In fact, an OLAP server is typically the middle, analytical tier of a data warehousing solution. Common uses of OLAP include data mining and other business intelligence applications, complex analytical calculations, and predictive scenarios, as well as business reporting functions like financial ...
OLAP Operations in Data Mining OLAP is a widely spread technology belonging to Business Intelligence processes developed to coordinate and analyze vast amounts of data. OLAP databases are stored in the form of multidimensional cubes where each cube comprises the data supposed relevant by a cube admin...
OLAP mining is a mechanism which integrates on-line analytical processing ( OLAP ) with data mining so that mining can be performed in different portions of databases or data warehouses and at different levels of abstraction at user's finger tips. With rapid developments of data warehouse and ...

Was ist Datenmodellierung in OLAP? Datenmodellierung ist die Darstellung von Daten in Data Warehouses oder OLAP-Datenbanken (Online Analytical Processing). Die Datenmodellierung ist für die relationale Online-Analyseverarbeitung (ROLAP) unerlässlich, da sie Daten direkt aus der relationalen Datenbank...
