What is data aggregation?

Data aggregation is the process of collecting and combining data from multiple sources into a single database or repository.

How is data aggregation done?

Data aggregation is typically done in the following order, from start to finish:

1. Raw data is collected from various sources and may contain structured and unstructured data.
2. The collected data is cleaned, standardized, and integrated.
3. The transformed data is combined into a single dataset.
4. The data is now in a structured format and is ready for further analysis.
