In literature, it is common knowledge that semantic data modelling is well established. It is the goal of this paper to review this opinion critically. By means of an empirical study which investigated data administration in Styrian industrial enterprises with more than 1000 employees it will be shown that even in companies of that size semantic data modelling is not commonly used. Only around one third of the enterprises model their data. The main reason for this is the increasing use of packaged software.
