Activity Partition
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 here:

OMG UML Specification:
The OMG Unified Modeling Language specification, (v2.5.1, p.408) states:
An ActivityPartition is notated with two, usually parallel lines, either horizontal or vertical, and a name labeling the partition in a box at one end. Any ActivityNodes and ActivityEdges placed between these lines are considered to be contained within the partition. This notation for an ActivityPartition is colloquially known as a swimlane, (...).
