Data Warehousing & SAP BW

Data Warehousing Concept and Fundamentals A data warehouse is separate application environment with a dedicated

database drawing on diverse data sources and designed to support query and analysis.

A collection of integrated, subject-oriented databases designed to support the DSS function, where each unit of data is relevant to some moment in time.

A data warehouse is a copy of transaction data, specially restructured for queries and analyses – R. Kimball : The Data Warehouse Toolkit 1996.

Data Warehousing & SAP BW

Data Warehousing Concept and Fundamentals A data warehouse has the following properties:

Read only access. Cross-organizational focus Data warehouse data is stored persistently over a particular time period. Historization: Data is stored by time on a long-term basis Designed for efficient query processing Evaluation tool

Data Warehouse Objects: Standardized structuring and display of all business information Simple access to business information via a single point of entry Highly-developed reporting for analysis with self service for all areas Quick and cost-efficient implementation High performance environment. Data modeling from heterogeneous sources Relieving OLTP systems

Data Warehousing & SAP BW

OLTP vs OLAPOLTP Systems (Operative Environment)

OLAP Systems (Informative Environment)

Target Efficiency through automation of business process

Generation of knowledge (competitive advantage)

Priority High availability, higher data volume

Simple use, flexible data access

View of Data Detailed Frequently aggregated

Age of Data Current Historical

Database Operations

Add, change, delete(refresh), and read

Read

Typical Data Structure

Relational (flat tables, high normalization)

Multi-dimensional structures

Integration of data from various applications (modules)

Minimal Comprehensive

Data Set 6-18 months 2-7 years

Normalization Highly Normalized for performance

Highly denormalized for querying

User Community Nonmanagerial Managers/ Executives/Decision Maker

Data Warehousing & SAP BW

SAP BW introduction What is SAP BW

SAP BW = SAP Business Information Warehouse A state-of-the-art and end-to-end SAP data warehousing solution.

Provide knowledge workers and decision makers with rapid access to data from SAP R/3 and other non-SAP sources

SAP BW Drivers End users need current and historical data for better decision making SAP Predefined reports may not meet your needs and are hard to find. Custom SAP reports using ABAP have following limits

Static: Do not support ad-hoc querying capability Expensive to maintain Negatively impact the performance of the transaction system Difficult to integrate SAP with non-SAP data

SAP LIS (Logistics Information Systems) has following issues: All data must be in SAP R3 Requires significant amount of training, and users need knowledge of SAP data before LIS cube can be

customized The execution of queries to LIS has a negative impact on SAP R3 transaction processing performance

Third-party solutions: Can help extract data from SAP, but not end-to-end solution. Custom data warehouse solutions:

Very Expensive Implementation time is long Metadata are difficult to be synchronized with SAP R3 Extracting data from SAP R3 has traditionally been a difficult task. The integration effort is often plagued with difficulties

“… No other vendor has the same reach across all the environments in a comprehensive manner. Some vendors have software. Other vendors have hardware. But in terms of forming a complete picture across the entire corporate information factory landscape no other vendor can compete…”
