Quizplus · Accepted Answer

A foreign key is a column in one table that references a primary key in another table. This creates a relationship between the two tables, allowing data to be queried and manipulated across both tables. A secondary key is another index used to speed up queries, but it is not related to another table. Referential key and meta key are not commonly used terms in database design.
