Bauhaus Project (computing)

The Bauhaus project is a software research project collaboration among the University of Stuttgart, the University of Bremen, and a commercial spin-off company Axivion formerly called Bauhaus Software Technologies. The Bauhaus project serves the fields of software maintenance and software reengineering.

Created in response to the problem of software rot,[1] the project aims to analyze and recover the means and methods developed for legacy software by understanding the software's architecture.[2] As part of its research, the project develops software tools (such as the Bauhaus Toolkit) for software architecture, software maintenance and reengineering and program understanding.[3]

The project derives its name from the former Bauhaus art school.[4]

History

The Bauhaus project was initiated by Erhard Ploedereder, Ph.D.[5] and Rainer Koschke, Ph.D. at the University of Stuttgart[6] in 1996.a It was originally a collaboration between the Institute for Computer Science (ICS) of the University of Stuttgart and the Fraunhofer-Institut für Experimentelles Software Engineering (IESE),[3][7] which is no longer involved.

Early versions of Bauhaus integrated and used Rigi for visualization.[8]:143–145

The commercial spin-off Axivion was started in 2005.[7]

Today, the research is done at Axivion, the Institute of Software Technology, Department of Programming Languages at the University of Stuttgart as well as at the Software Engineering Group of the Faculty 03 at the University of Bremen.

Bauhaus Toolkit

The Bauhaus Toolkit (or simply the "Bauhaus tool") includes a static code analysis tool for C, C++, C#, Java and Ada code. It comprises various analyses such as architecture checking, interface analysis, and clone detection. Bauhaus was originally derived from the older Rigi reverse engineering environment,[9] which was expanded by Bauhaus due to the Rigi's limitations.[10] It is among the most notable visualization tools in the field.[11]

The Bauhaus tool suite aids the analysis of source code by creating abstractions (representations) of the code in an intermediate language as well as through a resource flow graph (RFG).[12] The RFG is a hierarchal graph with typed nodes and edges, which are structured in various views.

The toolkit is licensed at no charge for academic use. For commercial use, the project has created a spin-off company, Axivion, to provide licensing and support under the name Axivion Bauhaus Suite.

Project funding

The Bauhaus project was funded by the state of Baden-Württemberg, the Deutschen Forschungsgemeinschaft, the Bundesministerium für Bildung und Forschung, T-Nova Deutsche Telekom Innovationsgesellschaft Ltd., and Xerox Research.[13]

Axivion

Axivion is headquartered in Stuttgart, Germany. It is a spin-off of the University of Stuttgart. The commercial-use version of the Bauhaus tool is called the Axivion Bauhaus Suite.

Reception

The Bauhaus tool suite has been used successfully in research and commercial projects.[12] It has been noted that Bauhaus is "perhaps [the] most extensive" customization of the well-known Rigi environment,[10]

The members of the project were repeatedly awarded with Best Paper Awards and were invited to submit journal papers several times.

In 2003, the Bauhaus project received the do it software award from MFG Stiftung Baden-Württemberg.[13]
