Question

Quizplus · Accepted Answer

Relational databases use foreign keys to represent the relationships between tables. Foreign keys are columns that refer to the primary key of another table, creating a link between them. This enables data to be stored in separate tables but still maintained in a structured and organized manner. File systems, metadata, primary keys, and trees are also used in databases, but they do not specifically represent relationships between tables.
