The structured life cycle method of software development divides the software life cycle into the planning phase, the development phase, and the operation phase.
Software life cycle, also known as software life cycle or system development life cycle, is the life cycle from software production to scrapping. During the cycle, there are problem definition, feasibility analysis, overall description, system design, coding, and debugging. and testing, acceptance and operation, maintenance and upgrade to abandonment and other stages. This time-based thinking method is an ideological principle in software engineering, that is, step-by-step and step-by-step advancement. Each stage must be defined, worked, and reviewed. , form documents for communication or reference to improve the quality of the software. However, as new object-oriented design methods and technologies mature, the guiding significance of software life cycle design methods is gradually decreasing.
Each cycle of the life cycle has certain tasks and produces documents (materials) of certain specifications, which are submitted to the next cycle as the basis for continuing work. According to the software life cycle, software development no longer only emphasizes "coding", but summarizes the entire process of software development. Software engineering requires that the start of each cycle of work can only be a continuation based on the "correct" results of the previous cycle; therefore, each cycle is a cycle of "activity-result-review-reactivity-until the result is correct" Progressing back and forth.
