Definitions for "Referential integrity"
A database concept that asserts that a value appearing in one context also appears in another, related context.
A rule defined on a key (a column or set of columns) in one table that guarantees that the values in that key match the values in a key in a related table (the referenced value). Referential integrity also includes the rules that dictate what types of data manipulation are allowed on referenced values and how these actions affect dependent values. See Also: key
A characteristic of an object that ensures that the object has references only to objects that actually exist. Maintaining referential integrity requires that, when any object is deleted, all references from other objects to the deleted object are removed.
