What is SDLC? The full name is Software Development Life Cycle. It also can be called Application Development Life-Cycle. These two names both use two words: life and cycle. SDLC shows a software’s whole life. It displays the starting from all development of softwares’ “birth”, after make use of these development of softwares, and until it loses its value go to “death”.
In general, all life cycles have five parts: Planning, Analysis, Design, Implementation, and Maintenance. Each part is relatively independent from each other as possible. In the same level, each parts’ nature is as similar as possible, the nature of the tasks of the same stage are similar as possible, thereby reducing the complexity of the parts in each level. It is beneficial to the software development process organization management to simplify different stage’s relation.
