Master data management (MDM) is a category of software infrastructure that operationalizes the acquisition, distribution, and management of core data entities, including customers, products, and suppliers. As enterprises grapple with service-oriented architecture (SOA) demands, they increasingly recognize the need to manage master data, such as customer, product, supplier, location, and employee data, outside of the core applications that use it. Doing so offers the promise of enabling existing applications to work off the same master data, reducing data quality and redundancy concerns and improving the support of instance consolidation, supplier collaboration, Lean Manufacturing, eCommerce, and business intelligence initiatives.
