COOL is a composite object-oriented declarative data base language for use with Nsup2F relational data bases. COOL uses a construct called a genitive relation to enable unambiguous specification and quantification, both conventional and natural, of relationships.
A genitive relation is used in a manner corresponding to the genitive case with noun objects in natural language. Instead of formal genitive relation name syntax, a genitive case alias can be used to promote ease of expression construction.
