Creating a New Cube
The folder structure for the project developed in Part 1 is shown in the next figure. The Northwind.ds data source and the Northwind.dsv data source view were configured in Part 1. There are no pre-existing cubes in Nwind2008.
Right click the Cubes folder and from the drop-down menu you can create a new Cube.
Click on New Cube... menu item. This opens the Cube Wizard welcome window as shown.
Click on the Next button. This opens the Select Creation Method page of the wizard as shown. There are three options and the default is used for this article.
Click on the Next button. This opens the Select Measure Groups tables. At least one table must be chosen to continue. There is even the option of asking for a suggestion.
Click on the Suggest button at the top. The program goes through the motions and comes up with two tables as candidates for Measures group, the Products table and the Order Details table. You will see check marks appearing for these two tables. Accept the suggested tables for measures and click on the Next button.
This opens the Select Measures window where you can choose measures that you want to include in the Cube as shown.
Uncheck the ID related items in the Products table and click on the Next button. This brings up the Select New Dimensions window as shown in the next figure. Here also one could choose the needed items. For this article the default is accepted.
Click on the Next button. This takes you to the Completing the Wizard window which shows your Cube contents in a tree view as shown.
Now click on the Finish button. This creates the Cube as shown in the Solution Explorer.
Now you will see additional tabs open up for the Northwind.cube as shown. Using these tabs you can look at more details. These are outside the scope of this article.
Also separate windows gets displayed for Cube's Measures and Dimensions as shown.
Also, the Data Source View of the Cube with the relationships between the Dimensions and Measures gets displayed as shown.
At this point it may be interesting to know how all this might have affected the Analysis Server. As you can see from the following figure that every node is empty. The database is there because we created an empty database with the same name to start with.
Right click the Northwind.cube and from the drop-down menu choose Process... as shown in the next figure.
Since a database was pre-existing you may get the following message from the Microsoft Visual Studio interface.
As the answer for the question posed, click on the Yes button. The Visual Studio begins the deployment and after a while you should see the Deployment Succeed message as shown.
Now if you go back to the SQL Server Management Studio and refresh the NWind2008 database you should be seeing the database details as shown.
As soon as the deployment is completed the Visual Studio Interface displays the Process Cube Wizard window as shown. Although one can make many changes as one might see from the window, for this article, the defaults are accepted. Since this is the first time working with the Cube, the Process Option, namely Process Full is appropriate. Later it is possible to use other options shown by the pull-down menu.
Click on the button Run.... The Cube gets processed so that all the SQL queries that form the basis for setting up the Cube gets executed. The Process Progress window shows the details of the processing. You may reprocess if changes are made to the Cube.
Click the View Details button to see the following display.
Close the Process Progress and Process Cube windows.
This article shows the design and processing of the Cube using the Data Source and Data Source View designed in Part 1. The Visual Studio interface provides a very straight forward procedure to process the Cube and the process is unambiguous. The processing of the Cube essentially consists of deploying the database and then processing the various queries necessary for the details contained in the Cube.
