The previously described layers are partially combined in two groups for better differentiation. Traditionally, a distinction is made between the enterprise data warehouse layer and the BI applications:

The enterprise data warehouse layer comprises the following layers: Data acquisition layer

Quality and harmonization layer

Data propagation layer

Corporate memory

It provides the single point of truth for all data and contains the data in a reusable historic view.

Single Point of Truth

A single point of truth usually means that there's no redundant dataset, but only one dataset that contains the data to be used. So there's a central data retention to be used for reporting.
