Abstract
COOL is a composite object-oriented
declarative language for use as an extension to SQL with
relational databases that have a distinct object orientation. COOL is
unique in that it permits unambiguous specification and quantification
of relationships by means of a construct called a genitive relation.
The notion of composite object concentration with COOL is also
introduced. The paper describes advanced COOL constructs, for which
there are no SQL equivalents, for definition and extraction of
composite objects from a relational data base. These
constructs permit specification, concentration and manipulation of
composite objects of great complexity. It is also shown how COOL uses
these constructs with the inheritance aspects of generalization or
IS-A type hierarchies.
