Dynamic object bases differ from classical database models in their integrated description of structure and behaviour of objects. The arguments for introducing the different schema levels for database applications hold for object bases, too, and ma

We justify why IDIOMS does not use an operating system, and why a Data Storage Description Language (DSDL) is used to control data placement. Our implementation extends the SQL2 informatio

Sarah Straub,Iris Baumgardt,Dirk Langete queries which clearly state what it is they want to know and the answers to queries are often misleading. These problems can be remedied by the use of modal logic which allows questions to be asked about what . be true and what . be true, rather than simply about what . true..This paper presents

For the most part, however, such tools only permit the structure of the data to be described, whereas much of the meaning of the model of data required by the application can only be expressed as constraints.

Such integration can provide transparency of heterogeneity in two different situations: when preexisting schemas of separate databases are integrated into a single unified global schema; and
