OLAP

OLAP (Online Analytical Processing) is a technology that enables users to analyze multidimensional data from different perspectives. It allows users to perform complex calculations and queries on large datasets in real-time. OLAP systems are designed to support decision-making processes by providing fast and flexible access to data. They are used in business intelligence applications to help organizations gain insights into their operations and make informed decisions. OLAP systems typically use a multidimensional data model, which organizes data into dimensions and measures. Dimensions represent the different attributes of the data, such as time, geography, and product, while measures represent the numerical values that are being analyzed, such as sales, revenue, and profit. OLAP systems provide a variety of analytical functions, such as drill-down, roll-up, slice-and-dice, and pivot, which allow users to explore data in different ways.
