multiple value (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. [Confirm, clarify?] Last updated: 1995-10-30
