Online Transaction Processing
Online Transaction Processing (OLTP) is a database management system concept focused on processing high volumes of real-time transactional data, such as sales, orders, or financial transactions. It emphasizes fast query processing, data integrity, and concurrent access by multiple users, typically using normalized database schemas to minimize redundancy and ensure consistency. OLTP systems are designed for operational efficiency, supporting day-to-day business operations with immediate data updates and retrieval.
Developers should learn OLTP when building applications that require real-time data processing, such as e-commerce platforms, banking systems, or reservation systems, where quick response times and data accuracy are critical. It is essential for scenarios involving frequent insert, update, and delete operations, as it ensures transactional integrity through ACID (Atomicity, Consistency, Isolation, Durability) properties, preventing data corruption in multi-user environments.
