HDBC provides an abstraction layer between Haskell
programs and SQL relational databases. This lets
you write database code once, in Haskell, and have
it work with any number of backend SQL databases
(MySQL, Oracle, PostgreSQL, ODBC-compliant
databases, etc.) HDBC is modeled loosely on
Perl's DBI interface, though it has also been
influenced by Python's DB-API v2, JDBC in Java,
and HSQL in Haskell.
