Each record in a table is uniquely identified by its primary key, which also guarantees data integrity. There can only be one primary key per table, which guarantees that every record is distinct.
Conversely, a foreign key refers to the primary key in the associated table to establish a connection between two tables. By guaranteeing the validity of the link between the tables and the consistency of the data, this relationship aids in preserving referential integrity between them.
