The term "data aggregation" in analytics refers to the process of collecting, combining, and summarizing large sets of data from various sources to provide meaningful insights. This technique allows organizations to analyze trends, patterns, and correlations within the data, leading to informed decision-making. Aggregated data can come from different sources, such as databases, APIs, and third-party services, and may involve calculations like sums, averages, and counts. By synthesizing data in this way, businesses can garner a comprehensive understanding of their operations and market conditions.
