What is master data management?
Master data management (MDM) is the practice of keeping one trusted record for each customer, product, supplier and location across all the systems a business uses.
What counts as master data
Master data describes the core things a business deals with again and again:
- Parties: customers, patients, passengers, companies and contacts.
- Products and services you sell or buy.
- Suppliers and vendors.
- Locations and assets: sites, aircraft and equipment.
Transactions such as orders, invoices, flights and visits are not master data, but every one of them points to it. When master data is wrong, every report built on those transactions is wrong too.
How MDM works
- Connect the systems that hold master data.
- Standardize formats and check quality.
- Match records that describe the same thing.
- Merge them into golden records using survivorship rules.
- Govern: data stewards review conflicts, and access, masking and audit rules apply.
- Distribute the golden records to reports, apps and AI agents.
Common MDM styles
| Style | How it works | Good for |
|---|---|---|
| Registry | An index links matching records; the sources stay unchanged | A quick, read-only start |
| Consolidation | Records are copied into a hub that builds golden records | Reporting, analytics and AI |
| Coexistence | Golden records are also synced back to the source systems | Clean data inside every app |
| Centralized | Records are created and edited only in the hub | Large enterprises with strict control |
GoldMerge uses the consolidation style. Your systems stay as they are, and golden records feed your warehouse, apps and AI agents.
What MDM costs
Enterprise MDM platforms are usually sold through custom annual contracts, often in the six figures, plus an implementation project. GoldMerge costs $100 per source per month with the warehouse included. Compare the costs.
Signs you need MDM
- The same customer is counted twice, or three times.
- Teams argue about whose numbers are right.
- Someone merges spreadsheets by hand every month.
- Customers get duplicate emails or invoices.
- A privacy request takes days to answer.
Questions
What is the difference between MDM and a data warehouse?
A warehouse stores data for analysis. MDM decides which records describe the same customer, product or supplier and builds one trusted version of each. GoldMerge does both.
What is the difference between MDM and a CRM?
A CRM is one system where sales and service teams work. MDM sits across all your systems, including the CRM, and keeps one trusted record for each customer.
Is MDM only for large companies?
No. Any company whose customer data lives in several apps has the same duplicate and conflict problems. GoldMerge brings MDM to teams of 10 to 500 people.
How long does MDM take to set up?
Enterprise programs often take months. With GoldMerge you pick your sources and fill in one connection card for each.
