MUSTARD (MultiUser Server That Accesses Relational Databases)
is a powerful xtra for the multiuser server that allows director applications to easily perform database queries and updates through the multiuser server. The big advantage with this strategy is that you do not need to distribute a specialized xtra with your director applications. All queries are performed through the multiuser server.

MUSTARD will work with any ODBC-compliant database. Data can be stored and returned in any director format, including lists, making it easy to access and manipulate data.
