MDX for Creating Business Logic (SQMDX)

Kursbeschreibung Kurstermine
 

Kursüberblick

MDX wird verwendet, um Business Logic für multidimensionale Cubes in SQL Server Analysis Services zu kreieren. In diesem Kurs lernen die Teilnehmer MDX Berechnungen und Named Sets (=Gruppen von Elementen zur wiederholten Verwendung in MDX Abfragen) zu verstehen und zu erzeugen. Dieses Seminar ist relevant für SQL Server 2014, 2012 und 2008.

Der Kurs MDX for Creating Business Logic ist ein Einführungskurs in MDX.

Zielgruppe

Das Seminar richtet sich an Entwickler und BI-Profis, die multidimensionale Cubes in SQL Server Analysis Services entwickeln und/oder supporten.

Voraussetzungen

Analysis Services Kenntnisse

Grundlagen zu multidimensionalen Objekten wie Cubes, Dimensions, Hierarchies, Levels, Members und Measures
