Software development process refers to the general process of software development and design, including the overall structure of software, module composition, functional design, program compilation, debugging, debugging, testing and other processes.
Main steps:
Project analysis, development, demand analysis, design, programming, software testing, software delivery, acceptance and maintenance.
Explain in detail:
The process of software development is a general process of software design ideas and methods, which includes a series of operations such as analyzing the requirements of software, designing the functions, algorithms and methods of software, designing the overall structure and modules of software, coding and debugging, debugging programs, writing and submitting programs, etc. Meet customers' needs and solve their problems. If there is a higher demand, the software needs to be maintained, upgraded and scrapped.
Eight steps in the software development process:
1. The first process of software development is the analysis and determination of project development. Mainly after the completion of the project development determined by the software developer, it is necessary to discuss with the demander to determine the objectives and specific requirements of the demander's software development.
2. The next step is demand analysis. This step is also the stage to determine the specific ideas for normal implementation of software development. After software development is confirmed, the software functions that customers need to realize are analyzed in detail. At the same time, we should consider the possible changes in the development process, make a demand change plan, and respond to special circumstances at any time to ensure the smooth progress of the software development process.
3. The next step is software design. According to the analysis results of software functional requirements in the previous stage, the design involves software design framework, software system module and software system database, which is mainly divided into two parts: overall design and detailed design.
4. The next step is the implementation steps of programming. Programming is also based on software design, and all parts of software design are realized by computer program code. Programming adopts unified and standardized programming rules to ensure the understandability of software programs.
5. The next step is software testing. That is, the client software is also a software program after it is implemented with programming code according to the design. After the completion, it is necessary to modify the written program to form an overall framework. These functions are unit, assembly, system testing, the correctness of the program and the adequacy of the functions required by customers to determine whether the software meets the development requirements. This is also a process of finding problems and correcting them.
6. Complete the software development through the above core links. Next, after the software development is completed, the software system is handed over to the customer to meet the customer's requirements, and the software installation program, database data dictionary, user installation manual, user guide, demand report, design report, test report and other documents are delivered to the customer to guide the customer to install the software and installation skills.
Remind customers to pay attention to the running state of the software, the environment, the detection and precautions of the server and related middleware, understand the actual operation method and use process of the customer's software, and realize the tasks stipulated in the contract.
7. After the user accepts the software development delivered by the development, the user actually runs the test. After satisfactory results are obtained, the developed software is checked and accepted.
8. Customized software usually needs to provide after-sales service, maintain the software, or modify the application software program according to the new needs of users, so as to continuously meet the actual needs of customers.
