Master Data refers to the consistent, accurate, and authoritative information about key entities that are essential for an organization’s operations, analytics, and decision-making. These entities—such as people, organizations, locations, assets, systems, customers, suppliers, and products—provide the context and reference for transactions and activities across various domains. Relatively stable over time, Master Data ensures uniformity and serves as a single source of truth, supporting data integration, efficient processes, regulatory compliance, and reliable reporting while enabling better decision-making and operational excellence.
