What is the role of automatic value incrementation in database management systems?

Auto-increment in database management systems is used to generate unique record identifiers, most often for primary keys. This simplifies creating new records, as there is no need to manually specify a unique identifier.

Role of auto-increment:

• Ensures key uniqueness without additional logic.
• Simplifies data insertion by automatically assigning the next available number.
• Helps maintain data integrity and relationships between tables.

For example, in a users table, the id field can be auto-increment, and when adding a new record, the DBMS will automatically assign the next number.
