【 摘 要 】

This paper presents, fromthe author's per-spective, the problems that occur in prac-tice during data modelling. The author'sexperiences are a result of a considerablenumber of projects which he carried outin the framework of his consultancy roleat USU Softwarehaus in Moglingen (Ger-many).These projects concerned the followingthemes: Corporate Datamodelling Comparing Datamodels Project (Application)- related Datamodelling.In all cases, E/R-notation was the chosenrepresentation-form. From these experi-ences, the author formed an impression ofthe problems that occur in practice whendening a data model. These problemshave, however, also led to the author's in-creased interest in knowledge representa-tion, in turn leading to his usage of KR-methods in practice. This has shown itselfto be quite eective.Sections 2 and 3 briefiy illustrate the recommendations and the experiences arising from their usage in projects.
