SAP S/4HANA delivers high-volume transaction processing (OLTP) and high volume real-time analytical processes (OLAP) based on a unified data model without the redundant data layers typically required by traditional RDBMS based systems. This reduces TCO while providing new opportunities to increase business value from existing investments. Examples for redundant data layers are custom-built layers based on database tuning efforts such as secondary indexes, or application built-in performance accelerators such as aggregate tables or multiple general ledger versions for different managerial reporting needs. The massive simplifications of the data model and the data processing layers enable business and technological innovations on a broad scale across all lines-of-business and industry solutions. The new application architecture simplifies system landscape architectures and accelerates cloud deployments on an economical scale.
