Data aggregation is the process of collecting and summarizing information from various sources to provide a comprehensive view of a particular dataset. This technique is commonly used in fields like business, healthcare, and research to analyze trends, patterns, and insights. By combining data from multiple sources, organizations can make informed decisions based on a broader understanding of the information. In data aggregation, raw data is often transformed into a more digestible format, such as averages, totals, or percentages. This helps to simplify complex datasets, making it easier for stakeholders to interpret the results. Tools and software for data analysis often facilitate this process, enabling users to visualize and explore the aggregated data effectively.
