Abstract
An object-oriented data model, MORE, in which the database specification facilities have been extended so that users can specify an object with various structures is presented. The structure of an object is changed by passing messages. MORE also provides a classtype, a user-defined type for classes with similar structures, in order to simplify the specification of class descriptions. The system generates operations useful for the classes by referring to a corresponding classtype. A prototype system and an example application are described
