Naming convention can be defined as standard set of rules which tell us how an identifier will be used.

Whenever a question arises “how to name an element” the answer is naming convention.

Why it is required?

• gradeofstudent
• GradeOfStudent

In above case, first case is difficult to read than second case where we read and understand easily what it is about.

So, naming convention is required to reduce the effort needed to read and understand the source code. It also maintains the consistency of data.
