The document provides SQL commands to create three database tables: a salespeople table with fields for salesperson number, name, and city; an orders table with fields for order number, date, salesperson number, and amount; and a customers table with fields for customer number, name, city, rating, and salesperson number. Sample data is inserted into each table.

insert into commission_order_Ravi values(302,'15-Aug-2013',2,3000);
insert into commission_order_Ravi values(303,'25-Aug-2013',3,4000);

insert into customer_Ravi values(06,'Shashi','Dibrugarh',176,2)
insert into customer_Ravi values(10,'Gyan','Pune',120,3)
