Aggregation Functions are used to perform calculations on a set of values to return a single summarized result. These functions are often applied to columns in a database to derive useful insights from the data.

For better understanding:

1. Aggregation Functions in the Data World:

In the realm of data management and analysis, aggregation functions play a crucial role. These functions are specialized tools used to process and summarize data, particularly when dealing with large datasets. Instead of looking at individual data points, aggregation functions allow us to analyze groups of data and distill meaningful information.

2. Performing Calculations on a Set of Values:

Aggregation functions operate on sets of values, which are typically found in columns of a database. Instead of working with individual records, these functions work with groups or entire columns of data. This allows for the calculation of summary statistics, totals, averages, and other aggregated measures.
