What software engineering is about, what software engineering is about

Software engineering is the study of engineering methods to build and maintain effective, practical, and high-quality software. It involves programming languages, databases, software development tools, system platforms, standards, design patterns, etc.

In modern society, software is used in many ways. Typical software such as email, embedded systems, human interfaces, office suites, operating systems, compilers, databases, games, etc. At the same time, almost all industries have the application of computer software, such as industry, agriculture, banking, aviation, ** sector, etc.

These applications promote economic and social development, improve people's work efficiency, and improve the quality of life.

Software engineers are a general term for people who create software using software, and software engineers can be divided into system analysts, software designers, system architects, programmers, testers, and so on. Programmers are also often used to refer to software engineers of all kinds.

Whether software development is a science or an engineering project has been debated for a long time. In fact, software development is a combination of both. But that doesn't mean they can be confused with each other.

Many people think that software engineering is based on computer science and information science, just as engineering in the traditional sense is to physics and chemistry.

In the United States, about 40% of software engineers have a degree in computer science. In the rest of the world, the ratio is similar. They don't necessarily use computer science on a daily basis, but they do use software engineering on a daily basis.

Software engineering is mainly about programming languages, databases, software development tools, system platforms, design patterns, etc.

Main disciplines: Marxist Theory, College Foreign Language, Advanced Mathematics, College Physics, Physics Experiment, Linear Algebra, Probability Theory and Mathematical Statistics, Programming Language, Data Structure, Discrete Mathematics, Operating System, Compilation Technology, Introduction to Software Engineering, Unified Modeling Language, Software Architecture, Software Requirements, Software Project Management.

In addition to the common basic courses, the major will also systematically study discrete mathematics, data structures, algorithm analysis, object-oriented programming, modern operating systems, database principles and implementation techniques, compilation principles, software engineering, software project management, computer security and other courses, and some other elective courses can be taken according to students' interests.

Practical links: graduation internship, curriculum design, computer engineering practice, production internship, graduation project (**).

The goals of software engineering are:

1) Applicability: the difficulty of the software to meet the user's needs under different system constraints.

2) Effectiveness: The software system can make the most efficient use of the time and space resources of the computer. All kinds of software regard the time and space cost of the system as an important technical indicator to measure the quality of software.

In many cases, there is a contradiction between temporal and spatial validity, and it is necessary to sacrifice temporal validity for spatial validity, or spatial validity for temporal validity. Space-time compromise is a technique often employed.

3) Modifiability: Allows modifications to be made to the system without increasing the complexity of the original system. It supports the debugging and maintenance of the software, which is a difficult goal to achieve.

4) Reliability: It can prevent the failure of the software system caused by the imperfection of concept, design and structure, and has the ability to recover the failure of the software system caused by improper operation.

5) Comprehensibility: The system has a clear structure that directly reflects the needs of the problem. Comprehensibility helps control system software complexity and supports maintenance, portability, or reuse of software.

6) Maintainability: After the software is delivered, it can be modified to correct latent errors, improve performance and other attributes, and adapt the software product to changes in the environment. Software maintenance costs account for a large proportion of software development costs.

Maintainability is a very important goal in software engineering.

8) Portability: The ease with which software can be moved from one computer system or environment to another.

9) Traceability: the ability to track software design and program forward according to software requirements, or reverse track software requirements according to software design and programs.

10) Interoperability: The ability of multiple software elements to communicate with each other and work together to accomplish tasks.

The main content of software engineering is software development technology and software engineering management. Software development technology includes software engineering methodology, software tools, and software development environment; Software Engineering Management encompasses the economics of software engineering and software management. The state attaches great importance to the development of the software industry and gives very preferential policies to the training of software talents.
