Online Transaction Processing (OLTP)

Online Transaction Processing (OLTP) is a type of database system designed for managing transaction-oriented applications. These systems are expected to handle user requests and process transactions in real-time. Examples of OLTP applications include online banking, shopping, and order entry.

OLTP has also been used to refer to processing in which the system responds immediately to user requests. An automated teller machine (ATM) for a bank is an example of a commercial transaction processing application. Online transaction processing applications have high throughput and are insert- or update-intensive in database management.

The key goals of Online Transaction Processing (OLTP) applications include:

1.???? High Availability: Ensuring the system is always available to process transactions, minimizing downtime and disruptions.

2.???? Fast Response Times: Providing quick responses to user requests to maintain a smooth and efficient user experience.

3.???? Data Integrity: Maintaining accurate and consistent data through mechanisms like ACID (Atomicity, Consistency, Isolation, and Durability) properties.

4.???? Scalability: Supporting a growing number of transactions and users without compromising performance.

5.???? Concurrency Control: Managing multiple transactions simultaneously without conflicts or data corruption.

6.???? Reliability: Ensuring the system can handle failures gracefully and recover quickly to prevent data loss.
