Object Diagram Vs Class Diagram

Example class diagram vs object diagram an object diagram is a snapshot of the objects in a system at a point in time. A static object diagram is an instance of a class diagram.

Perhaps a better name would be static structural diagram but class diagram is shorter and well established.

Object diagram vs class diagram. The figure shows the class diagram of party composition structure and a particular snapshot at a point in time. An object diagram is a graph of instances including objects and data values. Object diagrams show specific instances of those classifiers and the links between those instances at a point in time.

It visualizes the particular functionality of a system. In contrast an object diagram will show how objects in your system are interacting with each other at some point in time and what values those objects contain when the program is in this state. An object diagram describes the instance of a class.

The difference between the class and object diagram is that the class diagram mainly represents the birds eye view of a system which is also referred to as an abstract view. Object diagrams use notation that is similar to that used in class diagrams. It also stated that object diagram is a class diagram with objects and no classes.

We can use an object diagram to show an example configuration of a snapshot from a class diagram. The difference between class diagram and object diagram is that class diagram represents the classes and their relationships between them while object diagram represents the objects and their relationships between them at a particular moment. Being the most important uml diagram the class diagram consists of class attributes and relationships which are its essential elements.

Class diagrams show the actual classifiers and their relationships in a system. Object and class diagrams are somewhat similar. The relationship between the different objects is described by the class diagram which ensures the design and analysis of an application and views it in its static form.

It shows a snapshot of the detailed state of a system at a point in time. A class diagram will show what the objects in your system consist of members and what they are capable of doing methods mostly static. Object diagram was defined in now obsolete uml 142 specification as a graph of instances including objects and data values.
