When aggregating data, all data may be used in the aggregation, but if you want only specific grouping, use the Group By specification.
What is Data Aggregation?
A large amount of data is summarized through the process of data aggregation in order to conduct in-depth analysis. At its most fundamental level, it is gathering data from a variety of specified databases and arranging it into a more simpler style, typically using total, average, mean, or median references. But it's vital to remember that not all aggregated data must be numerical; non-numeric data components, for instance, can also be counted.
Enterprises must gather data in order to understand consumer behavior, increase operational efficiency, and ultimately, understand the performance of the business or its products.
