What notations have you used? Can you tell more about UML?

In my practice, I have used several UML notations, most often class diagrams, sequence diagrams, and use case diagrams.

• Class diagrams help visualize the structure of the system, showing classes, their attributes, methods, and relationships.
• Sequence diagrams depict interactions between objects over time, which is useful for understanding the logic of functions and processes.
• Use case diagrams describe the functional requirements of the system from the user's perspective.

UML is a universal modeling language that helps system analysts and developers better understand and document the architecture and behavior of the system, facilitating communication between teams.
