是流程图、用户界面还是什么?
Is it the flow diagram, User Interface or what?

在SDLC的设计阶段,重点通过系统建模来制定解决方案。执行 Uml 建模,称为统一建模语言。 UML建模有以下步骤:
UML建模基本上是为了定义问题,或者我们可以说它是解决问题的工具。

In the design phase of the SDLC, making solution is focused via system modeling. Uml modeling is performed which is called the Unified modeling language. UML modeling has the following steps
The UML modeling is basically for defining the problem or we can say it is a tool to solve the problem.

来自维基百科:
在系统中,详细描述了设计功能和操作,包括屏幕布局、业务规则、流程图和其他文档。此阶段的输出将新系统描述为模块或子系统的集合。
设计阶段将批准的需求文件中确定的需求作为其初始输入。对于每项要求,将通过访谈、研讨会和/或原型工作产生一组一个或多个设计元素。设计元素详细描述所需的软件功能,通常包括功能层次图、屏幕布局图、业务规则表、业务流程图、伪代码以及带有完整数据字典的完整实体关系图。这些设计元素旨在足够详细地描述软件,以便熟练的程序员可以用最少的额外输入来开发软件。

From wikipedia:
In systems, design functions and operations are described in detail, including screen layouts, business rules, process diagrams and other documentation. The output of this stage will describe the new system as a collection of modules or subsystems.
The design stage takes as its initial input the requirements identified in the approved requirements document. For each requirement, a set of one or more design elements will be produced as a result of interviews, workshops, and/or prototype efforts. Design elements describe the desired software features in detail, and generally include functional hierarchy diagrams, screen layout diagrams, tables of business rules, business process diagrams, pseudocode, and a complete entity-relationship diagram with a full data dictionary. These design elements are intended to describe the software in sufficient detail that skilled programmers may develop the software with minimal additional input.
