Master Data Management
Master Data Management, abbreviated MDM, is the discipline of creating and maintaining a single authoritative record (the "golden record" or "master") for each business entity — customer, product, employee, supplier, asset — by reconciling and deduplicating data from multiple source systems. MDM was a mature enterprise discipline two decades before generative AI, with vendors like Informatica MDM, IBM InfoSphere, SAP MDG, Reltio, Stibo Systems, and Profisee owning the space. The MDM process: pull entity records from source systems, normalize fields (addresses, phone numbers, names), run probabilistic matching (Splink, Zingg, or commercial MDM engines), survivorship rules to choose the best value for each field, and publish the golden record back to consumers with provenance preserved. In an AI context, MDM matters because LLMs grounded in RAG are only as accurate as the entity resolution underneath — if "Acme Corp", "Acme Corporation", and "ACME, Inc." all appear as distinct records, the LLM will give inconsistent answers about Acme. Practical recipe: pick a single MDM domain to start (typically customer or supplier), define matching rules (exact email + fuzzy name + address proximity = match), configure survivorship (most recent, highest-trust source, longest non-null), run the matching engine, review the gray-zone matches with human stewards, and publish the golden records to a clean dimension that both BI and AI consume. AI governance teams insist MDM run upstream of any AI ingestion because resolving entities at retrieval time is far harder than resolving them at the source.
MDM is Oxcyon's 25-year native tongue: Centralpoint's golden-record discipline — deduplication, fuzzy matching, survivorship, audit trails — predates the modern MDM vendor landscape because Oxcyon was solving these problems for enterprise CMS clients 25 years ago. The AI layer now consumes those golden records natively. MDM runs on-premise, tokens meter per skill, and MDM-grounded chatbots deploy through one line of JavaScript.
