Abstract	In this paper we motivate and present a data model for conceptual design of structural and behavioural aspects of databases We follow an object centered design paradigm in the spir it of semantic data models The speci cation of structural aspects is divided into modelling of object structures and modelling of data types used for describing object properties The speci cation of object structures is based on an Extended Entity Relationship EER model The speci cation of behavioural aspects is divided into the modelling of admissible database state evolutions by means of temporal integrity constraints and the formulation of database trans actions The central link for integrating these design components is a descriptive logic based query language for the EER model The logic part of this language is the basis for static constraints and descriptive action speci cations by means of pre and postconditions A tem poral extension of this logic is the speci cation language for temporal integrity constraints We emphasize that the various aspects of a database application are speci ed using several appro priate but yet compatible formalisms which are integrated by a unifying common semantic CR
