Creating a Data Source The first task in creating an Analysis Services project is to create a data source. The data source contains the information that Analysis Services uses to connect to the source database. It contains the data provider name, the server and database name, and the authentication credentials that Analysis Services will use. 1. In BIDS in Solution Explorer, right-click the Data Sources folder and select New Data Source. The Data Source Wizard appears. 2. On the Welcome page, click Next. 3. On the Select How To Define The Connection page, click the New button. The Connection Manager dialog box appears. 4. Type a server name: localhost. 5. In the Select Or Enter A Database Name list box, select car_transactions 6. Click Test Connection. A dialog box opens with the message “Test connection succeeded.” Click OK. 7. Click OK to close the Connection Manager dialog box. 8. In the Data Source Wizard, on the Select How To Define The Connection page, click Next. 9. On the Impersonation Information page, select Use The Service Account and click Next. 10. Click Finish to complete the wizard. Now that you have created a data source, you are ready to create a data source view. Watch, how to create a Data Source. Visit: http://www.learn-with-video-tutorials.com/analysis-services-video-tutorial-free 6. Creating a Data Source View A data source view is a logical data model that exists between your physical source database and Analysis Services dimensions and cubes. When you create a data source view, you designate the tables and views in the source database that contain data that you want to use to build dimensions and cubes. 1. In Solution Explorer, right-click the Data Source Views folder and select New Data Source View. The Data Source View Wizard appears. 2. On the Welcome page, click Next. 3. On the Select a Data Source page, select the car_transactions relational data source and click Lear more, visit: http://www.learn-with-video-tutorials.com

Drag the City and Cust ID attribute from the Attributes pane and drop it on <new level>. 11. In the Hierarchies pane, right-click the new hierarchy header and select Rename. Type Country Customers Hierarchy and press Enter. 12. In Object Explorer, right-click the Customers dimension, and select Process. Then click Yes. 13. In the Process Dimension dialog box, click Run. 14. In the Process Progress dialog box, click Close. Now that the Customers dimension has been builded. 15. You can preview the dimension - click Browser tab. Create another dimension: salsmen, cars and time. Watch, how to create all dimensions.
