UML Sequence Diagram Loop
A UML Sequence Diagram Loop visually represents a system to help you understand, modify, maintain, or document it.

Uses of UML Sequence Diagram Loops
Initially, Unified Modeling Language (UML) diagrams were used as a general-purpose modeling language in the field of software engineering. In time, its usage has extended to:
- Improving integration between structural models (e.g. class diagrams) and behavioral models (e.g. activity diagrams).
- Defining a hierarchy and breaking down a software system into components and sub-components.
The UML Sequence Diagram Loop visualizes the interactions and the order in which they must occur to trigger a specific event.

How to create your own UML Sequence Diagram Loop
UML sequence diagrams are quite simple to create. In Cacoo, you can start with a template or build it on a blank sheet.
1
Break down your project into steps.
2
Using shapes, define each of the steps and actors involved in the process.
3
Use arrows to define interactions and conditionality.
4
Use the arrows to define the connections.
5
Model the process flow by adding text on the lines and arrows between the shapes.
