database (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.
