Query: What about Excel for Mac 2011 users

The Author assumes you have drivers for various database sources such as MS SQL, MS OLAP, dBase, Oracle, Paradox etc as part of your default Excel installation.I am using Excel for Mac 2011 which does not come with these drivers in the default installation, so you cannot follow the book's examples or use the online files without coughing up for extra drivers from 3rd party suppliers.The Author is not responsible for shortcomings in Excel for Mac 2011 (vs Excel on other platforms) but he should be aware of them, acknowledge them and give advice on the best way to overcome them.
