+# Master Data Management
+
+## Definition
+
+**Master Data Management (MDM)** is the discipline of creating and maintaining consistent, authoritative representations of important business entities across systems.
+
+Common master-data domains include Customer, Product, Employee, Supplier, Location, and Content.
+
+## Simple Mental Model
+
+> **MDM answers: "What is the trusted identity of this thing across the company?"**
+
+## How It Works
+
+Example:
+
+```text
+CMS: Show ID = 784
+JW Player: Media ID = ABC91
+Advertising: Content ID = 55129
+Analytics: Content Key = 9031
+```
+
+These may all refer to the same program.
+
+MDM establishes mappings and an authoritative representation.
+
+## Example
+
+```text
+CMS
+"The Great Show - S1E1"
+
+Video Platform
+"great_show_ep01"
+
+Programming
+Program ID 81817
+
+Advertising
+Asset 500992
+```
+
+A governed master-content entity can map all of them to one canonical identity.
+
+## How It Fits Into the Bigger Picture
+
+MDM is related to [[Dimension Table]] and [[Data Governance]], but it is broader than analytics.
+
+Master Data can serve operational and analytical systems.
+
+## My Company / Real-World Context
+
+Content is a likely MDM challenge in a media organization because the same content may have identifiers in CMS, video, OTT, linear scheduling, advertising, and analytics systems.
+
+## CTO Perspective
+
+MDM initiatives can become enormous and expensive.
+
+Start with:
+
+> **Which business entity is causing enough inconsistency that centralized management would create meaningful value?**
+
+Do not start with purchasing an MDM platform.
+
+### Questions to Ask
+
+- Which entities exist in multiple systems?
+- Which system is authoritative for each attribute?
+- How are duplicates resolved?
+- How are identifiers mapped?
+- Who is the [[Data Owner]]?
+- Do we need full MDM tooling or a simpler governed approach?
+
+## Meeting Scenario
+
+**Situation:** Your team spends significant time manually mapping content IDs across systems.
+
+**Possible response:**
+
+> "We clearly have a master-data problem around content identity. Let's define which system owns each attribute and the canonical identity we need before deciding what technology is required."
+
+## Key Takeaways
+
+- MDM manages authoritative identities across systems.
+- It addresses inconsistency and duplication.
+- Master Data is broader than analytical [[Dimension Table|Dimension Tables]].
+- [[Data Governance]] determines ownership and authority.
+- Solve the entity problem before choosing the platform.
