OLAP (Online Analytical Processing) is a BI reporting system that uses extensions to SQL to carry out multidimensional analysis of data. It enables users to analyze large volumes of data from various perspectives, such as time, geography, product, and customer, among others. Cluster analysis, regression analysis, and RFM analysis are statistical methods used to analyze data, but they do not involve using extensions to SQL. PHP is a server-side programming language used to develop web applications, but it is not directly related to BI reporting systems.
