What processes are included in the software development steps?

Software development usually includes the following main steps and processes:

1. requirement analysis: define the objectives of software development, communicate with customers or relevant stakeholders, collect and analyze the requirements of the project. This step focuses on determining the problems to be solved and the functions provided by the software.

2. Design: On the basis of demand analysis, design the system. Including software architecture design, module design, database design, etc. To ensure that the software can meet the requirements and is easy to maintain and expand.

3. Coding: according to the documents and specifications in the design stage, the actual coding work is carried out. Developers use programming languages to turn designs into executable software programs.

4. Test: Test the written code, including unit test, integration test and system test. The purpose is to ensure that the software can run normally at all levels and meet the requirements of design and demand.

5. Deployment: Deploy the software to the target environment so that users or customers can start using it. This may involve installation, configuration, data migration and other processes.

6. Maintenance and support: Once the software is online, it needs to be maintained, including fixing known problems, providing technical support and updating the version. To ensure the stable and continuous operation of the software.

These steps usually follow the waterfall model, that is, they are completed in turn. However, modern software development also adopts agile and iterative methods, in which the development team can shuttle back and forth between different stages more flexibly to better cope with changes and the continuous evolution of customer needs.
