There’s a dizzying array of approaches to master data management (MDM). You can build a solution yourself or acquire one from a vendor. The vendor’s solution may be a dedicated MDM application or a collection of functions within a larger tool. Your MDM solution can manage one data domain (customers, products, financials, etc.) or manage several. Your solution may focus on BI, operational applications, or both. And you could deploy multiple MDM solutions or just one central solution.
