OnLine Analytical Processing (OLAP)
Online analytical processing or OLAP is an application architecture used by a company to support the analytical applications. It is not a data warehouse or database management system. The main uses of OLAP are business problems where records need to be retrieved from huge data sets. These records must therefore be totalized. To solve the problems of a modern enterprise, you need special database schemas. These schemes are array oriented and contain multi-dimensional properties. In addition, the query in this format is central. The result often resembles a multi-dimensional spreadsheet. Examples: QlikView, Qlik Sense, Business Objects, Cognos.
