What are Data Model Objects (DMOs) and the Unified Data Model in Data Cloud?
Suggested answer
The Unified Data Model (UDM) is Data Cloud's standardized data schema. Data Model Objects (DMOs) are the individual tables within the UDM:
1. Standard DMOs — pre-built objects aligned to common data concepts: Individual (person), Contact Point (email, phone, address), Sales Order, Engagement (web/email events), and more.
2. Custom DMOs — user-defined objects for data that doesn't fit standard schemas.
3. Key distinction: Person Account vs Individual — in B2B orgs with Person Accounts, individuals are modeled using both Account and Contact fields; the Individual DMO is the canonical person record in Data Cloud.
4. Engagement Concept Objects — capture behavioral events (email opens, web clicks, purchases). DMO relationships (lookups) allow joining data across objects for segmentation and insights.
