Rose是一种标准建模语言 (即UML) ,它利用用例图、静态图、行为图、交互图及实现图来表达建模思想 .文章简单介绍了UML及Rose的特点 ,并以设备台帐管理子系统为例 ,通过用Rose捕获用户需求、表达系统的对象和类之间的交互、描述系统的类及关联、添加系统中类的属性和操作以及用Rose生成类代码 ,阐述了用Rose建模火电厂设备状态检修管理信息系统的过程 .实践表明 ,Rose不失为一种强有力的建模工具 . Rose is a standard modeling language (UML) that expresses the modeling idea by using the use case diagram, static diagram, behavior diagram, interaction diagram and implementation diagram.The article briefly introduces the characteristics of UML and Rose, Management subsystem as an example, by Rose to capture user needs, the expression of the interaction between the system objects and classes, describe the system’s classes and associations, add system attributes and operations in the system and Rose generated class code, described Rose Modeling the process of managing the state information of the equipment of the thermal power plant, and practice shows that Rose is a powerful modeling tool.
