In this assignment you will implement a simple Healthcare management system in which an administrator of the system can search for all appointments of a particular doctor. Also, the administrator could add a doctor, delete a doctor, add an appointment and delete an appointment record.

First, we want to store data about patient medical records and appointments $($for simplicity assume that each doctor can have many appointments and the appointment is handled by only one doctor$).$

We want to store $5$ doctors and $10$ appointments.

Save the data for doctors and appointments in the following format: delimited fields and length indicator record.

Consider the following specifications for the fields of each record in both the doctors and appointments data files:

$\backslash$table$[[$Doctors Data file$],[$Char Doctor ID $[15]//$primary key$],[$Char Doctor Name $[30]],[$Char Address $[30]]]$

$\backslash$table$[[$Appointments Data file$],[$Char Appointment ID $[15]//$primary key$],[$Char Appointment Date $[30]],[$Char Doctor ID $[15]//$ secondary key$]]$

Please consider building the following indexes:

Primary index using the Doctor ID $($for Doctors data file$).$

Primary index using the Appointment ID $($for Appointments data file$).$

Secondary index using the Doctor ID $($for the Appointments data file$).$

Secondary index using the Doctor Name $($for the Doctors data file$).$

Implement add, update and delete functions. Make sure that consider the following situations in your design:

When you add a record, first look at the AVAIL LIST, then write the record. If there is a record available in the AVAIL LIST, write the record to a record AVAIL LIST points and make appropriate changes on the AVAIL LIST.

If the record to be added already exits, do not write that record to the file.

When you delete a record, do not physically delete the record from file, just put a marker $(*)$ on the file and make appropriate changes on AVAIL LIST.

If the record to be deleted does not exist, display a warning message on the screen.

For the update function, make updates to non$-$key fields only. Also, updates to these fields will not exceed the allocated size.

Note: all add and delete operations will affect indexes.
