系统用例 Vs.业务用例 [英] System use case Vs. Business use case

问题描述

我对分析和设计完全陌生......

I am completely new in analysis and design.....

请告诉我:

系统用例和业务用例有什么区别?

据我所知，UML中只有一种图叫做用例图.现在，他们呢?他们有单独的图表吗?

As far as I know, there is only one diagram in UML called use case diagram.. Now, what about them ? Do they have separate diagram?

来自维基百科:

业务用例在无技术术语将业务流程视为黑色框并描述业务流程由其业务参与者使用(外部的人或系统业务)以实现他们的目标(...)

A business use case is described in technology-free terminology which treats the business process as a black box and describes the business process that is used by its business actors (people or systems external to the business) to achieve their goals (...)

系统用例通常是在系统功能中描述级别(例如，创建凭证)并指定函数或系统提供的服务用户 (...)

A system use case is normally described at the system functionality level (for example, create voucher) and specifies the function or the service that the system provides for the user (...)

因此，简而言之，业务用例更多地是关于用户期望系统做什么，而系统用例更多地是关于系统实际做什么.

So, in short, business use cases are more about what the users expect the system to do, and system use cases are more about what the system actually does.
