Abstract
Constructs for an object-oriented non procedural data base
manipulation language called OSQL/N are presented. The major feature
is that the language allows for conditional manipulation of an object
together with a quantified set of its related objects. The constructs
required for this were borrowed from a language called SQL/N, which is
implicitly object-oriented, but which was originally developed as an
attempt at a more natural relational data base language. The
constructs behind SQL/N are much more suited to object-oriented data
bases, and the OSQL/N language structure, as a result, allows for
incorporation of the whole array of quantifiers that are commonly used
in natural language, that is, the natural quantifiers.
