We now have to perform a set of steps that allow us to work with
the Warehouse cube in its currently partitioned state. As I
mentioned earlier, we might have merged the partitions, or "started out
fresh" otherwise, but taking the following steps to re-align the new views
to the partitions represented a quick approach to preparing to work within the Warehouse
cube structure, while minimizing rework.
In addition to handling the aforementioned eccentricities, we also
get practice at a couple of things that might be useful to us in a real world
scenario. Keep in mind that this "re-alignment" step for the
partitions will not likely be a common requirement in most scenarios, as I
stated earlier, as final partitioning, if enacted, would likely come
after major cube design work was done. Even if partitioning was in place, we
would likely merge to a single source, make our design changes, and then
re-partition based upon the new design (which might change the overall
partitioning strategy anyway).
9. Expand the Warehouse
cube within the Relative Time Sample database, by clicking the "+"
to its immediate left.
10. Expand the Partitions
folder that appears immediately underneath the expanded cube.
11. Right-click the Warehouse
(the uppermost) partition.
12. Select Edit from
the context menu that appears, as depicted in Illustration 32.
