A data warehouse is a large, central repository of data that has been processed, organized, and made available for analysis and decision-making purposes. It is specifically designed to support business intelligence tools and applications, and typically includes data from multiple sources that have been cleaned, transformed, and integrated into a unified and coherent format. Data marts and transaction processing marts are subsets of data warehouses that focus on specific functional or departmental areas, while a data repository is a more general term that describes any central store of data, whether or not it has been processed or organized for analytical purposes.
