Question

EspressoCoffee is considering permitting vendors to access certain parts of its vendor module, such as verifying orders placed and tracking items received by EspressoCoffee. This would represent significant time and cost savings to EspressoCoffee since its employees would not use time checking this information for vendors. The vendors would be able to access the information themselves.
In order to permit vendors to access EspressoCoffee’s system, the vendor would need to be authenticated by logging on with a specified user ID and password. EspressoCoffee would then verify the vendor and provide the vendor with access to the appropriate areas of EspressoCoffee’s database.
Describe how the DFDs would need to be modified if this change were made to EspressoCoffee’s system.
