| Primary Inventory Group Overview |
 Example 1 The Primary Inventory Group is the defacto central driving point of the entire website. All other functions are dependent upon it, and it is in fact the basis of the Navigation Bar found on the left hand side of any web page (example 1). |
 Example 2 The makeup of the website is top-to-bottom hierarchical in structure. That is, there can be an unlimited number of Primary Inventory Group items, under which there can be an unlimited number of Secondary Inventerory Group items, under which there can be an unlimited number of Inventory Items - these are the things being sold (example 2). |
