On-line analytical processing Abelló Gamazo, Alberto Romero Moral, Óscar Àrees temàtiques de la UPC::Informàtica::Sistemes d'informació::Bases de dades Data warehousing OLAP Gestor de dades On-line analytical processing (OLAP) describes an approach to decision support, which aims to extract knowledge from a data warehouse, or more specifically, from data marts. Its main idea is providing navigation through data to non-expert users, so that they are able to interactively generate ad hoc queries without the intervention of IT professionals. This name was introduced in contrast to on-line transactional processing (OLTP), so that it reflected the different requirements and characteristics between these classes of uses. The concept falls in the area of business intelligence.
