Reading the Data Model Primary key: a unique identifier used to retrieve the record One Many manages has

Enrolling a new customer manages has Bruce Wayne, Gotham, NY

The SQL Insert into Customer (c_id, f_name, l_name, city, state) values (7759, 'Bruce', 'Wayne', 'Gotham', 'NY')

Selling insurance to a customer manages has Bruce Wayne, Gotham, NY C_id = 7759

The SQL Insert into insurance_plan (c_id, coverage, premimum) values (7759, , 500)

The previous queries implement operational transactions  Directly related to business operations  Single customer, single contract, deal, service…  “Real time”  Often INSERTs  “Small” amount of data  Large numbers of fast, “simple” queries

Finding our IP exposure by state manages has

The SQL select customer.state, sum(coverage) from customer, insurance_plan where customer.c_id = insurance_plan.c_id group by customer.state

Finding our top three customers manages has

The SQL select top 3 customer.c_id, customer.l_name, sum(loan.principal) from customer, customer_in_loan, loan where customer.c_id = customer_in_loan.c_id and customer_in_loan.l_id = loan.l_id group by customer.c_id, customer.l_name order by sum(loan.principal) desc
