Using the Dimension Wizard

To invoke the Dimension Wizard and create a dimension (which we’ll need to do because we haven’t yet created our time dimension), choose the Cube/Add Cube Dimension... option, select the Add Cube Dimension... option from the Dimension pane’s shortcut menus, or click the Add Cube Dimension toolbar button (sixth from left). Each of these actions brings up the Add Cube Dimension dialog box, shown in Figure 9.

Figure 9. The Add Cube Dimension dialog box allows you to add existing database-level dimensions to your cube or define new dimensions.

Click the New Dimension ... button to bring up the Dimension Wizard. You can also invoke the Dimension Wizard by right-clicking the Dimensions folder in the Solution Explorer window and choosing New Dimension. Invoking the Dimension Wizard using this technique adds the dimension to the Analysis Services database but not to the cube; to add the dimension to the cube itself, you must use the Add Cube Dimension dialog box and select your new dimension from the list of dimensions in the database.

On the Welcome page of the Dimension Wizard, click Next. On the Select Data Source View page, confirm that the Northwind data source view is selected and click Next again. On the Select The Dimension Type page, you can indicate whether you are creating a standard dimension (the default), a time dimension, or a server time dimension. In our case, we’ll select the Time Dimension option.

For a standard dimension, you would need merely to accept the default option button selection and click Next. (Go ahead and try these next steps if you’d like, but when you’re done, use the Back button to come back to the Select The Dimension Type page and select Time dimension again.)

On the Select The Main Dimension Table page, you can select the desired dimension table (from the top combo box) and its key column(s) (from the checked list box that takes up most of the page). You can also optionally select a name column (from the bottom combo box). Click Next to go to the Select Dimension Attributes page, where you can specify the name, key column, and name column of each of the dimension’s attributes. Several attributes are suggested automatically, based on the columns in the table, and you can edit or deselect any of these.

Click Next to go to the Specify Dimension Type page. If you’re experimenting with standard dimensions, you can stick with the Regular dimension type and click Next to go to the Define Parent-Child Relationship page. You can click Next to advance to the Detecting Hierarchies page. On this page, the wizard will attempt to detect, from the structure of your dimension table, possible hierarchies in your dimension. You should wait for the processing to complete and then click Next. On the Review New Hierarchies page, you can review the hierarchies, if any, generated by the wizard, deselect any of them (or any of their constituent levels) if you’d like, and then click Next.

If you followed the previous steps, click the Back button to get back to the Select The Dimension Type page (not the Specify Dimension Type page), and select the Time Dimension option button. If you didn’t follow the previous steps, this should already be done. In the Time Dimension combo box, select tblTime (it will appear as dbo_tblTime) as the table that will serve as our time dimension table. Time dimension tables are specially configured to contain a key (which also appears as a foreign key in the fact table) and columns with corresponding year, month, or other time-related data. Figure 10 shows the structure and an abbreviated set of data for tblTime. (The four non-key columns in that table will each support a level in the time dimension.)

Click Next to proceed to the Define Time Periods page, where you should select the columns in the Time Table Columns column that correspond to the items in the Time Property Name column. (See Figure 11 for the proper settings for tblTime.) The Time Intelligence feature in SQL Server 2005 Analysis Services allows this type of declarative identification of dimensional levels. Click Next to continue. On the Review New Hierarchies page, review and confirm the time hierarchy that the Dimension Wizard constructed for you, and then click Next again.

Figure 11. The Define Time Periods page allows you to tell the Dimension Wizard which columns represent which levels in the time dimension.

On the Completing The Wizard page, you can review the schema for your dimension, accept its default name or enter a name of your own (for our example, type Time as the dimension name), and then click Finish. Back in the Add Cube Dimension dialog box, make sure that the new Time dimension is selected, and then click OK to add it to the cube and return to the cube designer. Your new dimension should be displayed on the Dimensions pane of the Cube Structure tab, and the dimension table should be added to the Data Source View pane.

For the new time dimension, or any of the others on the Hierarchies tab or the Attributes tab, you can drill down and display child nodes. The first child node in either pane is a clickable hyperlink that opens the dimension designer and allows you to edit that dimension. (The nodes that follow enumerate the attributes or hierarchies and levels of the dimension, if any, depending on which tab you’re on.) In addition to the hyperlink, you may open the dimension designer by selecting a dimension in the Dimensions pane and choosing the Edit Dimension option from the Cube menu, or you may right-click the Dimension and select the Edit Dimension option from its shortcut menu. Use one of these techniques to open the Geography dimension in the dimension designer now.
