This time I pretended to be drawing on a grid (in fact, this is the built-in feature of many Computer-Aided System Engineering (CASE) tools ), then, you only need to draw boxes and lines like on the grid.

Currently, most popular UML modeling tools include Visio, Rational Rose, powerdesigner, and EA. They are basically enterprise-level software and have powerful functions. I have only used Visio, therefore, we will not introduce their features or similarities and differences. For more formal cases, examples are part of the project documentation. We recommend that you use the software listed above.When we encounter complicated tasks at workCodeIn logic o
