Software

The eighth chapter focuses on the three models of object-oriented analysis: The function model (use case model), the static model of class and object representation (object model), the state diagram and the dynamic model (interaction model), which

The book "Software Engineering-theory, Method and practice" is mainly about the specific description of the specialty of software engineering.The first chapter, mainly introduces some basic concepts in software engineering, such as the concept of

This chapter uses a lot of knowledge of discrete mathematics. In a broad sense, formal methods are used to solve the problems in the field of software engineering, including the establishment of accurate mathematical models and the analysis

This chapter introduces the concept of software process. The goal of software engineering is to develop high-quality software at a defined time and budget, but this is a difficult thing to do. A large part of the failure of software projects is due

The structural design method is developed on the basis of modularization, top-down gradual refinement and structure-based programming technology.  Structured design methods can be divided into two categories, one is based on the data flow of the

The tenth chapter, the Software Test Foundation1, the basic principles of a, should be "early and continuous software testing" as a software developer's motto. B, programmers should avoid checking their own programs. C, in the design of test cases,

The Nineth chapter, the software realization1, the language compared to C + + program execution efficiency is generally higher than Java, the more complex things faster, but Java has a very powerful development tools, and overcome a lot of C + +

Software implementationSoftware implementations include basic activities such as code design, design review, code authoring, code walking, code compilation, and unit testing. In general, high-level languages are significantly better than machine and

11th chapter, Software evolution1. Basic features (1) Iteration: Software evolution drives continuous and continuous changes in software, and many activities are repeated at higher frequencies than traditional software development processes.(2)

The 8th chapter Object-oriented designAnalysis Model : Functional model, analytical object model, dynamic model.First, the concept of designDesign Activity Design is also a modeling activity, it is based on the analysis model to achieve the

Software implementation is a key process of software product from concept to entity. Code design, code-building, code-coding, design reviewThen it mainly explains the development experience of programming language and the superiority of advanced

Object-oriented designThe design activity divides into the system design and the detailed design and so on two main stages, for the complex system, reduces the complexity the effective method is the system modularization, namely has a complex

Object-Oriented AnalysisThe object-oriented analysis model is composed of functional model, analytical object model and dynamic model. In the Analysis object model, the analytic class is the content at the conceptual level, which is used to describe

The tenth chapter of software testing, but also I personally prefer a direction, software testing, although not involved in the code of irritability, but also contains a lot of technology, below I give you a brief introduction to the contents of

Formal methods in software engineeringThis chapter introduces the formal methods in software engineering, including sequential logic, Z language, Petri nets and so on.Software specifications are descriptions of software system objects, how objects

Microsoft's recent open positions:Job Title:principal Software Eng MgrWork Location:shanghai, ChinaJob Description:Is you a Linux, UNIX or FreeBSD ninja?   Think that those skills has no value at a company like Microsoft?   Think again! Come lead

The main introduction is verification and validation, software testing fundamentals, software testing strategies, software testing methods, object-oriented software testing and software testing tools.Error is the property of the software,cannot be

The main introduction is the programming language, software coding specifications, software coding case analysis and software code review.Software implementation is mainly in the software code part of the language, coding norms, code review and

This chapter describes the object-oriented design. Design is also a modeling activity. The design principles include modularization, coupling, cohesion, and reusability.Software design has several architectures. First, the warehouse architecture has
