Haskell's most popular database module is HBC

✓ Haskell's most popular database module is HDBC. 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 a number of backend SQL databases.

✓ 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. As DBI requires DBD in Perl, HDBC requires a driver module beneath it to work. These HDBC backend drivers exist: PostgreSQL, SQLite, and ODBC (for Windows and Unix/Linux/Mac). MySQL is the most popular open-sourced database, and there are two drivers for MySQL: HDBC-mysql (native) and HDBC-odbc (ODBC). MySQL users can use the ODBC driver on any MySQL-supported platform, including Linux. An advantage of using ODBC is that the syntax of the SQL statement is insulated from the different kinds of database engines. This increases the portability of the application should you have to move from one database to another. The same argument for preferring ODBC applies for other commercial databases, such as Oracle and DB2
