Analysis Services Introduction. Creating OLAP cube
This article show you, how to create data warehouse: database, dimensions, measures and OLAP
cube.

1. Creating a Database
1. Create car_transactions database. Open SQL Server Management Studio and execute the
command
CREATE DATABASE car_transactions;

2. Swich to car_transacion database and create a few table

3. Create a user
1. Open SQL Server Management Studio.
2. In Object Explorer, right-click the Logins folder and select New Login.
3. Type login name.

5. 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.

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

Next.
4. Select dimensions and facts tables and then click Add Related Tables and Click Next. Accept
the default name and click Finish.
5. The Data Source View designer appears, displaying the tables you selected

7. Creating dimesnions
Creating a customer dimension
1. In Solution Explorer, right-click the Dimensions folder and select New Dimension.
2. On the Welcome to the Dimension Wizard page, click Next.
3. Verify that Use An Existing Table is selected and click Next.
4. Select Customers from the Main Table list.

9. Drag the Country attribute from the Attributes pane and drop to Hierarchies pane.
10. 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. Visit:

8. Creating a cube
1. In Solution Explorer, right-click the Cubes folder and select New Cube.
2. On the Welcome To The Cube Wizard page, click Next.
3. Verify that Use Existing Tables is selected and click Next.
4. In the Measure Group Tables list, select the Transactions_facts_table and click Next.
5. The Select Measures page lists the measure groups and measures that the wizard will create.
Click Next.
6. On the Select Existing Dimensions page, verify that the Customers, Cars and Salesmen
dimensions are selected. Click Next.
