Structured Activity
Structured Activity elements are used in Activity diagrams. A Structured Activity is an activity node that can have subordinate nodes as an independent Activity Group. You can set an option to ensure that no other Activities or their side effects interfere with this Activity's processing (the Must Isolate checkbox in the Structured Activity element Properties dialog).
Enterprise Architect provides a number of forms of Structured Activity, both basic and specialized.

Create Structured Activities
When you drag a Structured Activity icon from the Toolbox onto a diagram, a short menu displays from which you select one of the following options:
| · | Loop Node |
| · | Conditional Node |
| · | Other |
The first two options specifically create a Loop Node or Conditional Node.
The Other option displays the New Structured Activity dialog, on which you can select to create one of five types of Structured Activity element.

|
Conditional Node |
Represents an arrangement of Actions and Activities where choice determines which Activities are performed.
|
|
Structured Activity Node |
Represents an ordered arrangement of executable Activity nodes (Actions, Decisions, Merges and so on) that can include branched and nested nodes; this is the base element from which the other types of Structured Activity are derived.

|
Sequential Node |
Represents a sequential arrangement of executable Activity nodes.

| · | To protect the processing of a Loop or Conditional Node Structured Activity from interference from other Activities or their side effects, open the element's Properties dialog and select the Must Isolate checkbox on the Loop or Condition tab |
