The physical data layer represents the actual data, the schemas, tables and columns, in an organization's systems.
The physical data layer consists of the following asset types:
Note
- The physical data layer asset types, Schema, Table, and Column, are available with Data Catalog. The Guided Stewardship operating model specifically includes the logical data layer and conceptual data layer asset types, such as Data Concept, Data Domain, Data Attribute, Data Entity, and Data Model.
- Although the Database asset type is a Technology Asset, it is considered part of the physical data layer.
- The Schema, Table and Column assets in Collibra Data Intelligence Platform are almost never created manually. They are mostly automatically created via the Data Catalog registration processes.
