A Collaboration is a collection of named objects and actors with links connecting them. They collaborate in performing some task.A Collaboration defines a set of participants and relationships that are meaningful for a given set of purposesA Collaboration between objects working together provides emergent desirable functionalities in Object-Oriented systemsEach object (responsibility) partially supports emergent functionalitiesUnlike a sequence diagram, a collaboration diagram shows the relationships among the objects. Sequence diagrams and collaboration diagrams express similar information, but show it in different ways. Because of the format of the collaboration diagram, they tend to better suited for analysis activities (see Activity: Use-Case Analysis). Specifically,...
Objects
An object is represented by an object symbol showing the name of the object and its class underlined, separated by a colon: Object_name : class_name You can use objects in collaboration diagrams in the following ways: 1. Each object in the collaboration is named and has its class specified 2. Not all classes need to appear 3. There may be more than one object of a class 4. An object’s class can be unspecified. Normally you create a collaboration diagram with objects first and specify their cl...
Actors
Normally an actor instance occurs in the collaboration diagram, as the invoker of the interaction. If you have several actor instances in the same diagram, try keeping them in the periphery of the diagram. 1. Each Actor is named and has a role 2. One actor will be the initiator of the use case
Links
Links connect objects and actors and are instances of associations and each link corresponds to an association in the class diagram Links are defined as follows: 1. A link is a relationship among objects across which messages can be sent. In collaboration diagrams, a link is shown as a solid line between two objects. 2. An object interacts with, or navigates to, other objects through its links to these objects. 3. A link can be an instance of an association, or it can be anonymous, meaning th...
Identify behavior whose realization and implementation is specifiedIdentify the structural elements (class roles, objects, subsystems) necessary to carry out the functionality of the collaborationModel structural relationships between those elements to produce a diagram showing the context of the interactionConsider the alternative scenarios that may be requiredYou can have objects and actor instances in collaboration diagrams, together with links and messages describing how they are related and how they interact. The Receive Deposit Item in the Recycling-Machine Systemdiagram shown below describes what takes place in the participating objects, in terms of how the objects communicate by sending messages t...

Learn how to use UML collaboration diagram to show the relationship between objects in a system. See the notation, examples, benefits and drawbacks of this diagram type.
A collaboration diagram, also known as a communication diagram, is an illustration of the relationships and interactions among software objects in the Unified Modeling Language ( UML ). Developers can use these diagrams to portray the dynamic behavior of a particular use case and define the role of each object.
