OLTP vs OLAP: The Two Pillars of Modern Data Systems

Online Transaction Processing (OLTP) handles fast, reliable day-to-day transactions like payments and bookings, while Online Analytical Processing (OLAP) analyzes large historical datasets for reporting and forecasting. OLTP uses row-oriented storage for quick record updates, whereas OLAP uses columnar storage for efficient aggregations. Understanding these differences is crucial for designing effective data architectures.
