Create the PivotTable
View
Now that we have put a
query in place to act as a data source, we are ready to set about the creation
of a sample report. In our present case, we will create a straightforward PivotTable
view to act as our report, keeping in mind, as we noted before, that any
number of more elegant, robust, and enterprise-oriented solutions might be more
appropriate in your own production environment.
Remaining
within the Queries section of the Database window, let's take the
following steps to begin construction of our new PivotTable view.
1.
Single-click
the new Warehouse Cube Activity to select it
2.
Click Open
on the Database window toolbar.
The
query results set appears within the main window, as shown in Illustration 14.
3.
Select View
--> PivotTable View from the
main menu, as shown in Illustration 15.

After a few seconds, a blank PivotTable appears, with a
floating PivotTable Field List appearing in the foreground, as shown in Illustration
16. Note the appearance of the two additional fields that are based upon
the StartTime field.

As I suggested
in the DatabaseJournal article Create
a PivotTable View in Access, the blank PivotTable offers an excellent "conceptual"
view of the basic makeup of a PivotTable. With a PivotTable we can create views
of our data that strongly resemble, but far out-power, a cross-tab query. The
PivotTable allows us to define the data values that we wish to occupy multiple
rows, columns, pages (or "layers") and summaries.
We can see above that the center of the table contains
numeric data ("measures"), while the rows and columns present (often
hierarchical) dimensional data. We will see a simple illustration of how these
areas of the conceptual "map" can be populated with our cube usage
analysis data in the steps that follow.
Let's define our view to
effectively present the data set returned from our new query.

If the PivotTable
Field List does not appear, initialize it clicking the Field List
button, shown in Illustration 17, on the toolbar.

In the Field
List, click MSOLAP_Cube to highlight it.
6.
Select Filter
Area in the selector box, to the right of the Add to button (at the
bottom of the Field List), as shown in Illustration 18.
