The book teaches a means of analysing massive data sets, that is different from SQL, but which can be applied to SQL databases. Called MDX, it lets you, the analyst, define a hyperspace of several dimensions, where the number of dimensions can be greater than 3. Along each axis, there is a discrete set of values. Unlike engineering or physics analysis, where the spaces often take on continuum values. The authors show how MDX comes with a rich set of built in functions. But you can also easily write your own, that use these, or start from scratch. The Analysis Service version 2005 encompasses MDX, along with a user interface. The MDX syntax borrows deliberately in part from SQL, since as a practical matter, many of its users will come from a SQL background. But for analysis, it is often superior, offering a more flexible and intuitive syntax geared towards analysis. One potential 'problem', which is not mentioned, is that if you get used to the MDX syntax, going back to writing code for a strict SQL application might now seem so constricting. Of course, this is scarcely MDX's fault. The book's chapters are often quite short ('bite-sized') and are easy to follow.
