling language, understand and a deeper understanding of software modeling technology.

has also used the modeling tool of BBS forum system, analysis of software

processdesign using class diagram, use case diagram, sequence diagram,collaboration diagram, state diagram, activity diagram, component diagram, diagram, object oriented, in order to allow users to better understand.

Key words：Learning; modeling; understanding
