A problem where some concepts of extensible records could be useful is described in the HaskellDB project. More precisely, the problem is described in the paper downloadable from
- Chalmers version of HaskellDB (see Papers subsection on Documentation)
- which presupposes reading also paper on the Daam Leijen's original HaskellDB page (see Documentation subpage, PostScript version)
Proposals, implementations can be found on the FirstClassLabels page of Haskell' Wiki.
- HList --- a Haskell library for strongly typed heterogeneous collections includes also extensible records. Its relatedness to database programming is described in the articles, se also its possible relatedness to HaskellDB project.
- Daan Leijen: First-class labels for extensible rows. See also the description of the Haskell-like language Morrow, it is based on the concepts of the article.
