The term data warehousing refers to the storage of large volumes of structured and unstructured data from various sources for analysis and reporting. Data warehousing consolidates data into a single repository, enabling businesses to perform complex queries and generate insights from historical and current data. This approach enhances decision-making as it provides a comprehensive view of business operations and trends, facilitating effective planning and strategy development. By leveraging data warehousing, organizations can improve efficiency, optimize workflows, and enhance overall data-driven decision-making processes.
