Generic multiset programming for language-integrated querying
This paper demonstrates how relational algebraic programming based on efficient symbolic representations of multisets and operations on them can be applied to the query sublanguage of SQL in a type-safe fashion. In essence, it provides a library for naïve programming with multisets in a generalized SQL-style fashion, but avoids many cases of asymptotically inefficient nested iteration through cross-products.
