A financial data warehouse is a centralized repository of financial data that can be used for reporting and analysis. Financial data warehouses are typically used by organizations to track and analyze their financial performance over time. Financial data warehouses typically contain data from multiple sources, including accounting systems, transaction systems, and other financial data sources. Data from these sources is typically integrated and cleansed before it is loaded into the financial data warehouse. Once data is in the financial data warehouse, it can be used for a variety of purposes, including financial reporting, budgeting, and forecasting. Financial data warehouses can also be used for ad-hoc analysis and decision support.
