Use the following narrative to answer the accompanying questions.
iBacci Chocolate sells fine European chocolates and candies. The company buys from local Italian artisans and sells the items online. The company’s ITEM database table used to account for inventory is automatically checked at a specific time of the day to determine if the quantity has dropped below the reorder point. If so, the system automatically processes a purchase order and forwards it to the appropriate employee. The employee reviews it and authorizes the PO. The PO is finalized and sent to the specified vendor.
1. Annotate the narrative, labeling and numbering the events.
2. Create an event-agent-database (EAD) table. (Hint: When a system is automated in this way, the agent on the DFD, instead of being labeled as a person, is labeled schedule to designate it is a scheduled activity.)
3. Build a level-0 DFD for create purchase orders.
