The full form of OLTP is Online Transactional Processing. It is a type of data processing that manages and facilitates transaction-oriented applications generally for data entry and retrieval in real-time. Furthermore, OLTP systems are crucial for businesses that require immediate and accurate data processing to support their daily operations. Moreover, the development of OLTP makes it easy to use for frontline workers such as cashiers or for customer self-service applications like e-commerce and online banking.

What are the Characteristics of OLTP?
In addition, the characteristics of OLTP are as follows:
- Concurrency Control: OLTP systems must manage multiple transactions altogether without conflicts. Additionally, concurrency control guarantees that transactions preserve the integrity of data.
- Transaction Management: Moreover, OLTP systems highlight the processing of individual transactions. Each transaction applies a small, well-defined set of procedures, and the system makes sure that transactions are in their entirety or not at all.
- Data Normalization: OLTP databases are created with normalized data structures to minimize redundancy and maintain data consistency. This especially makes it efficient for transactional processing but may differ from data warehousing approaches.
- Fast Response Time: Apart from this, OLTP systems need low latency and fast response times to support real-time interactions. Moreover, users expect quick responses when entering or retrieving data from the system.

What are the Disadvantages of OLTP?
Some of the disadvantages of OLTP are –
- The system is at risk of being vulnerable to cyber-attacks or unauthorised access
- Should there be a problem with the equipment or a power outage, there’s a chance that data could be lost
- Handling multiple requests at the same time can be challenging
- An overload could cause servers to become unresponsive
What are the Examples of OLTP?
The examples of OLTP systems are as follows:
- ATMs and online banking applications
- Credit card payment processing in-store or online
- Order entry systems in both retail and back-office environments utilize transaction processing to efficiently handle customer orders.
- Different online bookings such as ticketing and reservation systems, rely on instantaneous and accurate reservation confirmations.
- Record-keeping functions, spanning health records, inventory control, production scheduling, claims processing, customer service ticketing, and numerous other applications, heavily depend on maintaining real-time and accurate data.
