Welcome to VSIS

VSIS was part of the department’s focus on „Complex Systems Engineering“ (CSE) and consisted of two independent sub-groups which do research and teaching in different but thematically related topic areas. The „Distributed Systems“ (VSYS) group was headed by Prof. Dr. Winfried Lamersdorf, the „Databases and Information Systems“ (DBIS) group was headed until 2023 by Prof. Dr.-Ing. Norbert Ritter.

In the domain of „Distributed Systems“ conceptual design, prototype implementation as well as use and application of system software to support open distributed applications were mainly considered. The group of „Databases and Information Systems“ was primarily engaged in concepts for modeling, architectures and implementations of data management in complex software systems and applications. As the complexity of current applications of both working groups is essentially determined by problems of heterogeneity, distribution and complexity, both fields complement one another and overlap thematically.

Exemplary collaborative fields of work were, e.g., actual system technologies, such as Service Oriented Architecture (SOA) and Web Services as well as cloud computing. This includes dealing with various forms of (distributed business) processes (workflows) and various aspects of Cloud and Grid Computing on the basis of increasingly powerful and more widespread information and communication technologies such as the Internet.
