In the constantly changing data landscape, changes in source systems can pose a considerable challenge, especially when it comes to efficiently transferring these changes to the DWH. Manual adjustments can be a time-consuming undertaking, especially with a large number of data sources. Our specialization lies in the development of processes that address precisely this challenge. With the metadata generator we have developed, which creates DDL and import definitions, we have implemented advanced processes that enable changes to be transferred to the production environment quickly, efficiently and with minimal risk. This ensures continuous data currency and integrity while reducing manual effort.
