What is SSAS Cube

• The Multi-Dimensional Data Model consists of:

a data cube, which is a multi-dimensional data structure consisting of dimensions (which contain members) and measures; within a dimension, members may be in a hierarchical relationship

• A set of operations to query cells of the cube using dimension members as coordinates

• Rules that dictate how measure values are rolled up (or aggregated) within hierarchies or how certain cells are computed in a sparse cube

Way to access Cube

6

•Business Intelligence Development Studio (BIDS): BIDS is used to access the cube and preview the data at the design time. This option is useful only for the developer community and is not applicable to business analysts and decision makers. BIDS was replaced by the SQL Server Data Tools in SQL Server 2012, but has much of the same functionality.

•SQL Server Management Studio (SSMS): SSMS is used to access the cube by people in different roles. It is used to access the cube by the development/testing teams to validate the data. Those business analysts and decision makers (very few) who are familiar with SSMS; also use it for accessing the cubes.

•Microsoft Office Excel: Excel being one of the most widely used data analysis tool, has the capability to connect to cubes and perform different kinds of reporting such as pivot tables, charts, etc. It is used by many decision makers, business analysis, and even developers for reporting purposes.

•SQL Server Reporting Services (SSRS): SSRS allows Analysis Services databases or cubes as a data source to build reports. This option is available both in BIDS\SQL Server Data Tools while building canned reports and in Report Builder while doing ad-hoc reporting.

•PerformancePoint Services (PPS): PPS which is now a part of SharePoint 2010 allows building KPIs, scorecards, reports, and dashboards with Analysis Services cubes as data source.

Comparison of Queries Written in T-SQL & MDX - Construct

--TSQL Count Select Count(1) from vwDimCompositeQuestionAssoc

--MDX CountSELECT NON EMPTY{[Measures].[Vw Dim Composite Question Assoc Count]} ON COLUMNSFROM [QHPAnalysis]

Now lets Convert Complex TSQL in to MDX

Select que.QuestionText,fct.TopBoxCountfrom FctQuestionSurvey fctinner join DimQuestionSample queon que.QuestionID=fct.QuestionIDWhere Fct.SurveyID=80101878 and que.QuestionText='In the last 6 months, did you get information or help from your health plan''scustomer service?'

--Syntax for Join and Where Condition in MDX

SELECTNON EMPTY

ON COLUMNS,NON EMPTY

{--Row Selection

}ON ROWS

FROM(

SELECT{--Where Condition Column Selection

} ON COLUMNSFROM(

SELECT{--Where Condition Row Selection

} ON COLUMNSFROM[Cube Name ]

))WHERE

--Where Condition on Row Selection

Syntax for Join and Where Condition in MDX

SELECT

NON EMPTY

ON COLUMNS

,

NON EMPTY

{[Dim Question Sample].[Question Text].[Question Text].ALLMEMBERS }

ON ROWS

FROM

(

SELECT

{

[Dim Question Sample].[Question Text].&[In the last 6 months, did you get information or help from your

health plan's customer service?]

} ON COLUMNS
