Answer Details

When records are given a new value, it is called updation.
Updation refers to the process of changing the value of an existing record in a database or data structure. It involves replacing the current value with a new value.
Let's say we have a database table that stores information about students, including their names, ages, and grades. If we want to update the grade of a specific student, we would search for that student in the database and modify the grade field with a new value. This is known as updation.
Updation is an essential operation in data management as it allows us to keep the information in our records up to date. It ensures that the data accurately reflects the current state of the subject being represented.
In summary, updation is the process of changing the value of an existing record to a new value in a database or data structure.
