WebA data type defines a set of values. A reference to a data type specifies the set of values that can occur in a given context. A data type is associated with each value retrieved … WebA data specification is an equational specification, in which sorts denote data types. The semantics of a sort is a non-empty set. The elements of the semantics of a sort are described by its constructors, whereas the mappings are functions defined on the semantics of sorts. The equations (axioms) describe equational properties of functions and ...
