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.

Petechiae

A Data Modeling Methodology for the Design and Implementation of Information Systems corresponding database system software can be systematically derived, and it tests and demonstrates the adequacy of such a model for defining software systems in general. The design methodology introduced combines techniques from data modeling, formal specifications, and software engineering.

Demonstrate

Handling Constraints and their Exceptions: An Attached Constraint Handler for Object-Oriented CAD Daountered in CAD environments, discusses the problems of dynamic constraint definition and deferred evaluation, and based on this discussion, introduces the design and implementation details of the constraint and exception handler.

However, the notion of “object-orientation” in the context of database systems is unfortunately still widely unclear and means different things to different peo
