We have just updated, and published, our sample data set, HappyCars, which is useful for learning Data Mining. It has been specially formulated to help you study various data mining algorithms. This data set comes with SQL Server 2012 data tables and views, as well as a SQL Server Data Tools project, containing several data mining structures, and mining models. This set is designed as bonus material, to be used while practicing many of the demos shown in our data mining videos.
HappyCars is available to Full Access Members, and it can be found here.
