Answer 1

Answer:

Primary and foreign keys. Primary and foreign keys define the relational structure of a database. These keys enable each row in the database tables to be identified, and define the relationships between the tables.

A DBMS plays a crucial role in both the creation and management of data. Without a database management system, running and managing data effectively is not possible. Serving as the intermediary between the user and the database, a DBMS provides users access to files stored in a databasE

Choosing a primary key is one of the most important steps in good database design. A primary key is a table column that serves a special purpose. Each database table needs a primary key because it ensures row-level accessibility.
