About Tobias

We are a service company specializing in consulting and development in the field of databases (DB), Business Intelligence (BI) and Artificial Intelligence (AI). Since 2014, we have been working for companies from a wide variety of sectors. Customers from the pharmaceutical, healthcare, trade, energy, hosting, telecommunications, banking and other sectors appreciate our in-depth expertise in these areas. In a rapidly developing market, we offer our customers the latest developments in Microsoft SQL Server, architecture topics in the data warehouse area (e.g. Data Vault 2.0) and artificial intelligence in order to make meaningful predictions based on the collected data or to calculate and predict events in advance.
Through continuous development of our employees through training and rotation in the individual projects, we can offer you external know-how for your database projects (whether warehouse, processing of big data, analyses, evaluations (reporting)). Be it due to a lack of resources where you need short-term support, building or expanding existing know-how through knowledge transfer during the project phase by our employees or in the development of new structures, conversion and also in the optimization of existing systems.
Please do not hesitate to contact us.

    Replacing IBM Congnos with PowerBI as a global reporting solution. The basis is initially still an SAP/HANA that feeds an Azure Analysis Services platform with OLTPs. In the next step, this construct is to be replaced by Azure Data / Azure Delta Lake as a data platform. This means that SAP/HANA as well as SAP/BW are completely eliminated for the customer.
