Definition
Master Data are core data describing the most important entities within an organisation and shared across multiple systems and processes.
Human Explanation
They include essential data about customers, products, suppliers or employees that should remain unambiguous and consistent throughout the organisation.
Why it Matters
Consistent Master Data reduce errors and allow different systems to work together correctly.
Conceptual Boundary
Master Data do not include transactional or temporary data. They describe relatively stable entities relevant to the organisation's operations.
Practical Perspective
Maintaining one trusted version of Master Data is one of the most important objectives of Data Governance.
