Question

BlackTom AI · Accepted Answer

The question asks whether a referential integrity constraint specifies that the existence of an attribute in one table depends upon the existence of a foreign key in the same or another table.
Option 1: True. Referential integrity indeed ties the values in a foreign key column to the primary key (or candidate key) values in the referenced table. This means that the existence and validity of the foreign key value depend on corresponding existing values in the referenced table (or the possibility of it being NULL, depending on the constraint). In that sense, the relational linkage is established through the foreign key in one table referencing a key in another table, which aligns with the idea that an attribute's valid state depends on the foreign key relationship.
Option 2: False. This would be incorrect because it ignores the core mechanism of referential integrity: foreign keys enforce consistent references to related rows in another table. If there were no such dependency, the database could permit orphaned references, breaking relational integrity. The statement, as a description of the dependency created by referential integrity, does not accurately portray the mechanism, so this option mischaracterizes the concept.
In summary, understanding referential integrity centers on foreign keys ensuring that referenced values exist in the related table (or are permitted to be NULL), which supports treating the statement as true rather than false.
