DICE: Declarative Integrity Constraint Embedding Into the Object Database Standard ODMG-93

Abstract In this paper we present a new approach for embedding integrity constraints into object-oriented database systems (OODBS), which can not be specified implicitly by structure or explicitly by keywords of the system. To take those integrity constraints into consideration they have to be integrated into the behavioral part of an object-oriented schema. This paper gives a survey of the existing proposals for this integration and presents a new one, DICE, to overcome the drawbacks of the reviewed solutions. As an example we describe the integration of DICE into object-oriented schema according to ODMG-93.
