This UML Object Diagram Example will show you what the objects in a system are and what they can do. It also provides a static view of a system. Object diagrams, on the other hand, show how objects interact with one another over time, giving you a more detailed, dynamic view of the system. Class diagrams and UML object diagrams are very similar. While both diagrams provide a static, bird's-eye view of a system, object diagrams represent a specific instance of a class diagram to a particular point in time. They represent a class's functionality and how objects within a category interact.
