Data Models provide a birds-eye view of how subject areas (aka metadata entities) relate. For example, a series contains seasons, seasons have episodes and episodes have events.
Goal: Developed by a business audience, this non-technical view identifies relationships among series, season, episodes, events, etc. from a Viewer's point of view.
How: 1) Focuses on the important subject areas that reach across the organization; 2) does not include field names; & 3) keeps the viewer in mind - not internal databases or tool.
Benefits: 1) Helps onboard new employees to understand the organization's important subject areas; and, 2) seeds a data model for future projects.
