A transaction processing system is an integral component of today’s businesses, handling financial transactions and helping organizations maintain accurate and up-to-date records. These systems are designed to manage transaction records that emerge from various business activities and ensure the integrity and efficiency of routine financial transactions by managing data entry, updating, and retrieval while maintaining important records. There are two types of transaction processing systems: real-time processing, which captures transactions quickly and updates databases within milliseconds, and batch processing, which involves collecting data over a period and processing it all at once. OLTP (Online Transaction Processing) systems handle many short online transactions, such as insert, update, and delete, while OLAP (Online Analytical Processing) systems focus on retrieving data for analysis and reporting. ACID compliance is a mission-critical database requirement that ensures the data integrity of operations even in high-concurrency environments.
