SAP Business Intelligence (BI) ans SAP Business Warehouse (BW) : Overview and Architecture

 SAP BW and BI Introduction

SAP Business Intelligence (BI) means analyzing and reporting of data from different heterogeneous data sources. SAP Business Warehouse (BW) integrates data from different sources, transforms and consolidates the data, does data cleansing, and storing of data as well. It also includes data modeling, administration, and staging areas.

The data in SAP BW is managed with the help of a centralized tool known as SAP BI Administration Workbench. The BI platform provides infrastructure and functions which include −

• 1. OLAP Processor
• 2. Metadata Repository
• 3. Process designer and other functions

The Business Explorer (BEx) is a reporting and analysis tool that supports query, analysis, and reporting functions in BI. Using BEx, you can analyze historical and current data to a different degree of analysis.

SAP BW is known as an open, standard tool that allows you to extract the data from different systems and then send it to the BI system. It also evaluates the data with different reporting tools and you can distribute this to other systems.

The architecture of Business Intelligence

BI has three-tier architecture:

Database Server: Where data is physically stored.( ODS, PSA, Infocube and metadata repository).

Application Server: The application server is based on the OLAP processor. It is used to retrieve data stored in the database server.

Presentation Server: Manages reporting and data access.

1. Data is extracted from Source Systems.
2. Data is staged at the Persistent Storage Area(PSA). This holds Source like data.
3. Data is cleansed, loaded, and stored in Data Store Object.
4. Data is viewed at multiple dimensions in the Infocube.
5. Data is available by the OLAP processor to the Business Explorer to display data as per the Analysis requirements of the Business.
6. Data can be made available to SAP/Non-SAP, Data Marts by the Open Hub Service. ( InfoSpoke).
