See http://trac.haskell.org/haskelldb for the latest information on HaskellDB.
HaskellDB is a combinator library for expressing queries and other operations on relational databases in a type safe and declarative way. All the queries and operations are completely expressed within Haskell, no embedded (SQL) commands are needed.
The guide HaskellDB - Getting Started explains how to install HaskellDB and run a simple test program. This needs to be updated for the current version of HaskellDB.
The HaskellDB guide to hacking is a linked HaskellDB guide with the most common uses of HaskellDB explained. This needs to be updated for the current version of HaskellDB.
You can find API documentation for the latest release on the HaskellDB page in HackageDB.
