The following objectives were pursued with a DWH modernization of the 14-year-old, historically grown DWH:
- Cost reduction Operating costs
- Improved implementation speed for new requirements (time-to-market)
- Improvement in loading performance
- Introduction of near-real-time data management
Hyand was responsible for the technical project management, architecture and development of a DWH modernization. The challenge was to modernize a 14-year-old, historically grown DWH with many marts and ETL processes in a value-driven manner. This involved automatically connecting new sources and generating the database objects (stage/core) and ETL processes for ODI in order to achieve near-real-time management using the Oracle Golden Gate replication solution right through to the market.
Hyand significantly reduced DWH costs by replacing IBM's legacy technology (IBM Data Stage). With the implementation of the new ETL technology, the IT architecture was modernized, which was accompanied by an improvement in performance and Time2Market. The project was successfully completed with the near-real-time management of the DWH. The ETL framework implemented and provided there is a decisive factor for the adaptation of the DWH in accordance with the EU GDPR regulation.
