SAP�s BW Information Model: Overview
SAP�s BW information model is based on the core building
block of InfoObjects which are used to describe business processes and
information requirements. They provide basis for setting up complex information
models in multiple languages, currencies, units of measure, hierarchy, etc. The
key elements in the SAP�s BW information model are:
- DataSources
- InfoSources
- ODS Objects
- InfoCubes
- InfoProviders
- MultiProviders
Data Sources
DataSources are flat data structures containing data that
logically belongs together. They are responsible for extracting and staging data
from various source systems.
InfoSources
InfoSources are the group of InfoObjects that belong together
from a business point of view. It contains the transactional data obtained from
the transactions in online transactional processes (OLTP) and master data such
as addresses of customers and organizations, which remain unchanged for longer
time period.
ODS objects
An ODS object is a dataset which is formed as a result of
merging data from one or more info sources. In it information is stored in the
form of flat, transparent database tables that are used for preparing reports
and quality assurance purposes.
InfoCubes
InfoCubes are multidimensional data storage containers for
reporting and analysis of data. They consist of keys figures and characteristics
of which latter is organized as dimensions facilitating users to analyze data
from various business perspectives such as geographical area or types of sales
channel.
InfoProviders
InfoProviders refer to all the data objects that are present
in the SAP BW systems. These include all the data targets viz. InfoCubes, ODS
objects and master data tables along with Info sets, remote Infocubes and
MultiProviders.
MultiProviders
MultiProvider is a virtual information provider which is a
combination of any two physical or virtual info providers. MultiProviders do not
contain any data and are used to combine data from different info providers.
Their main purpose is to make this data accessible for reports and analysis.
