The diagram is drawn before the software developers or engineers start to code the system. The Unified Modeling Language is used in software development. The UML, abbreviated to Unified Modeling Language, is a general way of describing how the system structure would work, how it would work, how the object is connected, and the relationship between the objects. The seven types of behavioral UML diagrams are. In short, the behavioral UML diagram shows us the motion of the classes. What special event is causing the behavior? What will happen, or what will be the output of the user’s input. In what way the classes and their components are changing with time. The communication of objects, The movement of the data caused by the functions, objects, etc. How are the functions connecting different classes dynamically? It shows us how the classes, objects work, what a function does inside a class. The behavioral UML diagram illustrates the dynamic activity of the classes, objects, packages or modules, physical nodes, components, and interfaces. There are seven types of the Structural UML diagram.
It is also the architecture of the house. We see that there are walls, windows, doors, electrical components, plumbing, etc., in the design same goes with the structural UML diagram. This is like the architectural design of the building. Like how are the classes and other primary components are connected? The structural diagram illustrates the relationship between the classes, objects, packages or modules, physical nodes, components, and interfaces.
The structural UML diagram shows us the basic structure of the software system. The UML diagram falls into two categories.
