Master Data Management (MDM) is often defined as 'management of master data (customer, product, supplier, etc.) that is shared across disparate IT systems and groups.' However, this simplistic description doesn't do justice to the complexity of the MDM's task and problem area. Master Data Management encompasses areas such as Customer Data Integration (CDI), Product Information Management (PIM), and Global Data Synchronization Network (GDSN); and partially overlaps the areas of Identity Management System (IdM), Business Intelligence systems, data quality, and data integration. This broad area of potential application causes multiple perspectives, diversity of stakeholders, and a fair amount of confusion across clients investigating an MDM solution.
