Software engineering Activities

Software engineering activities include "requirements, design, implementation, validation, and support", according to the engineering framework.

Demand

In general, we think of the "requirements" as a phase of software development.

In this phase, it mainly includes requirements acquisition, demand analysis and requirements verification activities.

The requirement analysis is mainly to determine the function, performance, data and interface of the software to be developed.

In particular, the following points can be made: (1) determine the comprehensive requirements of the software system, (2) analyze the data requirements of the software system, (3) derive the logical model of the system, (4) Revise the project Development Plan, (5) Develop a prototype system.

The process of software development

The process of software development is: requirements analysis, design, coding and testing.

Demand analysis: Not only user needs, should be encountered in the development of all the requirements. For example, you first need to know what to do with the project, what data should be entered in the test case ... In order to know these requirements clearly, you often have to communicate with customers, project managers, etc.

Design: Before coding, there must be a plan to tell you what to do, what the structure is, and so on. You must follow this, or it may be a mess.

Code: If your program cannot run or fail to reach the customer's requirements on the project deadline, you will not be able to get the money.

Test: The goal is to let you know when it's done. If you are smart, you should write the test first, so that you can know in time whether you are really finished. Otherwise, you often do not know what functions are really completed, and how far away from the expected target.
