Which system performs and records routine transactions at an operational level?

Transaction Processing Systems (TPS) are specifically designed to handle and record routine transactions that occur at the operational level of an organization. These systems play a critical role in managing day-to-day operations by capturing and processing transactions such as sales orders, payroll, inventory management, and other routine business activities.

TPS ensures accuracy and efficiency in transaction handling, providing various functionalities including data entry, transaction processing, and storage of data for further reporting and analysis. The immediate nature of TPS allows organizations to function smoothly, maintaining records for both operational needs and netting out periodic reports that inform higher management.

In contrast, other systems like Executive Support Systems (ESS), Knowledge Work Systems (KWS), and Decision Support Systems (DSS) serve different purposes. ESS focuses on high-level information management for executives, helping them make strategic decisions. KWS supports knowledge workers in creating and integrating new knowledge, while DSS is designed to aid in decision-making with analyses and simulations. None of these systems concentrate on the routine transaction processing that is the hallmark of TPS, emphasizing the unique role of Transaction Processing Systems in operational functionality.
