Object Diagram

modelling

Is a UML diagram [see page 15, derived] from the class diagram that shows a snapshot of a system at a given state. It has a series of objects each linked to other objects, with links demonstrating the established associations in the parent class diagram.

Objects are instances of a class and identified by an underlined class name (of the form variableName: className). You can add an association tagged with <<instanceOf>> from an object to its class when placing them in a class diagram. In an object diagram associations simply reflect class associations with multiplicities having to match.
