in 1965, and started working at Philips at the department of Commercial Efficiency Research. From 1968 to 1970 he has been director of the educational institute "The Dutch Centre for Business and IT". In 1970 he moved to the Control Data Corporation
, a pioneer in the field of computer science
with the European headquarters in Brussels in Belgium. At Control Data early 1970s Nijssen started with fact-based modeling and developed NIAM, a fact based business practice and notation. During this time, he was also associated with several academic institutions and international standards organizations. He has served as founding Chairman of IFIP WG 2.6 (Databases), member of IFIP WG 8.1 (Information Systems) and member of ISO TC97/SC5/WG3 (Conceptual Schema).
