软件工程的概述：软件工程就是为了经济地获得可靠的且能在实际机器上有效地运行的软件，而建立和使用完善的工程原理。Software engineering is to establish and use sound engineering principles in order to economically obtain reliable software that can run effectively on actual machines.

软件工程是指计算机软件开发和维护的一门工程学科。

Software engineering refers to an engineering discipline of computer software development and maintenance.

采用工程的概念、原理、技术和方法来开发和维护软件， 把经过时间考验而证明正确的管理技术和当前能够得到的最好技术结合起来，以经济地开发出高质量的软件并有效地维护它，这就是软件工程。

Use engineering concepts, principles, techniques and methods to develop and maintain software, and combine time-tested management techniques with the best techniques currently available to develop high-quality software economically and maintain them effectively It, this is software engineering.

软件工程的目标是运用先进的软件开发技术和管理方法来提高软件的质量和生产率。

The goal of software engineering is to use advanced software development techniques and management methods to improve software quality and productivity.

以较短的周期、较低的成本生产出高质量的软件产品，并最终实现软件的工业化生产 。

Produce high-quality software products with a shorter cycle and lower cost, and finally realize the industrialized production of software.

软件工程的目标是正确性、可靠性、可维护性、可重用性、可追踪性、可移植性、可互操作性、有效性。The goals of software engineering are correctness, reliability, maintainability, reusability, traceability, portability, interoperability, and effectiveness.

软件工程的原则是抽象、模块化、信息隐藏、局部化、一致性、完全性、可验证性、实践经验的总结。The principles of software engineering are abstraction, modularity, information hiding, localization, consistency, completeness, verifiability, and the summary of practical experience.

软件生存周期模型：

瀑布模型

瀑布模型的主要思想是软件开发过程与软件生命周期是一致的，相邻两个阶段之间存在因果关系，需要对阶段性产品进行评审 。The main idea of the waterfall model is that the software development process is consistent with the software life cycle, and there is a causal relationship between two adjacent stages, and the phased products need to be reviewed.

瀑布模型在软件工程中占有重要的地位 。瀑布模型上一阶段的变换结果是下一阶段的变换的输入，相邻两个阶段具 有因果关系，紧密相联 。The waterfall model occupies an important position in software engineering. The transformation result of the previous stage of the waterfall model is the input of the transformation of the next stage. The two adjacent stages have a causal relationship and are closely connected.

瀑布模型的不足是缺乏灵活性，到最后阶段才能得到可运行的软件版本 。The disadvantage of the waterfall model is its lack of flexibility, and a runnable software version can only be obtained at the final stage.

快速原型

快速原型模型的优点是有助于获取用户需求，加强对需求的理解，尽早发现软件中的错误，支持需求的动态变化，适合于需求动态变化，事先难以确定系统 。The advantage of the rapid prototyping model is that it helps to obtain user requirements, strengthen the understanding of requirements, find errors in the software as soon as possible, support dynamic changes in requirements, and is suitable for dynamic changes in requirements. It is difficult to determine the system in advance.

快速原型模型的不足是不能支持风险分析。The shortcoming of the rapid prototyping model is that it cannot support risk analysis.

螺旋模型

螺旋模型是瀑布模型、原型模型的有机结合，同时增加了风险分析。 The spiral model is an organic combination of the waterfall model and the prototype model, while adding risk analysis.

螺旋模型的优点是有助于获取用户需求，加强对需求的理解，尽早发现软件中的错误，支持需求的动态变化，支持风险分析，可降低或者消除软件开发风险，适合于需求动态变化，事先难以确定并且开发风险较大的系统 。The advantage of the spiral model is to help acquire user needs, strengthen understanding of requirements, find errors in software as early as possible, support dynamic changes in requirements, support risk analysis, and reduce or eliminate software development risks. It is suitable for dynamic changes in requirements. It is difficult to identify and develop a risky system.

ANSWER: D

Cohesion refers to what the modules will do. Low cohesion would mean that the module does a great variety of actions and is not focused on what it should do. High cohesion would then mean that the module is focused on what it should be doing. Rank the following types of Cohesion, in order of worst to the best.内聚是指模块将做什么。低内聚意味着模块执行各种各样的操作，而不是专注于它应该做什么。高内聚意味着模块专注于它应该做的事情。按照从最差到最好的顺序对以下类型的内聚进行排名。

Coincidental cohesion.

Coincidental cohesion is when parts of a module are grouped arbitrarily; the only relationship between the parts is that they have been grouped together (e.g. a "Utilities” class).

巧合内聚

巧合内聚是指模块的各个部分被任意分组；部件之间的唯一关系是它们已组合在一起（例如“实用程序”类）。

Logical cohesion.

Logical cohesion is when parts of a module are grouped because they are logically categorized to do the same thing even though they are different by nature (e.g. grouping all mouse and keyboard input handling routines).

逻辑内聚

逻辑内聚是指模块的各个部分被分组，因为它们在逻辑上被归类为做同样的事情，即使它们本质上是不同的（例如，对所有鼠标和键盘输入处理例程进行分组）。

Temporal cohesion.

