Using the Dimension Designer

The dimension designer, like the cube designer, has tabs across the top and a three-pane view in the rest of the window. Within the Dimension Structure tab, the Attributes pane is on the left, the Hierarchies And Levels pane is in the center, and the Data Source View pane is on the right.

Attributes can be displayed in a tree, grid, or list view. Cycle through the views by choosing the Show Attributes In option from the Dimension menu or the Show Attributes In option from the Attributes pane’s shortcut menus. You can also use the third drop-down button from the left on the Dimension designer’s toolbar. Note that when you enter the list or grid views, the Hierarchies And Levels pane pivots from the center to the upper left and the Attributes pane shifts to the lower left. Certain properties for attributes are available in the grid view, but all properties are accessible through the Properties window regardless of which view you’re in. We’ll discuss more on the Properties window later.

Attributes can also be renamed via their shortcut menus, the Name property in the Properties window, or by pressing the F2 key when the attribute is selected. Rename the Vw Geography attribute to Postal Code now. The attribute is in fact based on the Postal Code field, but its default name was set otherwise because it is the key attribute for the Geography dimension (which is based on the view Vw Geography). Renaming the attribute now will make things much more user-friendly when it comes time to query the cube.

The dimension designer makes it easy to create hierarchies from the universe of a dimension’s attributes. Let’s create a hierarchy for the Geography dimension now so that we can later query our cube data hierarchically by country, then state or province, then city, and then postal code. Start by dragging the Country attribute from the Attributes pane to the Hierarchies And Levels pane (you may also right-click the Country attribute and select the Start New Hierarchy option from its shortcut menu, or left-click the Country attribute and select the Dimension/Start New Hierarchy option from the main menu). This will create a new hierarchy with the default name of “Hierarchy” in its own rectangular block, with the Country attribute as the hierarchy’s top (and only) level.

You can drag additional attributes onto this block to create additional levels (or select the hierarchy and then either right-click an attribute and select Create Level from the shortcut menu or left-click an attribute and select the Create Level option from the Dimension menu). You can reorder the levels within the hierarchy by using drag-and-drop, and you can delete and rename attributes and hierarchies in a manner similar to other UI scenarios already described. Also, instead of dragging attributes from the Attributes pane to create hierarchies or add levels to an existing hierarchy, you can drag columns from the Data Source View pane.

Using any of the techniques just discussed, add the State, City, and Postal Code attributes as the second, third, and fourth levels of the new hierarchy (leaving Country as the first level). Once you’ve added all the levels, rename the second level from State to State-Province and rename the hierarchy itself to Country - State-Province - City - Postal Code. The completed hierarchy design is shown in Figure 14.

The dimension designer has two other tabs: Translations and Browser. You can use the Browser tab to examine all of the dimension’s levels and each level’s members in a tree view, but only after the cube has been processed (a step we’ll take you through shortly).

Working with the Properties Window and Solution Explorer

Some of the settings we’ve discussed, can be set through the Properties window. To see how this works, return to the cube designer’s Cube Structure tab, click on any measure in the Measures pane, and then look at the Properties window. (Press F4 or choose the View/Properties Window main menu option if it’s not visible.) To make the Properties window easier to view, assuming it is docked, double-click its caption bar to undock it (you can double-click its caption bar again to redock it), center it within your screen, and resize it so its columns are wide and many rows are displayed without the need to scroll. Your Properties window should now look similar to Figure 15.

Figure 13. The Properties window allows advanced manipulation of measures, dimensions, cubes, and other objects.

Notice how AggregateFunction and DataType are visible and editable, as are several other properties. Click the drop-down arrow in the upper-right corner of the Properties window, and you should see all the measures in your cube displayed in the drop-down list. Double-click the Properties window’s caption bar again to dock it, and then select a dimension in the Dimensions pane. Undock the Properties window a second time, and you’ll see that this dimension’s properties are now editable and that all dimensions in your cube are listed in the drop-down list at the top of the window. This technique works for virtually any class of object in your cube, in any pane, in any tab of the cube designer (except the Calculations and Browser tabs) or dimension designer. Experiment with this technique in different parts of the designers so that you can appreciate the breadth of power the Properties window has in the cube editing process.

Before we move on to processing and querying our cube, you should know that you can manipulate high-level objects such as data sources, data source views, dimensions, and the cube itself by opening them from Solution Explorer. For example, to edit a dimension in the dimension designer, instead of clicking its hyperlink in the Dimensions pane of the cube designer, you can double-click its node in the Dimensions folder of your project in the Solution Explorer window. Try this to see how easily it works. Also, if you right-click any editable object in the Solution Explorer window and choose View Code, you’ll see that the basis for each object is a simple XML file. Imagine the cube design/generation possibilities this raises for third-party and custom-developed front ends.

Processing the Cube

You can process your dimension in the dimension designer by using the second toolbar button from the left or by choosing the Dimension/Process... option from the main menu, but for now just close the dimension designer and click Save when prompted. Back in the cube designer, you can process the entire cube by using the Database/Process... or Cube/Process... option, or by clicking the Process toolbar button (second from left). Processing the cube or database automatically processes any pending changes to dimensions they may contain.

Processing your cube requires that your Analysis Services project be built and deployed. When you choose to process your cube (do this now), if it hasn’t already been built and deployed (which ours has not), you’ll be notified that these steps are necessary and asked if you’d like them to be performed before building. Click Yes. (Alternatively, you could first execute the build and deploy operations from the Build branch of the main menu.)

You can watch the progress of the build and deploy processes in the Deployment Progress window. Once these steps are complete, you’ll be prompted with the Process Cube - <cubename> dialog box. The Remove, Impact Analysis..., and Change Settings... buttons in this dialog box provide precise control over how your cube is processed.
