ConQuer-92 -- The revised report on the conceptual query language LISA-D
H. A. Proper
TL;DR
This paper formally defines ConQuer-92, a conceptual query language used in InfoAssistant and InfoModeler, focusing on its syntax and semantics, with implementation details to be addressed separately.
Contribution
It introduces and formally defines ConQuer-92, a new conceptual query language for information systems, detailing its structure and intended applications.
Findings
Formal definition of ConQuer-92 provided
Language supports derivation rules and textual constraints
Implementation in SQL-92 is planned for future work
Abstract
In this report the conceptual query language ConQuer-92 is introduced. This query language serves as the backbone of InfoAssistant's query facilities. Furthermore, this language can also be used for the specification of derivation rules (e.g. subtype defining rules) and textual constraints in InfoModeler. This report is solely concerned with a formal definition, and the explanation thereof, of ConQuer-92. The implementation of ConQuer-92 in SQL-92 will be treated in a separate report.
