Which aggregate function returns the total number of records?

Explanation:
Aggregate operations summarize a set of values into a single result. To get the total number of records, you use a counting operation. Count tallies the number of rows, producing the total record count. This is different from Sum, which adds up the values in a numeric field; Max, which returns the highest value; and Min, which returns the lowest value. In most systems, COUNT(*) counts every row, reflecting the total number of records in the dataset.
