Abstract
A presentation format generation strategy for composite reports is proposed for object-oriented databases. The reports can have nested formats (in extended non-first-normal-form). The problem of presentation view generation over object-oriented conceptual/external view is discussed. The presentation format should vary at run time, depending on repeating groups and data arrangement. A new format composition scheme is proposed, based on the idea of dynamic co-referring objects, which uses an object-oriented data model extended to the presentation layer. As important features, various composite reports can easily be derived from databases, and dynamic format modification is possible interactively, even after retrieving the data.<>
