Enterprise Architect supports two types of Activity Partition:
- The Activity Partition feature, described in this topic, which is used to logically organize an Activity element
- The Activity Partition element, which is used to logically organize an Activity diagram.
In effect, these are the same. They partition the Actions of the Activity without affecting the token flow, helping to structure the view or parts of the Activity.
An example of a feature-partitioned Activity is shown below:
To define Partitions using the feature:
- Right-click on the Activity element. The context menu displays.
- Select the Advanced | Partition Activity menu option. The Activity Partitions dialog displays.
- In the Name field, type the name of a partition. Click on the Save button.
- Repeat step 3 for each partition to be created.
OMG UML Specification
The OMG UML specification (UML Superstructure Specification, v2.1.1, p. 341) states:
Partitions divide the nodes and edges to constrain and show a view of the contained nodes. Partitions can share contents. They often correspond to organizational units in a business model. They may be used to allocate characteristics or resources among the nodes of an activity.
The OMG UML specification (UML Superstructure Specification, v2.1.1, p. 341) also states:
An activity partition is a kind of activity group for identifying actions that have some characteristic in common.
