Ignite UI API Reference

ig.OlapXmlaDataSource

ig.OlapXmlaDataSource_image
The igOlapXmlaDataSource component handles the communication between a JavaScript client application and a Microsoft® SQL Server Analysis Services (SSAS) server configured with the msmdpump.dll HTTP data provider. It exposes a user-friendly way for obtaining data from Microsoft SQL Server Analysis Services (MS SASS) – you do not have to possess any particular knowledge of Multidimensional Expressions (MDX) or XML for Analysis (XMLA) in order to get the data from an SSAS server. The igOlapXmlaDataSource generates the necessary MDX queries based on the commands it is given. The igOlapXmlaDataSource is usually used with one or more of the Ignite UI widgets capable of visualizing and interacting with OLAP data, e.g. igPivotView™ or igPivotGrid™.
