This volume presents the proceedings of the sixth International Conference on Advanced Information Systems Engineering, held in Utrecht, The Netherlands, in June 1994. The 30 contributions by researchers from industry and academia and by ambitioned professionals were selected from a total of 130 submissions after a highly competetive refereering process. The papers are organized in sections on development process support, workflow management, management and quality, object-oriented requirements engineering, behavioural modelling, advanced development tools, reuse, formal IS modelling, method engineering, and advanced database engineering. In total, the volume gives a thorough state-of-the-art report on current research and advanced applications in advanced information systems engineering.
