Why are two variables (# of ITEMS and # of emulated browsers) used to determine the scaling of the database tables?
Unlike a physical store where the size of the inventory determines the physical space allocated, which in turn determines the number of customers it can cater to, the store on the web has to deal with the 2 issues independently. Thus, the 2 variables are used, where # of Items controls the size of the inventory and the # of Emulated Browsers controls the size of the supported customer population.
