For example , although the use - case diagram presented in 例如,虽然图2
Instead , they describe use - case diagrams and their components 相反地,这些篇幅用来描述用例图及其组件。
For requirements , prefer a line in a spreadsheet to a fancy use - case diagram 为了需要,宁可使用电子表格中的一行来描述,也不使用令人困惑的用例图。
Activity diagrams show the flow of control from one activity to the next , and use - case diagrams illustrate elements outside the system 动作图表显示从一个动作到下一个动作的控制流,使用案例图表说明系统外面的组成部分。
Business users , for example , can view use - case diagrams to see the business scenario overview and understand who ' s doing what , while developers can use class and object diagrams to get accurate descriptions of how to build those components into their code 譬如,商业用户可以观察使用案例的图表,以看清商业场景的概貌和了解谁在做什么事,而开发人员能使用种类和对象的图表来获得对如何把这些部件编进程序中的精确描述。
And the use - case diagram , state diagram and class diagram are used in uml diagram , which describe the software model from its function , logic and static structure . and the main arithmetic is shown . during the detail design process the com component technology is applied to envelop the logical part , hence to update and improve the software ; the software system of evaluation of the virtual prototype of the high power tf co2 laser is developed 本文采用面向对象的软件工程方法对高功率横流co _ 2激光器虚拟样机评价软件的需求进行了分析,并用uml中的用例图、状态图和类图分别从功能、逻辑和静态结构三个方面对软件模型进行了描述,提出了主要算法,在详细设计过程中应用com组件技术对其中逻辑部分进行封装,以便于升级和改进,开发了高功率横流co _ 2激光器的虚拟样机评价的软件系统。
