OLTP (Online Transaction Processing) systems are designed to handle large volumes of routine, structured transactions. They are used at the operational level of an organization to capture and store transactional data (e.g., sales, payroll, inventory). OLAP (Online Analytical Processing) systems, on the other hand, are used for complex analysis of data, often to support decision-making at the managerial or strategic level. OLAP tools allow users to perform multidimensional analysis of aggregated data, supporting semistructured or unstructured decisions. Therefore, all the choices correctly describe the primary differences between OLTP and OLAP systems.