Temporal cohesion is when parts of a module are grouped by when they are processed - the parts are processed at a particular time in program execution (e.g. a function which is called after catching an exception which closes open files, creates an error log, and notifies the user).

时间内聚

时间内聚是指模块的各个部分按它们的处理时间分组——这些部分在程序执行的特定时间进行处理（例如，在捕获关闭打开文件的异常后调用的函数，创建错误日志，并通知用户）。

Procedural cohesion.

Procedural cohesion is when parts of a module are grouped because they always follow a certain sequence of execution (e.g. a function which checks file permissions and then opens the file).

程序内聚

程序内聚是指模块的各个部分被分组，因为它们始终遵循特定的执行顺序（例如，检查文件权限然后打开文件的函数）。

Communicational / informational cohesion.

Communicational cohesion is when parts of a module are grouped because they operate on the same data (e.g. a module which operates on the same record of information).

通信内聚

通信内聚是指模块的各个部分由于对相同的数据进行操作而被分组（例如，对相同的信息记录进行操作的模块）。

Sequential cohesion.

Sequential cohesion is when parts of a module are grouped because the output from one part is the input to another part like an assembly line (e.g. a function which reads data from a file and processes the data).

顺序内聚

顺序内聚是指模块的各个部分被分组，因为一个部分的输出是另一部分的输入，如装配线（例如，从文件中读取数据并处理数据的函数）。

Functional cohesion.

Functional cohesion is when parts of a module are grouped because they all contribute to a single well-defined task of the module (e.g. Lexical analysis of an XML string).

功能内聚

功能内聚是指模块的各个部分被分组，因为它们都有助于模块的单个明确定义的任务（例如 XML 字符串的词法分析）。

Coupling refers to how related are two modules and how dependent they are on each other. Being low coupling would mean that changing something major in one should not affect the other. High coupling would make your code difficult to make changes as well as to maintain it, as modules are coupled closely together, making a change could mean an entire system revamp. Rank the following types of coupling, in order of highest to lowest coupling,耦合是指两个模块之间的关联程度以及它们之间的依赖程度。 低耦合意味着改变一个主要的东西不应该影响另一个。 高耦合会使您的代码难以进行更改和维护，因为模块紧密耦合在一起，进行更改可能意味着整个系统的改造。 对以下类型的耦合进行排序，按照耦合从高到低的顺序，

Content coupling.

Content coupling (also known as Pathological coupling) occurs when one module modifies or relies on the internal workings of another module (e.g., accessing local data of another module).Therefore changing the way the second module produces data (location, type, timing) will lead to changing the dependent module.内容耦合。当一个模块修改或依赖另一个模块的内部工作（例如访问另一个模块的本地数据）时，就会发生内容耦合（也称为病理耦合）。因此改变了第二个模块产生数据的方式（位置、类型、时间） 将导致更改依赖模块。

Common coupling.

Common coupling (also known as Global coupling) occurs when two modules share the same global data (e.g., a global variable). Changing the shared resource implies changing all the modules using it.公共耦合，当两个模块共享相同的全局数据（例如，一个全局变量）时，就会发生公共耦合（也称为全局耦合）。 更改共享资源意味着更改所有使用它的模块。

External coupling.

External coupling occurs when two modules share an externally imposed data format, communication protocol, or device interface. This is basically related to the communication to external tools and devices.外部耦合，当两个模块共享外部强加的数据格式、通信协议或设备接口时，就会发生外部耦合。 这基本上与与外部工具和设备的通信有关。

Control coupling.

Control coupling is one module controlling the flow of another, by passing it information on what to do (e.g., passing a what-to-do flag).控制耦合是一个模块控制另一个模块的流程，通过向它传递关于做什么的信息（例如，传递一个做什么标志）。

标记耦合 (Stamp Coupling) ：带有数据结构的数据参数

Stamp coupling occurs when modules share a composite data structure and use only a part of it, possibly a different part (e.g., passing a whole record to a function that only needs one field of it).This may lead to changing the way a module reads a record because a field that the module does not need has been modified.当模块共享一个复合数据结构并且只使用它的一部分，可能是不同的部分（例如，将整个记录传递给只需要其中一个字段的函数）时，就会发生标记耦合。这可能会导致改变模块的方式 读取记录，因为模块不需要的字段已被修改。

Data coupling.

Data coupling occurs when modules share data through, for example, parameters. Each datum is an elementary piece, and these are the only data shared (e.g., passing an integer to a function that computes a square root).数据耦合，当模块通过例如参数共享数据时，就会发生数据耦合。 每个数据都是一个基本部分，这些是唯一共享的数据（例如，将整数传递给计算平方根的函数）。

Message coupling.

This is the loosest type of coupling. It can be achieved by state decentralization (as in objects) and component communication is done via parameters or message passing (see Message passing).这是最松散的耦合类型。 它可以通过状态分散（如在对象中）来实现，组件通信是通过参数或消息传递完成的（请参阅消息传递）。
