 | Activity Diagrams - a generic flow chart used much in business modelling and sometimes in use case modelling to indicate the overall flow of the use case. This diagram type replaces the need for dataflow diagrams but is not a main diagram type for the purposes of analysis and design.
|
| State Machine Diagrams - in information systems these tend to be used to descibe the lifecycle of an important data entity. In real-time systems they tend to be used to describe state dependent behaviour.
|
| Component Diagrams - show the types of components, their interfaces and dependencies in the software architecture that is the solution to the application being developed.
|
| Deployment Diagrams - show actual computing nodes, their communication relationships and the processes or components that run on them.
