On-line Analytical Processing (OLAP)
OLAP is software for manipulating multidimensional data from a variety of sources that has been stored in a data warehouse. The software can create various views and representations of the data. OLAP software provides fast, consistent, interactive access to shared, multidimensional data. These systems are used to discover trends, analyze critical factors and perform statistical analysis. The term OLAP was introduced in 1993 by Dr. E.F. Codd. Check the Guide to OLAP Terminology from the OLAP Council.
