Data aggregation is the process of gathering data from various sources and presenting it in a summarized format. This collected information, known as aggregate data, is then used for statistical analysis, reporting, and decision-making. Imagine a retail company wanting to understand its sales performance. Instead of looking at every single transaction, it can aggregate sales data by region, product, or time period to get a clearer picture of overall trends. This process is fundamental in transforming raw, often voluminous, data into meaningful insights that can drive strategy and action.
