Object-Oriented GALILEOfrom the representation type; b) the notion of type hierarchies; c) and object-oriented view of databases, where objects are the only values that can be created, destroyed, and updated. Examples will be given to show how the conceptual language Galileo might be modified to become a strongly typed, object-oriented database language.
