Represent the entities 'Student' and 'Course' and their relationship using a class diagram
Answers
Class diagrams are the main building block in object-oriented modeling. They are used to show the different objects in a system, their attributes, their operations and the relationships among them.
The following figure is an example of a simple class:
Simple Class diagram
Simple class diagram with attributes and operations
In the example, a class called “loan account” is depicted. Classes in class diagrams are represented by boxes that are partitioned into three:
The top partition contains the name of the class.
The middle part contains the class’s attributes.
The bottom partition shows the possible operations that are associated with the class.
The example shows how a class can encapsulate all the relevant data of a particular object in a very systematic and clear way. A class diagram is a collection of classes similar to the one above.
