Abstract
In this work, a new external schema definition methodology for object oriented databases (OODB) that solves some of the problems of existing methodologies is presented. In particular, this new methodology avoids the need for generating derived classes that are not directly used in the defined external schema. Also, it offers a way of integrating and reusing different external schema definitions.
