View mechanisms, widely used in the relational databases, pose new questions in the object model which captures much more semantics. In this paper, we will focus on inheritance and inter-objects relationships, two main semantic aspects of the object model. Like in the relational model, most of the current works about object-oriented views assume a fine granularity of the views. View classes are defined by the application of a query operator to one or two classes of the base schema. View schemas are defined as sets of view classes. These sets are explicitly chosen by the database administrator.
