OLTPjärjestelmät

OLTPjärjestelmät, or Online Transaction Processing systems, are computer systems designed to handle a large number of concurrent transactions that are short and atomic. These systems are optimized for data entry and retrieval, and are commonly used in applications that require real-time processing of business transactions. Examples include order entry, banking transactions, and retail sales. The primary goal of OLTP systems is to ensure data integrity and availability by supporting high volumes of read and write operations with minimal latency.

Key characteristics of OLTP systems include their focus on speed and efficiency, the atomic nature of transactions (all or nothing), and the need for high availability and concurrency. They typically involve a large number of users interacting with the system simultaneously, making performance and scalability crucial. Data consistency is paramount, and OLTP systems employ mechanisms like locking and transaction logs to maintain it. While OLTP systems excel at processing individual transactions, they are not designed for complex analytical queries or reporting, which are the domain of OLAP (Online Analytical Processing) systems. The design emphasizes short, fast transactions over lengthy, complex ones.
