It implies that an object diagram consists of instances of things used in a class diagram. The purpose of class diagram is to model the static view of an application. We can use an object diagram to show an example configuration of a snapshot from a class diagram. An object diagram is visually similar to a class diagram and represents the instances of a class at a given time. An object diagram describes the instance of a class. This modeling method can run with almost all Object-Oriented Methods. H�T�Mo�0���>v�! 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. The Application Hosting API describes interfaces between two software applications - Hosting System and Hosted Application , exchanging medical data while located on the same system. The example shows how a class can encapsulate all the relevant data of a particular object in a very systematic and clear way. So both diagrams are made of same basic elements but in different form.
