The most important characteristic of an entity is its primary key, used to uniquely identify each entity instance.

<h3>What is primary key?</h3>

A column, or group of columns, known as a primary key in a table uniquely identifies each row of data. For instance, CustomerNo, which displays the ID numbers assigned to individual customers.

The primary key of a relational database, often called the primary keyword, is a key that is unique to each entry. It is a unique identification number, much like the ones on a driver's license, phone with an area code, or car (VIN). A relational database's primary key must always be distinct.

Thus, it is a primary key.
