Layer
Overview
A Layer is an AnalyticsCreator design object that organizes schemas into an ordered logical stage of the data warehouse.
Layers help separate source-facing, integration, historization, transformation, and data mart structures without exposing internal repository storage.
Function
Use layers to structure the warehouse model and to control where schemas and their objects appear in the navigation tree.
A layer contains one or more schemas. Its sequence determines the order in which layers are presented and supports a clear progression through the warehouse architecture.
