Usage scenario
Understanding the positioning and capabilities of SAP BW is crucial for anyone working with SAP data management solutions. Especially, SAP BW is an important component of SAP Business Data Cloud. This lesson explores the evolution of SAP BW as enterprise data warehouse solution, starting from SAP NetWeaver BW 7.5.
The figure illustrates the evolution of SAP BW.
SAP NetWeaver BW 7.5: A Data Warehouse Solution
SAP NetWeaver BW 7.5 is a powerful enterprise data warehousing solution designed to consolidate, transform, and manage data from diverse sources. This data is then used for reporting, analysis, and informed decision-making.
Here are some key components:
Data Integration: Extraction, transformation, and loading (ETL) of data from multiple sources, including SAP and non-SAP systems, enabling a unified view of the data.
Data Modeling: Robust tools for creating and managing data models, including InfoObjects, InfoCubes, and DataStore Objects, which help in organizing and structuring data for analysis.
Analytics: Design of queries that offer advanced analytical processing and reporting capabilities, such as multidimensional data filtering or exception aggregation.
However, with growing data sets and analytical requirements, managing data loading and query performance became a challenge. This led to the integration of SAP HANA with its revolutionary in-memory capabilities.
Over the years, SAP has launched different BW releases that are based on SAP HANA.
SAP NetWeaver BW 7.5 powered by SAP HANA: The In-Memory Revolution
Leveraging the in-memory capabilities of SAP HANA revolutionized SAP BW. This integration dramatically improved both data loading and query performance, leading to significantly faster processing times and the ability to handle much larger datasets. New modeling techniques and objects, such as DataStore Objects (advanced), Open ODS views, and CompositeProviders, were introduced, simplifying data flows and reducing the reliance on aggregates and indexes. This shift to in-memory processing fundamentally changed how data was handled and accessed within SAP BW.
While the integration of SAP HANA improved BW 7.5 considerably, there was still a need for simplification and streamlining. SAP BW/4HANA, built exclusively on SAP HANA.
SAP BW/4HANA: Simplification and Streamlining
SAP BW/4HANA represents a complete redesign, built exclusively on SAP HANA. This version prioritizes simplification and streamlining, reducing the complexity of data modeling and management. The number of data objects and layers was significantly reduced, making the system easier to understand and maintain. SAP BW/4HANA offers improved integration with other SAP solutions, fostering a more unified data landscape. The emphasis on real-time data processing and governance ensures that businesses have access to the most up-to-date information for informed decision-making.
SAP BW/4HANA will be the BW release for which SAP still develops enhancements in a biyearly release cycle.
