Data aggregation in a database system refers to the process of combining and processing data from different sources to obtain summaries, statistics, or other information about the data. Data aggregation can include various operations such as summing, averaging, minimum, maximum, and other mathematical operations that are used to process data in the database. Data aggregation is often used in database queries to obtain the results of calculations or statistics about the data in the database.
