英文答题
第一章(课本5)
类Class: abstract definition of a group of similar objects with the same data and the same operations
多态:Polymorphism
·By overriding the same-named operation of the parent class
Allow different subclass objects and parent class objects to receive the same message but provide different services
Classes at different levels share a behavior (the function name, parameters and return value
types are the same), but the behavior implementation is different
·Mechanism: dynamic binding or late binging
·Performance
Override parent class methods in subclass
Parent class reference points to subclass object Specific class overrides interface method Interface reference points to specific class object
Parent class reference points to child class object
Interface reference points to concrete class object
·Enhance flexibility, reduce information redundancy, and improve reusability and scalability
重载:Function overloading
In the same scope, several functions with different parameter characteristics use the same function name
Operator overloading
The same operator can be applied to different types of operands
Overloading mechanism
Static binding
When compiling a program, decide which implementation code of the function with the same name to use based on the number and type of function variables
Improve the flexibility and readability of 00 programs
第二章(课本6):
requirements engineering
actions: commiunication——> model differ from projects
建立根基
stakeholder 利益相关者 :对项目直接和间接贡献需求的人 协作需求收集=开会
UML Views and UML Diagrams:表达需求的工具 UNIT2 10
第三章(课本7)
基于场景、类、行为建模
1.基于场景
Use Case Diagram 要会画和详细描述 画用例图,用例详述
《include》包含关系
《extend》拓展关系
箭头往前指的是泛化关系
:Example1用例图如何描述?

From the aspect of actor:
1.there are 3 use cases combining to the Safehouse: “visit monitoring machine camera to connect the Internet”,“set system parameters”,“set alert”.
2.use case “visit monitoring machine camera to connect the Internet” combines to the camera.
sterotype 版型
箭头往前指需求 往后指代码
统一过程:用例驱动 用例:基于场景建模
Actor 参与者 使用软件的人
找Actor 和系统的交互,用例捕获交互 based on class diagram
对象图和类图的判断 UNIT2 17 静态快照 Class Diagram:UNIT2 14
如何判断一个图是对象图还是类图?
类图是抽象层次更高的模型,表示类及其关系;对象图是类图的实例化,表示系统在特定时刻的具体状态。
出现interface的肯定是类图,有函数的是类图
Example2类图:-
类间关系:Association,Generalization,Dependency,Realization

Classes and Interfaces:
- RegisterForm
- Attributes:
user
: UserDTOuserDao
: IUserDAO
- The
RegisterForm
class contains aUserDTO
object and anIUserDAO
interface. This class likely represents the user interaction registration form.
- Attributes:
- UserDTO
- Attributes:
userAccount
: StringuserPassword
: String
- Methods:
getUserAccount()
: StringsetUserAccount(String userAccount)
: voidgetUserPassword()
: StringsetUserPassword(String userPassword)
: void
- The
UserDTO
(Data Transfer Object) class is used to encapsulate user account and password information.
- Attributes:
- IUserDAO
- Methods:
addUser(UserDTO user)
: boolean
- The
IUserDAO
interface defines a method to add a user, which accepts aUserDTO
object and returns a boolean indicating success or failure.
- Methods:
Implementations of IUserDAO:
- SQLServerUserDAO
- Methods:
addUser(UserDTO user)
: boolean
- This class implements the
IUserDAO
interface for SQL Server database interactions.
- Methods:
- MySQLUserDAO
- Methods:
addUser(UserDTO user)
: boolean
- This class implements the
IUserDAO
interface for MySQL database interactions.
- Methods:
- OracleUserDAO
- Methods:
addUser(UserDTO user)
: boolean
- This class implements the
IUserDAO
interface for Oracle database interactions.
- Methods:
Relationships:
- The
RegisterForm
class has a composition relationship with theUserDTO
class (indicated by the filled diamond arrow) and an association relationship with theIUserDAO
interface. - The
UserDTO
class includes getter and setter methods for user account and password fields. - The
IUserDAO
interface is implemented bySQLServerUserDAO
,MySQLUserDAO
, andOracleUserDAO
(indicated by dashed lines with a triangle pointing to theIUserDAO
interface).
- RegisterForm
接口:1.通过接口实现设计类之间的可控链接
2.强调模块之间的可替换性
设计模式
行为建模 :状态图和顺序图
第四章(课本89)
设计过程:
1.显式 visible 功能上需求
2.隐式 invisible 非功能需求 NFR
设计概念 重构
内聚和耦合
目标是:高内聚低耦合(high cohesion and low coupling)
内聚指模块内各个元素的关系 耦合指模块与模块之间的关系
接口:接口划分:用户接口UI、 内接口、 外接口
体系结构:定义、重要性、决策
重要性:Why is architecture important?
1.Architecture provides a representation that facilitates communication among all stakeholders.
2.Architecture highlights early design decisions that willhave a profound impact on all SE work that follows, and
plays an important role in the success of the system as a runnable entity.
Architecture constitutes a relatively small model(a setof abstractions)of how the system components are structured and work together.
有利于各个stakeholder沟通需求
决策:早期决策对项目成功至关重要 风格:描述一个通用的类别 模式:描述局部**(一定是一组抽象类)**
Archetype 体系结构原型
相关题:what is an archetype?
第五章(课本10)
构建 面向对象 一组类
传统观点 构建模块——>函数function 设计原则 书本P203可控连接
第六章(12-15)
验证和确认的概念和区别
测试:
developer开发者 understand the system but,will test “gently” and is driven by “delivery”
independent tester独立测试组 understand the system too but, will attempt to “break” it
and, is driven by “quality”
确认测试 系统测试
单元测试 脚手架 驱动
白盒测试 基本路径测试(必考):
Example3:

黑盒测试
等价类划分法
面向对象测试
类:组织单元
类中操作:基本测试单元
孤立测试操作是没有意义的
