Integrity involves ensuring that data is not improperly modified or deleted. It helps maintain the accuracy and trustworthiness of data, such as ensuring customer information in a database is not lost or corrupted.

What could happen if data integrity is compromised?

If data integrity is compromised, such as an IT admin accidentally deleting a customer account, it can lead to significant problems, like the inability to retrieve customer information when needed for support.
