how we create added value with your data.

Data architecture & engineering

In the constantly evolving data landscape, our experts in data architecture and engineering offer robust systems. Our services range from classic DWH Development to Data Warehouse Automation and Big Data scenarios. We rely heavily on tool manufacturers for DWH and ETL & DWA and on Data Modeling to ensure that data is mapped accurately and consistently. By Data Mesh we not only mean architectural principles, but also offer guidance on how to translate them into practical concepts and systems. Also the organizational transformation and the changed perspective on data lineage and data governance up to the implementation in the Data Product.

Cloud Services

Our expertise in cloud technologies such as AWS, Azure, SnowFlake and SAP Analytics enables us to build scalable solutions. On-premise and in the cloud, the composition of the tools used is crucial to the success of the data platform, from data integration to ETL or DWA tools to the DWH System and the Reporting Solution.

Event-driven architecture & digital twin

Event-driven architectures offer an alternative to classic batch processes in a datadriven landscape. For many integration scenarios, they offer the only practical method of generic integration across various systems. For the end customer, this results in a data-driven user experience that would otherwise be almost impossible to realize or would not scale. We rely on concepts based on technologies such as Kafka, including streaming solutions, and design and implement these solutions up to RealTime scenarios and Digital Twins.
