Applications
Declarative database management
Such systems can achive more type safety (compared to direct SQL handling).
HaskellDB
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)
HaskellDB uses its own extensible record sytem, but see also HaskellDB#Future.
CoddFish
CoddFish is another declaratice, type safe database system. As for extensible record system, it uses HList --- a Haskell library for strongly typed heterogeneous collections.
