SunQuest ETL and Cube Build

1. Sunquest Business Intelligence Process Flow

Sunquest Data is the source from which the data is transformed through SSIS into the

SunquestMart .

From the SunquestMart through SSAS we are Building the Cube.

The SQCube which is Build is accessed by End-users through Excel.

2. Source For Sunquest ETL The table SQCubeLoad is the source from where the data is fetched by ETL.

3. Dimensions in SunQuest ETL Sunquest ETL starts from Building the Following Dimensions.

1. Dimorderables

2. DimPhysician

3. DimSite

4. DimLab

5. DimResultStatus

6. DimCompany

7. DimTech

4. Updating the DimOrderables and DimSites using Exclusion List

The Task Update Dimsites and Orderables will Exclude the Sites and OrderCodes as per the

Exclusion data in the Mart

5. Fact Build Fact table is a Truncate Load and there is SQL Task Which Truncates Fact Table Every time whenever

ETL Runs

6. Finding out Exceptions and Redirecting them to a Separate table

in the Mart If there are any missing Values for arecord then those record will go to the

FactOrdersException.

7. Dimension Build This task builds all the Dimensions.

8. Cube Build This Task builds the cube.

9. SSAS Overview Name of the Cube Built:SQCube

Dimensions used in the SQCube are as given Below

Logical Diagram of the SQCube is as given below with Orders as a Fact table and rest of them as

dimension tables.
