The document discusses collaboration diagrams, which capture the dynamic behavior of objects collaborating to perform tasks. Collaboration diagrams illustrate object interactions through messages in a graph format. They show objects, links between objects, and messages to model control flow and coordination. Notations are used to represent classes, instances, links, messages, return values, self-messages, conditional messages, iteration, and collections of objects. Examples of converting sequence diagrams to collaboration diagrams for making a phone call, changing flight itineraries, and making a hotel reservation are provided.

- 1. Duration: 3hrs 1 Ramakant Soni Assistant Professor Dept. of Computer Science B K Birla Institute of Engineering & Technology, Pilani, India Ramakant Soni @ BKBIET Pilani
- 2. Collaboration Diagram Definition Collaboration Diagrams captures dynamic behavior of the objects in the system (message-oriented). They are very useful for visualizing the relationship between objects collaborating to perform a particular task. Ramakant Soni @ BKBIET Pilani 2 Their purpose is to: Model flow of control Illustrate coordination of object structure and control
- 3. Collaboration Diagram Elements There are three primary elements of a collaboration diagram: 1. Objects 2. Links 3. Messages Ramakant Soni @ BKBIET Pilani 3 3. Messages
- 4. What it represents? Collaboration Diagrams illustrate object interactions in a graph or network format. Ramakant Soni @ BKBIET Pilani 4
- 5. Notations used for Collaboration Diagrams To show an instance of a class, the regular class box graphic symbol is used, but the name is underlined. Additionally a class name should be preceded by a colon. Ramakant Soni @ BKBIET Pilani 5 An instance name can be used to uniquely identify the instance.
- 6. Links, Messages and Return Value Ramakant Soni @ BKBIET Pilani 6
- 7. “Self” Messages A message can be sent from an object to itself. This is illustrated by a link to itself, with messages flowing along the link. Ramakant Soni @ BKBIET Pilani 7
- 8. Conditional Messages A conditional message is shown by following a sequence number with a conditional clause in square brackets, similar to the iteration clause. The message is sent only if the clause evaluates to true. Ramakant Soni @ BKBIET Pilani 8
- 9. Iteration or Looping Iteration is indicated by following the sequence number with a star( * ). This expresses that the message is being sent repeatedly, in a loop, to the Ramakant Soni @ BKBIET Pilani 9 sent repeatedly, in a loop, to the receiver. It is also possible to include an iteration clause indicating the recurrence values.
- 10. Representing Collections (Multiobject) A multiobject is a set of instances. Ramakant Soni @ BKBIET Pilani 10
