Define enterprise data models

Trigger: A new business initiative, system integration, or governance mandate requires a unified structure for organizing and understanding enterprise data.

1. Identify core business entities and data domains across the organization
2. Inventory and analyze existing data structures and source systems
3. Draft conceptual data models to map high-level entity relationships
4. Develop detailed logical data models specifying attributes, keys, and naming conventions
5. Validate the proposed models against business requirements and governance standards
6. Publish the approved data models to a centralized enterprise architecture repository

Outcome: An approved, standardized set of enterprise data models is published and integrated into the organization's architecture repositories.
