Class Diagram

class

Diagram illustrates the structure of a system by showing the classes of the system, their attributes, methods, and relationships between them

  • Depicts the static structure of a system
  • Shows the relationships and dependencies among classes
  • Can be used for both high-level system design and detailed modeling of software components
