Here you will find information on what we are doing in the areas of databases, information systems, process design and modeling, and IT architectures, what we have to offer, how you can contact us, how to reach us, etc.

Our work currently centers around a variety of issues arising in and from present-day mobile as well as stationary systems that generate, store, analyze, and process large amounts of data. Examples of such systems include data warehouses, hospital information systems, and applications (such as search engines) based on the Web. Specific issues studied include the design of such systems, consistency of transactional services, data integration and unification, data curation and monetization, the design and analysis of community-based business processes, but also questions of how to design suitable IT landscapes (such as Web-oriented architectures or reliable, secure clouds) comprising such systems.
