Virtual Data Models (VDMs)

VDMs allow you to access data in one component and use it in another without having to persist the data a second time.

Demand Data Foundation (DDF) with Unified Demand Forecast (UDF) can use VDM connections to an SAP Customer Activity Repository system where historical demand data is available. The VDMs allow UDF to consume SAP HANA views with aggregated time series data in SAP Customer Activity Repository and use the data as input for demand modeling and forecasting.

Note that the consumed time series are not persisted in the DDF data model.

Features

UDF can use the following VDMs to consume SAP HANA views in SAP Customer Activity Repository:

Implementation Considerations

The data that UDF consumes via the VDMs is stored in the SAP HANA content of SAP Customer Activity Repository. You can view and manage SAP HANA content using SAP HANA studio.
