What is Master Data Management (MDM)?
Master Data Management is the discipline and tooling used to maintain a single, consistent, and accurate set of core business records across systems.
Definition
Master Data Management (MDM) is the practice of defining and governing an organisation's critical shared data, such as customers, suppliers, products, and chart-of-accounts entries, so that it is consistent everywhere it is used. It combines policies, ownership, and software that consolidate records, resolve duplicates, and distribute an authoritative version to connected systems. The goal is to eliminate conflicting versions of the same entity that arise when different applications maintain their own copies. MDM is closely tied to data governance and is foundational to reliable reporting and automation.
How Master Data Management Works in ERP
Because an ERP holds much of a company's master data, it is often a central participant in MDM, either as the system of record or as a consumer of a dedicated MDM hub. MDM processes ensure, for example, that a customer created in the CRM matches the customer record in the ERP rather than creating a duplicate. Standardised, de-duplicated master data improves invoicing accuracy, procurement, and analytics. Larger enterprises may run a separate MDM platform that synchronises master data across the ERP and other applications.

Frequently Asked Questions
What counts as master data?
Master data is the relatively stable core reference data shared across processes, such as customers, suppliers, products, employees, and accounts, as opposed to transactional data like individual orders and invoices.
Can an ERP serve as the MDM system?
Yes; many mid-sized organisations use their ERP as the authoritative master-data hub, while larger enterprises with many systems often deploy a dedicated MDM platform that governs data across the ERP and other applications.
