Chapter 2 i dentified the elements of Market Basket Analysis, which
included the Itemset, Objects, and Aἀ nity. In that discussion, these ele-

value-adding Market Basket Analysis application. For that reason, if you
skipped past the irst chapters of this topic to go directly to the solution
design, please go back and read Chapter 2. The information provided
in Chapter 2 will not be repeated here in Chapter 5; the information in
Chapter 2 will be assumed to be a shared common understanding of the
elements of Market Basket Analysis. So, if you have not read Chapter 2,
please stop here and read Chapter 2 b efore continuing with Chapter 5.
Also, you will eventually need the information in Chapter 3 and Chapter
4 as you build a working Market Basket Analysis application. So, please
keep a bookmark in those chapters. Later on when you start to ponder
such questions as “What is my goal? What am I trying to achieve?” and
“Why do the results of my analysis not come out quite right?” that's when
you're ready for Chapters 3 and 4. If, however, you did read all the prior
chapters, get ready to have some fun with Market Basket Analysis.
