How deeply does Object-Oriented Software Design in C++ cover name-value pair?

Explains map key and value typing, then implements heterogeneous values with variant and pair matching.

Name-value pair

As explained in Object-Oriented Software Design in C++

A name-value pair is a data association in which an identifying name or key corresponds to a value.

A name–value pair associates an identifying key with its corresponding value. An STL map stores these pairs, using the key to retrieve the value; all keys share one datatype, while values may use another. section 2.3.4

Searching by associated attributes

A catalogue query can request {KIND: fiction, LAST: 'KING', GENRE: horror}; matching pairs find Carrie and It: A Novel even when other attributes differ.
