On the download page for DataAssist, there is the "Solution Recipes: Support Files" in this section is the "SiteAssist and DataAssist: Solution Recipe Files" which contains a DataSource folder with the blueSkyMusic database that can be used while following the getting started guide.
The idea of the getting started guide is to walk through using the DataAssist wizard to *create* the DataAssist pages. Other than the Database, you do not need any additional pages to follow the DataAssist getting started guide.
