Two of the data flows generated by the first process, Receive and Transform Customer Food Order,

go to external entities, so we no longer have to worry about them. We are not concerned about

what happens outside our system. Let's trace the flow of the data represented in the other two

data flows. First, the data labeled Goods Sold go to Process $2\mathrm{.}0,$ Update Goods Sold File. The

output for this process is labeled Formatted Goods Sold Data. This output updates a data store

labeled Goods Sold File. If the customer order was for two cheeseburgers, one order of fries, and

a large soft drink, each of these categories of goods sold in the data store would be incremented

appropriately. The Daily Goods Sold Amounts are then used as input to Process $4\mathrm{.}0,$ Produce

Management Reports. Similarly, the remaining data flow generated by Process $1\mathrm{.}0,$ Inventory

Data, serves as input for Process $3\mathrm{.}0,$ Update Inventory File. This process updates the Inventory

File data store, based on the inventory that would have been used to create the customer order.

For example, an order of two cheeseburgers would mean that Hoosier Burger now has two fewer

hamburger patties, two fewer burger buns, and four fewer slices of American cheese. The Daily

Inventory Depletion Amounts are then used as input to Process $4\mathrm{.}0.$ The data flow leaving Process

$4\mathrm{.}0,$ Management Reports, goes to the sink Restaurant Manager. DFD
