Nevertheless there are several shortcomings of the current proposal stemming from the adaption of concepts of object-oriented programming and a lack of formalization. In this paper we present a formalization of the ODMG model and the OQL query language that is used in the CROQUE project as a basis for query optimization. An essential part is a complete, formally sound type system that allows us to reason about the types of intermediate query results and gives rise to fully orthogonal queries, including useful extensions of projections and set operations.</dcterms:abstract> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/6294"/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/36"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T16:11:12Z</dc:date> <dc:contributor>Scholl, Marc H.</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T16:11:12Z</dcterms:available> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/36"/> <dcterms:rights rdf:resource="https://rightsstatements.org/page/InC/1.0/"/> <dc:rights>terms-of-use</dc:rights> <dcterms:title>The CROQUE-Model : Formalization of the Data Model and Query Language</dcterms:title> <dcterms:issued>1996</dcterms:issued> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/6294/1/CROQUE_model.pdf"/> <dc:contributor>Riedel, Holger</dc:contributor> <dc:language>eng</dc:language> <dc:creator>Scholl, Marc H.</dc:creator> <dc:format>application/pdf</dc:format> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/6294/1/CROQUE_model.pdf"/> </rdf:Description> </rdf:RDF>
