It means the object diagram is closer to the actual system behavior. The purpose is to capture the static view of a system at a particular moment. We have already discussed that an object diagram is an instance of a class diagram.
It implies that an object diagram consists of instances of things used in a class diagram. So both diagrams are made of same basic elements but in different form. In class diagram elements are in abstract form to represent the blue print and in object diagram the elements are in concrete form to represent the real world object. To capture a particular system, numbers of class diagrams are limited. However, if we consider object diagrams then we can have unlimited number of instances, which are unique in nature.
Only those instances are considered, which have an impact on the system. From the above discussion, it is clear that a single object diagram cannot capture all the necessary instances or rather cannot specify all the objects of a system.
What is more, this could contain interface, packages, relationships, as well as instances including objects and links. Object diagram on the other hand is specifically designed to display a particular instance of a class diagram at a point in time. Mainly, the use of this diagram is to show examples of data structures. Unlike a class diagram, it is limited to showing the data values of objects and how they interact. Overall, it may be said that a class diagram provides a static overview of a system.
Whereas the UML object diagram models how objects interact with each other at some point. Moreover, it provides a snapshot of changes during system runtime that the class diagram does include in the display.
This post will not be complete without the examples that will help you further learn about object diagram and be able to create one yourself. They are simple and editable using an online tool GitMind. This tool is a web-based software that allows you to make different types of UML diagrams, flowcharts, or mindmaps.
Check out the examples below. Here is an example of an object diagram online that you can edit representing an order management system. It specifically shows the instance process of a purchase at a particular time in a system.
There are objects such as customer, order, normal order, and special order. In this tutorial, you will learn: twopercent. Object Diagram. An Object Diagram describes the instance of a class. It visualizes the particular functionality of a system. Objects are the real-world entities whose behavior is defined by the classes. Objects are used to represent the static view of an object-oriented system. We cannot define an object without its class.
Object and class diagrams are somewhat similar. Object Diagram Example twopercent. The objects are nothing but real-world entities that are the instances of a class. Step 1 Before drawing an object diagram, one should analyze all the objects inside the system.
Step 2 The relations of the object must be known before creating the diagram. Step 3 Association between various objects must be cleared before. Beauty Cosmetics Open Stepdiscounter 5 An object must be explored to analyze various functionalities of it.
Purpose of Object Diagram. It is used to describe the static aspect of a system. It is used to represent an instance of a class.
It can be used to perform forward and reverse engineering on systems. It is used to understand the behavior of an object. It can be used to explore the relations of an object and can be used to analyze other connecting objects. Object diagrams play an essential role while generating a blueprint of an object- oriented system. Object diagrams provide means of modeling the classes, data and other information as a set or a single unit. It is used for analyzing the online or offline system.
The functioning of a system can be visualized using object diagrams. Class Diagram Vs. Object Diagram Serial Class Object no. It represents the behavior of a system 1 It represents static aspects of a system. It never includes attributes or data It includes attributes and data values 3 values of an instance.
