摘　　要：软件开发的主要目的是为用户的实际问题提供解决方案，UML的用例图用于确保开发过程是围绕这些问题进行的。标准的用例图使用一般的文字描述事务流中的一系列动作。这些描述非常详细，但是它们很难理解，尤其是面对复杂且繁多的用例时。该文介绍另一种方式，用UML的活动图描述用例的事务流。The core purpose of software development is to provide solutions to customers' real problems. Use cases are a vital aspect of a technique that has been used successfully to ensure that development projects actually focus on these problems. Using the 'standard' use-case form, these flows can be captured using plain English to describe sequential activities (see Figure 1). These descriptions are quite detailed, however, they can be difficult to decipher ——especially within a complex set of use-case scenarios. This article describes another way to capture these flows: By using unified modeling language (UML) activity diagrams.
