Answer:
What is the function of primary keys? Primary keys facilitate searching and sorting because they act as unique identifiers.
Explanation:
In Database Managements Systems, a key is a field in a database that is used to sort, identify or retrieve records in a relation table. A Primary key is column or group of columns used to uniquely identify each row on a table, and the same value cannot be repeated on the table. This makes it very easy and fast to retrieve data without having to search each row in the database.
