Layered, virtualized data architectures on BW/4HANA — built for performance today and clean extensibility for years to come.
The layered scalable architecture keeps persistence to a minimum: a lean write-optimized inbound layer, one harmonized propagation layer — and everything above it virtualized in CompositeProviders.
State of the art is combining BW artefacts with native HANA calculation views: joins, currency conversion and aggregation pushed down to the database, BW providing governance, security and lifecycle on top.
Semantic partitioning, query pruning, data tiering and load parallelization — models designed so that response times stay flat while data volumes grow year after year.
At Palkeet I rebuilt a complete legacy data flow with aDSOs and CompositeProviders during a BW/4HANA migration. At Novartis I consolidated divisional warehouses into a single group data warehouse serving worldwide financial reporting.
