**Systems Analysis and Design** is a combination of three individual terms that have their meaning. The meaning of these terms is as follows,

**系统分析和设计**是三个具有各自含义的术语的组合。 这些术语的含义如下：

### 系统篇 **(**Systems**)** ###

A system is an organized group of components linked together to accomplish a specific objective according to a predefined plan. Every system has its goal; component of a system has its role but all components work together to achieve the desired goal of the system.

系统是链接在一起的组件的有组织的组，以根据预定义的计划实现特定的目标。 每个系统都有其目标。 系统的各个组件都有其作用，但是所有组件都可以协同工作以实现系统的预期目标。

For example- a computer is a system; its goal is to take data as an input; process it and gives the desired result/output. While keyboard, mouse, monitor, CPU, etc are the components of the computer system and the role of these components is different but all work together to achieve the main goal of the computer system.

例如，一台计算机就是一个系统； 其目标是将数据作为输入； 处理它，并给出所需的结果/输出。 尽管键盘，鼠标，显示器，CPU等是计算机系统的组成部分，并且这些组件的作用不同，但是所有这些组件协同工作以实现计算机系统的主要目标。

### 分析 **(**Analysis**)** ###

An analysis is a detailed inquiry about a particular problem. It enquires about the answers to all possible questions like what, why, when, how?An analysis is a detailed inquiry about a particular problem. It enquires about the answers to all possible questions like what, why, when, how?

分析是对特定问题的详细查询。 它询问所有可能问题的答案，例如什么，为什么，何时，如何？分析是对特定问题的详细询问。 它询问所有可能问题的答案，例如什么，为什么，何时，如何？

For example - if we have a problem and want to solve systematically than we will start from the point-like what is the problem?

例如-如果我们有问题并想要系统地解决，那么我们将从问题的角度出发，这是什么？

Is there any existing solution?

有没有现有的解决方案？

What will be a feasible solution?

什么是可行的解决方案？

How the problem will be solved efficiently?

如何有效解决问题？

An analysis is a systematic study/evaluation of data or information by splitting it into its parts to reveal its interrelations. The person who did analysis is known as an analyst. The analyst is an experienced and expert candidate who did the analysis.

分析是通过将数据或信息分解为各个部分以揭示其相互关系的系统研究/评估。 做分析的人称为分析师。 分析师是进行分析的经验丰富且专业的候选人。

### 设计 **(**Design**)** ###

It is a blueprint that describes the components and their relationship with a system. Before the implementation of a system, the system experts make its design which describes the internal and external layout of the system and describes the interdependency between the components of the system. There are two types of design,

它是描述组件及其与系统关系的蓝图。 在实施系统之前，系统专家会进行设计，该设计描述了系统的内部和外部布局，并描述了系统组件之间的相互依赖性。 有两种类型的设计，

1.  **Logical design** \- this design describes the abstract of a system.
    
    **逻辑设计** \-此设计描述了系统的抽象。
2.  **Physical design** \- this design relates to the system's processes i.e input, process, and output. It produces the working system by specifying the specification of the design which sets out exactly what the candidate system does.
    
    **物理设计** \-此设计与系统的过程有关，即输入，过程和输出。 它通过指定设计规范来产生工作系统，该规范明确列出了候选系统的功能。

**SAD is a systematic procedure to develop or redesign a system. Before developing a new system, the expert/executives did a detailed analysis.**

**SAD是开发或重新设计系统的系统程序。** **在开发新系统之前，专家/执行人员进行了详细的分析。**
