OLTP
OLTP (Online Transaction Processing) is a type of data processing system designed to handle a large volume of short, real-time transactions, such as those in banking, e-commerce, or reservation systems. It focuses on fast query processing, data integrity, and concurrent access by multiple users, typically using relational databases with ACID properties to ensure reliability and consistency.
Developers should learn OLTP when building applications that require immediate, reliable transaction processing, such as financial systems, online shopping platforms, or booking services where data accuracy and speed are critical. It is essential for scenarios involving high-frequency updates, real-time data entry, and maintaining consistent states across distributed systems.
