Which keyword is used to rename the resulting attribute after the application of the aggregation function?

The keyword used to rename the resulting attribute after the application of an aggregation function is AS. In SQL, for example, you can use the AS keyword in a query to provide an alias for the aggregated result.

For instance, if you want to calculate the average salary of employees and rename the resulting column to "Average_Salary", you would use:

SELECT AVG(salary) AS Average_Salary FROM employees;

In this query, "Average_Salary" is the new name for the result of the aggregation function AVG(salary). Using aliases helps to make the output of queries more understandable and readable.
