One of the current trends in Business Intelligence is the digital dashboard.
The dashboard on a car tells the driver the current state of the car’s
operations: current speed, current amount of gas in the tank, etc. A digital
dashboard tells a decision maker the current state of the business. You can use
many of the features provided in SQL Server Reporting Services (SSRS) to prepare
your digital dashboard. An interesting new feature in SQL Server 2008 is the
gauge data region, which we will be exploring here.

We shall discuss an example of using the gauge data region for a digital
dashboard. For the example over here I am using the AdventureWorks2008 database,
which can be downloaded from http://www.codeplex.com/. Let’s discuss the various
steps involved.

INNER JOIN
Production.ProductSubcategory ON Production.Product.ProductSubcategoryID =

Production.ProductSubcategory.ProductSubcategoryID INNER JOIN
Production.ProductCategory

Right click on the new data source in the Report Data window and select Add Dataset. The query above lists the sales for a given category name.

ON Production.ProductSubcategory.
ProductCategoryID = Production.ProductCategory.ProductCategoryID

WHERE Production.ProductCategory.Name
