At  the  initiator end,  all  patients register  for  medical care  at  first by
entering all their  particulars in the  database. These particulars  include the
patient name  and address  and contact  number as  well. The  patient enters his
priority based on the  severity of his condition  by means of a  ticket which is
high-h, low-l,  medium-m or  severe-s. Also  the patient  indicates the date and
time that  he wishes  to be  seen and  given medical  attention. The  nurse also
enters all her  particulars including her  contact number and  shift timings. At
the bidding and validation end, we have the following. The current date and time
are already  stored indicated  as ‘cd’  and ‘ct’  respectively. The patient must
make an appointment  ‘pad’ which is  greater than or  equal to the  current date
‘cd’. He must also make an appointment at a time ‘pat’ greater than the  current
time ‘ct’. Only if both the date  and time are correctly entered by the  patient
will it be recognized as a valid request. Validation is necessary for the  nurse
database as well. The nurse details are indicated by N. If an already registered
nurse  attempts  to enter  her  details again  indicated  by C,  it  will return
‘Invalid nurse record’ else it will return ‘Correct nurse record’. Both outcomes
will be  sent to  the result  generator. If  the date  and time  are incorrectly
entered by the  patient it will  return an invalid  message and he  will have to
register again and indicate his  requirements correctly. When the date  and time
are correctly entered by the patient along with his priority, it enters into the
‘service given’ circuit which determines which patient has the highest  priority
and allocates the nurse available and the patient receives the required medical 
attention.
