What is Data Aggregation?
Data aggregation is the process of summarizing or grouping the records in a dataset. If you have, say, a list of 10,000 students in a university, data aggregation entails that you group them according to specific categories. Depending on what’s required, you may aggregate the list of students according to their programs and courses, for instance. You may also group them according to year level, gender, or age.
Beyond the university example, data aggregation is useful across all industries, including finance and banking, technology, production, marketing, and advertising.
