Master Data Management (MDM)
Master Data Management (MDM) refers to the organisational, process and technical measures with which companies keep their master data – on customers, suppliers, materials or accounts – consistent and quality-assured across systems.
Master data is the foundation of practically every ERP process. Duplicate customers, inconsistent part numbers or outdated supplier information lead directly to errors in orders, invoices, reporting and compliance checks. A single source of truth is therefore the central goal of MDM.
What MDM covers
Methodically, MDM addresses data modelling, duplicate detection, validation rules, approval workflows, data enrichment and audit trails. The result is a „golden record“ – one authoritative version of each master-data object that all systems reference.
Example: MDM in a corporate group
An international group holds customer data in six different systems – ERP, CRM, marketing automation, service ticketing, an e-commerce shop and an analytics platform. Without MDM, inconsistencies appear quickly: the same customer is „Main St. 1“ in one system and „Mainstreet 1“ in another. The MDM platform defines the ERP as the source of truth for customer master data, and every change there is replicated automatically to the other systems – producing a consistent data base, correct reports and fewer surprises on customer calls.
MDM and the data pipeline
MDM is closely related to the data warehouse and ETL processes: clean master data upstream is what makes downstream analytics trustworthy.
