This document outlines the benefits of common data management across various financial applications such as economic capital, stress testing, and regulatory reporting. It shows how a common data mart can source data from different areas like customer, transaction, reference, and risk data to provide reconciled statutory, regulatory, and tax reporting data. This centralized approach to data management helps support applications in economic capital, stress testing, liquidity, risk appetite, and other areas by acquiring, enriching, and ensuring quality of data from finance, risk, and treasury sources.
