Tehingutöötlus, also known as transaction processing, refers to the system or method used to manage and execute a series of operations, often financial in nature, in a way that ensures data integrity and consistency. This involves capturing, validating, and storing data related to each individual transaction. The primary goal of transaction processing is to ensure that transactions are processed accurately and reliably, preventing data corruption or loss.

There are two main types of transaction processing systems: batch processing and online transaction processing (OLTP). Batch processing involves collecting a group of transactions over a period and processing them together at a later time. This is often used for tasks like payroll or end-of-day accounting. Online transaction processing, on the other hand, handles individual transactions in real-time as they occur. This is common in systems like point-of-sale terminals, banking ATMs, and e-commerce platforms where immediate response is crucial.

Key principles of transaction processing include atomicity, consistency, isolation, and durability, collectively known as ACID properties. Atomicity ensures that a transaction is treated as a single, indivisible unit of work; either all its operations are completed, or none are. Consistency guarantees that a transaction brings the system from one valid state to another. Isolation ensures that concurrent transactions do not interfere with each other. Durability means that once a transaction is committed, its changes are permanent and will survive system failures. Effective tehingutöötlus is fundamental for the reliable operation of most modern information systems.
