Layer

Overview

A Layer is a repository entity used to organize schemas and warehouse objects by architectural level. Layers define the visible structure under the data warehouse navigation tree and help separate source, staging, transformation, core, and reporting areas.

Function

Use the Layer entity to control the ordered list of warehouse layers. Each layer has a name, description, and sequence number. The sequence number controls the order in which layers appear, and it must be unique.

The layer page is an editable list. Changes are saved from the list page, and saving recreates the diagram structure so the updated layer order and layer metadata are reflected in the interface.

Access

Layers can be opened from the repository navigation tree or from the DWH ribbon tab. Individual layer entries appear below the Layers node in sequence-number order.
