problem: For the given problem statement:
The blood bank wants to computerize its operations. The bank issues blood to patients and hospitals. If a hospital requests for blood the request is instantly serviced.

The blood bank as well collects blood from non-blacklisted donors. This collection can be from regular donors or from camps that are organized now and then. Every time blood is to be collected, the bank checks whether the person is suffering from some fatal or non-fatal disease or not. In case the person is recognized to have fatal disease, the person is black-listed. If the person is healthy, then the blood group is determined and the blood is collected and stored in bank. Collection report is produced by the blood bank and given to the donor.
