Activity Diagram

Activity becomes Action. E.g. Scan Video.

Activity compose of a sequence of

actions.

An activity diagram shows the

actions that make up an activity

now.

Action has local precondition and

local postcondition.

Action can have multiple incoming

flows.

4/13

Activity Diagram (Cont)

Action can start as a result of thoseincoming flows or receiving a signal.

New special signal, Time Signal.

New form of control flow notation is

Flow Final. Final addition is connector.

Grouping

Subactivity Diagram

An action can be decomposed into a sequence of other actions. That

means the action is implemented by a subactivity.

Input and output parameters can be added to activity diagram by placing

the input and output objects on the edge of the activity node.

Grouping (Cont)

Expansion Regions

It has an explicit input that is a collection of values.

It is executed once for each element in the input collection.

Input and output collections are in same size, value type.

Three different execution mode: parallel, iterative and stream.

Grouping (Cont)

Multi-Dimension Swimlanes

It uses activity partitions to solve multi-dimension presentation.

Because partitions can be nested, more than two dimensions can be

presented.

Exception

Two phases forexception

processing: try

and catch.

Try block =>

Protected Node.

Catch block =>

Handler body.

Class Diagram

Attributes can be presented by Compartmentalized Strings orAssociations.

Attributes are defined with the following syntax to allow thisequivalence: [visibility][/]name[:type][multiplicity][=default][{property-string}]

Visibility: (~) Package. Slash (/): Derived attribute.

Class Diagram (Cont)

An open arrow occurs at the end of an association, navigationmay occur from the source to the target.

If an X appears at the end of the association, navigation may

not occur.

If both do not occur, it allows navigation in both directions.

UML 2.0 contributes to 577.

Actions of Activity diagram help us break down each activityinto more detailed level.

Multi-Dimension partitions of Activity Diagram make us to

specify that who is taking which actions.
