Data Engineering


Data Engineering

Our data engineering division focuses on the data usage within the company. We cover the entire "data value chain" from the creation of data in the core applications through its integration and refinement layers up to the usage of data in the business processes, business applications and its analysis.

As bridge builders between the Business and IT departments, we bring together the needs of the users and the capabilities of your IT. We stand for efficient and sustainable solutions. Our understanding of business processes, methodologies and various technologies makes us the ideal partner in complex projects.

Data Integration

In many companies, data is the foundation for success. It is stored in different systems and used in different ways. The integration and processing of data is usually driven in a data warehouse.

Different types of data requires different technologies and architectures. In most cases, there is a distinction between operational and analytical use of information. ​ The Callista group has extensive experience in the design and implementation of various platforms such as ​

  • Data warehouses
  • Big data platforms
  • Operational and enterprise information hubs

In numerous projects we have built such platforms and successfully integrated them with core applications.

Data Presentation

The use of data for operational, tactical and strategic decisions requires solid BI platforms. Information can be presented in very different ways and processed further. A homogeneous preparation and presentation of key performance indicators are the basis for reporting. They are often the decisive success factor, especially in grown environments with different technologies.

In addition, the flexibility and autonomy of the users (self service) is becoming increasingly important. However, this must be managed, which is usually underestimated. ​ We fully support our customers in their data usage in ​

  • BI Landscapes
  • Reports, Dashboards and Cockpits
  • Self-Service BI
