FQL -- The Design and Implementation of a Functional Database Query Language

摘要

FQL is a database query language in the area of functional programming systems and has been designed and developed in an attempt to provide a powerful formalism for the expression of complex database queries. There is no notion of data currency; full computational power is provided; complex queries may be developed incrementally; and the language itself is independent of any database management system. This document describes the syntactic and semantic rudiments of FQL through a set of examples. (Author)
