Final answer:
OLTP is used to facilitate and manage transaction-oriented applications such as point-of-sale and data entry processing.
Step-by-step explanation:
OLTP (Online Transaction Processing) is used to facilitate and manage transaction-oriented applications, such as point-of-sale, data entry, and retrieval transaction processing. It is designed for fast and efficient transaction processing, where multiple users can access and update the database simultaneously.
OLTP databases are optimized for handling a high volume of small, granular transactions, such as inserting, deleting, or updating records. They prioritize data integrity and immediate response time.
For example, when you make a purchase using a credit card, OLTP systems handle the transaction by verifying the card details, deducting the amount from the available credit, and updating the financial records.
