multiple value
     
         (MU) A one-to-many relationship between entries in
        a database, for example a person may have an address field
        which spanned multiple records (with different indexes).
        Multiple values are a non-{relational} technique.
     
        MUs have recently been made available in {DB2}, despite the
        product being so heavily influenced by {Codd's Laws} of
        {relational databases}.
