Layers

Overview

Layers are the dataflow diagram bands that organize source, warehouse, datamart, and export objects into readable architecture stages.

Function

Layers help users understand where objects belong in the warehouse flow. Each band groups the objects for one architectural area, so tables, transformations, packages, imports, exports, and model-related work can be reviewed in context instead of as one flat diagram.

The diagram starts with a Sources band, adds configured warehouse layers in sequence, and adds an Export band when outbound flows are present. From a layer band, users can refresh the view, store or remove diagram filters, add common warehouse objects, run the DWH Wizard, synchronize the warehouse, import or export definitions, manage locks, create or update model membership, and save the diagram as a picture.

Access

Open the dataflow diagram from the DWH area, then use a layer band when you want to work with the objects that belong to a specific architecture stage. Use the DWH layer list or the Data warehouse navigation tree when you need to maintain the layer records themselves.
