Modeling in SAP BI
Purpose
The tool you
use for modeling is the Data Warehousing Workbench. Depending on your analysis
and reporting requirements, different BI objects are available to you for
integrating, transforming, consolidating, cleaning up, and storing data. BI
objects allow efficient extraction of data for analysis and interpretation
purposes.
Process Flow
The
following figure outlines how BI objects are integrated into the
dataflow:
Data that
logically belongs together is stored in the source system as DataSources.
DataSources are used for extracting data from a source system and transferring
it into the BI system.
The Persistent Staging
Area (PSA) in the BI system is the inbound storage area for data from the
source systems. The requested data is saved, unchanged from the source
system.
The transformation
specifies how the data (key figures, time characteristics, characteristics) is
updated and transformed from the source, into an InfoProvider or
InfoSource. The transformation rules map the fields of the source to at least
one InfoObject in the target. The information is mapped in structured form
using the InfoObjects.
You need to
use an InfoSource if you
want to execute two transformations one after the other.
Subsequently,
the data can be updated to further InfoProviders. The
InfoProvider provides the data that is evaluated in queries. You can also
distribute data to other systems using the open hub
destination.
