UML Diagram Types List
Types of UML Diagrams
Unified Modeling Language (UML) is a language of graphic description for object modeling in the field of software engineering. UML was created for definition, visualization, designing of software systems. UML is an open standard that uses graphic notations for creating visual models of object-oriented software systems.
Two types of diagrams are used in UML: Structure Diagrams and Behavior Diagrams. Behavior Diagrams represent the processes proceeding in a modeled environment. Structure Diagrams represent the elements that compose the system.
There are seven types of Structure Diagrams that must be present in any modeled system:
- Class Diagram
- Component Diagram
- Composite Structure
- Deployment Diagram
- Object Diagram
- Package Diagram
The Behavior Diagrams group includes:

Video 1. Types of UML Diagrams
UML Class Diagram is a type of Structure Diagrams that shows the classes of a system, attributes, operations, and the relationships between them.
UML Package Diagram is a type of Structure Diagrams that represents the packages of the model and dependencies between them.
UML Object Diagram is a type of Structure Diagrams that shows the objects of the system and attributes, and relations between the objects at a certain moment of time.
Use Case Diagrams
UML Use Case Diagram is a type of Behavior Diagrams that displays the dependencies between the actors and use cases. UML Use Case Diagram displays the system on the conceptual level.
UML Sequence Diagram is a type of Interaction Diagrams that describes the interactions between objects and classes that are involved in the scenario and the sequence of messages exchanged between them.
UML Communication Diagram in UML 2.0 (Collaboration Diagram in UML 1.x) is a type of Interaction Diagrams that displays the interactions of objects using the sequenced messages.
UML Activity Diagram is a type of Behavior Diagrams that graphically describes decomposition of the some activity on the components.
UML Component Diagram is a type of Structure Diagrams that shows how components are connected to larger components or software systems, and shows the dependencies among these components.
UML Deployment Diagram is a type of Structure Diagrams that shows the physical deployment of information generated by the software programs.
State Machine Diagrams
UML State Machine Diagram is a type of Behavior Diagrams that displays the finite state machine with states and state transitions.
UML Timing Diagram in the UML 2.0 is a specific type of Interaction Diagrams that describes the timing constraints. UML Timing Diagrams describes the behaviors of the objects during a certain period of time.
Interaction Overview Diagrams
UML Interaction Overview Diagram is a type of Interaction Diagrams that describes an overview in which the nodes represent interaction diagrams.
Composite Structure Diagrams
UML Composite Structure Diagram is a type of Structure Diagrams that shows the internal structure of a class and the interactions of elements of the internal structure of the class.

All libraries for creating UML diagrams are available inside the ConceptDraw DIAGRAM Templates and samples are located in the Rapid UML section of ConceptDraw STORE.
