Master Data Management (MDM) is a method of managing the organization's critical data. This data, often referred to as "master data," includes information about customers, products, employees, suppliers, and other core entities that are crucial to the business operations. The goal of Master Data Management is to provide processes, governance, policies, standards, and tools that consistently define and manage the critical data of an organization to provide a single point of reference. Some key aspects of master data management includes things like data integration, data quality, and interoperability between different systems and apps.
