9 Break Down of UML Diagram Types UML diagrams are graphical representation of the elements and their relationships in a system. The visual representation of the system is considered the most important part of the entire process . Diagrams provide insight into a model (complete description of a system from a particular point of view). There are nine (9) diagram types available in the UML 1.x version: Class, Object, Use Case, Sequence, Collaboration, Activity, Statechart, Deployment, and Component diagrams. The UML 2.0 version thirteen (13) diagram types are divided under two main categories:
• Structural Diagrams: Class, Object, Component, Deployment, Package, Composite Structure.
• Behavioral Diagrams: Activity, Use Case, State Machine, Sequence, Communication, Timing, Interaction Overview.
Out of the thirteen (13) diagrams, the most widely used diagrams in the industry are use case, sequence, class, and state chart diagrams . A use case diagram is used to identify the system requirements and describe the activities within a system capturing the dynamics of the system’s operations. The diagram enables the identification of “actors” – human or automated systems that will interact with the system. Use-case diagrams can either represent the whole system or a sub-set of the system.
