Logical data layer

The logical data layer defines data structures within an organization's system in the Guided Stewardship operating model.

The logical data layer consists of the following asset types:

• Data Model
• Data Entity
• Data Attribute

Note Although the System asset type is a Technology Asset, it adds higher-level structure to the logical data layer and is considered part of the logical data layer.

The logical data layer can be visualized as a tree-like structure, starting with a high-level System and Data Model assets, and branching out with implementation-specific Data Entity and Data Attribute assets.

Tip The Data Entity-Data Attribute structure is closely related to the Data Domain-Data Concept structure of the conceptual data layer. The main difference between them is that the logical data layer describes the structure in an individual System, whereas the conceptual data layer is context-independent.
