Description |
Learning Priority |
|
Activity Diagram |
Depicts high-level business processes, including data flow, or to model the logic of complex logic within a system. See UML Activity diagram guidelines. |
High |
|
Class Diagram |
Shows a collection of static model elements such as classes and types, their contents, and their relationships. See UML Class diagram guidelines. |
High |
|
Communication Diagram |
Shows instances of classes, their interrelationships, and the message flow between them. Communication diagrams typically focus on the structural organization of objects that send and receive messages. Formerly called a Collaboration Diagram. See UML Collaboration diagram guidelines. |
Low |
|
Component Diagram |
Depicts the components that compose an application, system, or enterprise. The components, their interrelationships, interactions, and their public interfaces are depicted. See UML Component diagram guidelines. |
Medium |
|
Composite Structure Diagram |
Depicts the internal structure of a classifier (such as a class, component, or use case), including the interaction points of the classifier to other parts of the system. |
Low |
|
Deployment Diagram |
Shows the execution architecture of systems. This includes nodes, either hardware or software execution environments, as well as the middleware connecting them. See UML Deployment diagram guidelines. |
Medium |
|
Interaction Overview Diagram |
A variant of an activity diagram which overviews the control flow within a system or business process. Each node/activity within the diagram can represent another interaction diagram. |
Low |
|
Object Diagram |
Depicts objects and their relationships at a point in time, typically a special case of either a class diagram or a communication diagram. |
Low |
|
Package Diagram |
Shows how model elements are organized into packages as well as the dependencies between packages. See Package diagram guidelines. |
Low |
|
Sequence Diagram |
Models the sequential logic, in effect the time ordering of messages between classifiers. See UML Sequence diagram guidelines. |
High |
|
State Machine Diagram |
Describes the states an object or interaction may be in, as well as the transitions between states. Formerly referred to as a state diagram, state chart diagram, or a state-transition diagram. See UML State chart diagram guidelines. |
Medium |
|
Timing Diagram |
Depicts the change in state or condition of a classifier instance or role over time. Typically used to show the change in state of an object over time in response to external events. |
Low |
|
Use Case Diagram |
Shows use cases, actors, and their interrelationships. See UML Use case diagram guidelines. |
