What is a UML diagram?

A UML (Unified Modeling Language) diagram is a type of diagram that represents the structure and behavior of software systems. It typically includes classes, objects, relationships, and interactions.

UML diagrams are useful for a variety of purposes, including software development, system design, and documentation. They can help you visualize the structure of a system and understand how its components are connected.

When to use UML diagrams?

There are many situations in which UML diagrams can be useful. Some common uses of UML diagrams include:

Software development:UML diagrams can help you plan out the structure and design of your software, ensuring that all components interact seamlessly and efficiently.

System design: UML diagrams are often used in system design, as they can help designers visualize the structure of a system.

Documentation:A UML diagram can be useful for documentation, as it visually represents the structure and interactions of a system.
