Subject: SAP-BW/4HANA
SAP BW/4HANA is SAP’s next-generation data warehouse solution optimized for the SAP HANA platform. It is designed to support advanced analytics and real-time data processing by leveraging HANA’s in-memory computing power. A core aspect of SAP BW/4HANA’s architecture is its modern and simplified data modeling capabilities, which enable organizations to build flexible, scalable, and high-performance data warehouse solutions.
This article provides an overview of key concepts, components, and best practices involved in SAP BW/4HANA data modeling.
ADSOs are the central data storage objects in BW/4HANA, replacing classic DataStore Objects (DSOs). They provide multiple modeling modes to store and process data, such as:
CompositeProviders combine data from multiple ADSOs and other providers virtually, enabling flexible multi-source reporting without data duplication. They support complex join, union, and projection operations.
Open ODS Views allow modeling on top of external data sources without physically replicating the data. This supports a virtual data layer that is especially useful for operational reporting and real-time analytics.
InfoObjects are reusable semantic building blocks representing business entities like customers, products, or time. In BW/4HANA, InfoObjects are enhanced to work seamlessly with HANA-optimized models.
SAP BW/4HANA data modeling is primarily done using the SAP BW Modeling Tools in Eclipse, which offers a rich and integrated development environment with capabilities like:
SAP BW/4HANA data modeling represents a significant evolution from classic BW, emphasizing simplicity, performance, and flexibility. By mastering its core objects like ADSOs, CompositeProviders, and Open ODS Views, organizations can build agile data warehouse solutions capable of meeting modern analytics demands.
