OLAP Cube

An OLAP (Online Analytical Processing) cube is a multidimensional data structure used for fast analysis of business data, enabling complex queries and aggregations across multiple dimensions like time, geography, and product categories. It organizes data into a format optimized for analytical operations such as slicing, dicing, drilling down, and rolling up, typically sourced from data warehouses or transactional databases. This technology is fundamental in business intelligence and data analytics for supporting decision-making processes.
