UML Collaboration Diagrams

UML Collaboration Diagrams

Use a collaboration diagram (collaboration diagram: An interaction diagram that shows, for one system event described by one use case, how a group of objects collaborate with one another.) to show relationships among object roles such as the set of messages exchanged among the objects to achieve an operation or result.

UML Collaboration diagrams (interaction diagrams) illustrate the relationship and interaction between software objects. They require use cases, system operation contracts, and domain model to already exist. The collaboration diagram illustrates messages being sent between classes and objects (instances). A diagram is created for each system operation that relates to the current development cycle (iteration).

When creating collaboration diagrams, patterns are used to justify relationships. Patterns are best principles for assigning responsibilities to objects and are described further in the section on patterns. There are two main types of patterns used for assigning responsibilities which are evaluative patterns and driving patterns.

Each system operation initiates a collaboration diagram. Therefore, there is a collaboration diagram for every system operation. Edraw is ideal for software designers and software developers who need to draw UML activity diagrams
