Software Engineering Overview

Software Engineering definition: use modern scientific and technical knowledge to design and construct computer programs and relevant documents necessary for the development, operation, and maintenance of these programs.

From the perspective of the development of software development, software engineering does not come along with the emergence of software development, and a seriesCrisis, such:

1. The product does not meet your actual needs.

2. The speed of improving the production efficiency of software development is far from meeting objective needs.

3. Poor Software Product Quality

4. Estimation of software development costs and progress is often inaccurate

5. Software Documents are usually incomplete or unqualified

6. Expensive software

It is precisely because these crises have not been solved that we have proposed the concept of software engineering. As a result, software engineering has developed into a series of independent disciplines.

Chapter 1 focuses on the transition from software to software engineering. The subsequent chapters are the corresponding introductions of various stages of software development (this is the context of the entire tutorial)

The development process is as follows:

 The software is introduced as follows:

The software engineering introduction is as follows:

The following sections describe the phases of the software engineering process in sequence.
