oRestE (odbc Rest Erlang) is a scalable and flexible way to share you databases via REST web services:

• the SQL statements can have parameters

   http://localhost:8000/moodle/llab/user.xml?name=matteo

http://localhost:8000/moodle/llab/user.csv?name=matteo


http://localhost:8000/moodle/llab/user.txt?name=matteo&lengths=30

• the output can be XML or CSV ot XLS or fixed TEXT formats.
  

oRestE built on top of ERLANG, MOCHIWEB and WEBMACHINE (webmachine.pdf)

You just need to add in a configuration file a SQL statement like the following

  {user,
        "select *
        from
                mdl_user
        where
                username='{username}'"
  }.
