In the past, I have read many articles about the top ten essential tools for developing common professional software such as. NET and. Net programmers. Today, I don't want to introduce these professional software. I want to introduce some auxiliary software that is often used during development to help us complete better development. I recommend commonly used a

The structure diagram proposed by Yourdon is another powerful tool for software structure design. A structure diagram is similar to a hierarchy diagram, and is also a graphical tool for describing software structures, in which a box represents a module with the name or main function of the module; the arrow (or line) between the boxes represents the calling relationship of the module. Because the formula is
