About SSAS
 AS is a server-based platform for OLAP and data mining.
 Tools - BIDS, SSMS
 Query language – Multidimensional Expressions or MDX;
for Data Mining - Data Mining Extensions or DMX
 MDX Query:

, [Product].[Category].Members ON ROWS
FROM [Adventure Works]
WHERE ([Measures].[Reseller Sales Amount]
, [Geography].[Geography].[Country].&[Canada]
);
