Procedure

We now have a clone cube with which we can pursue our examination of CROSSJOIN() optimization. Let’s initialize the MDX Sample Application, as a platform from which to perform our practice exercises, taking the following steps:

1. Start the MDX Sample Application.

We are initially greeted by the Connect dialog, depicted in Figure 7.
