Create a database structure that holds information for a doctors office. The doctor wants to store demographic information about patients (address, age, gender, marital status), medications dispensed (when, what, quantity), and billing information (amount billed, amount and date paid, insurance information). You do not have to create the database. Sketch out the structure as follows: There should be three tables and each record should have at least four fields. You must include the information given in this problem but you can add other information you feel is significant. Save this file as either an HTML page named doctors. html or a text file named doctors.txt.
