Draw the Context Level and DFD Level 1 Diagram for the case-study below. The Blood Bank Testing Unit. This is one unit within the College Street Red Cross Blood Donor Centre.On the day following a blood donation, the Blood Bank unit tests all blood for blood type and potentialviral agents. They send the results of these tests to the Processing Office (another unit of the Centre). Foreach tested blood unit, they fill out a form which lists the blood unit number, the blood type, the date andthe results of the test.

These are discarded and the list sent back to the Processing Office with a signedindication of the disposal of the units.The Blood Bank also distributes blood to various hospitals requesting blood. Requests usually come in forspecific blood types. The Blood Bank prepares refrigerated containers of these units and distributes themto the hospital vans when they arrive to pick up their supply.

When the order is filled, the lab technician signs the order and returns a copy to theProcessing Office. A copy of it travels with the blood to the requesting hospital.

Coral Help Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: The 90 is primary, going east/west. Ex: If the input is: 290 the output is: The 290 is auxiliary, serving the 90, going east/west. Ex: If the input is: 0 or any number not between 1 and 999, the output is: 0 is not a valid interstate highway number.
