The UML Class diagram is a graphical notation used to construct and visualize object oriented systems. A class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s: classes,and the relationships among objects.

What is the purpose of UML diagrams?
UML diagrams can be used as a way to visualize a project before it takes place or as documentation for a project afterward. But the overall goal of UML diagrams is to allow teams to visualize how a project is or will be working, and they can be used in any field, not just software engineering.

UML, Unified Modeling Language, is a standard notation for the modeling of real-world objects as a first step in developing an object oriented program. It describes one consistent language for specifying, visualizing, constructing and documenting the artifacts of software systems.
What is structural UML diagram?
UML Structural diagrams depict the elements of a system that are independent of time and that convey the concepts of a system and how they relate to each other. The elements in these diagrams resemble the nouns in a natural language, and the relationships that connect them are structural or semantic relationships.
