Universal relation assumption
From HandWiki
Short description: Database theory
The universal relation assumption in relational databases states that one can place all data attributes into a (possibly very wide) table, which may then be decomposed into smaller tables as needed.[1]
However, the assumption that a single large table can capture real database designs is often plagued with a number of difficulties.[2] The "nested universal relation" model has attempted to address some of the problems and offer improvements.[3]
