graphs drawn in two different styles. The first one is complex and has no rules, while the second one is simple and well organized (although tedious ). Which one do you think is better? Most people will agree that the second one looks better, because although the two designs are functionally equal, the second arrangement is more neat. Figure 1 Figure 2 Figure 3 Avoid boxes of different sizes How can we improve Figure 1? First, make sure all the boxes are of the same size. A large box seems t

UML consists of nine diagrams, in which the core is the only---class diagram. Here is my summary of the Class Diagram section in UML. Class diagram is a static structure that shows the model, especially the classes that exist in the model, the internal structure of the clas

Objectiveclass diagrams and sequence diagrams are two of the most commonly used diagram in UML. I will make a detailed summary. In many books, or Web sites, when introducing the design of a subsystem of a system, many times, a simple class diagram is given to describe the relationship between the classes that make up the subsystem. This is sufficient to illustrat

Through the static diagram and behavior diagram introduced in previous blogs, we can use UML to describe the static structure and dynamic behavior of a system. At this time, we have alreadyGraphical representation of the entire structure of a typical Surface-to-face object system. At this point, the software development stage has reached the implementation s

first, the concept use case diagram (Diagram): Primarily used to describe the behavior of systems and the relationships between functions, is a graph that describes the relationship between participants (Actor) and use cases, and use cases and use cases.
