SOFTWARE ENGINEERING

Detailed explanation-1: -"An object diagram is a graph of instances, including objects and data values. A static object diagram is an instance of a class diagram; it shows a snapshot of the detailed state of a system at a point in time. The use of object diagrams is fairly limited, namely to show examples of data structure."

Detailed explanation-2: -A communication diagram (called collaboration in previous version of UML) without messages is also known as an object diagram, and the relationships between objects are called links. An object diagram must be a valid instantiation of a static class diagram.

Detailed explanation-3: -In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s classes, their attributes, operations (or methods), and the relationships among objects.

Detailed explanation-4: -Instance diagrams, are occasionally referred to as Object diagrams in UML. Instance diagrams are helpful in exploring the real world instances of objects and also the relationships among them. Though the class diagrams are good in depicting this information, a few see them to be more abstract.
