Sources: Observing Reality

Sources represent the systems where your organization’s data lives today: databases, warehouses, and third-party storage. Sources Zoome A Source answers one question: What exists? Sources are purely observational:
  • Schemas
  • Tables
  • Fields
  • Types
They remain as independent systems. Galaxy does not replace them. Instead, it reads from them and uses their structure as input to build a unified model.

Projects: Defining Meaning

Apple Graph A Project is a working context graph built from one or more Sources. Projects are where meaning is defined and refined. While Sources contain raw structure, Projects define how that structure maps to real-world concepts in your organization. Inside a Project, teams:
  • Define entities and concepts
  • Describe how those entities relate
  • Map semantic concepts back to real data
  • Visualize systems as a connected whole
  • Evolve understanding over time
Teams can create multiple projects so that they can model different domains independently and experiment safely. A Project should have a clear modeling scope. Some examples:
