The term "olap" likely refers to "OLAP," which stands for Online Analytical Processing. It is a computer-based approach used for querying and analyzing data that is stored in a database. OLAP enables users to perform multidimensional analysis of business data, providing the capability for complex calculations, trend analysis, and sophisticated data modeling.
The acronym "OLAP" comes from the early 1990s, combining "Online" (referring to the operational aspect of querying and real-time analysis) with "Analytical" (indicating that the purpose is to analyze data) and "Processing" (meaning the manipulation and management of data).
