$(2)$ Consider the conceptual schema about a hotel chain given below and the list of extensions

about customers to the database domain. Modify the conceptual schema to make it consistent

with the required extensions. Note that, only one $($the final with all the extensions$)$ conceptual

schema is expected.

We would like to extend the database domain in the following ways.

$($a$)$ A description of a customer consists of the first name, last

name, date of birth and optional nationality.

$($b$)$ The first name, last name and date of birth together identify a

customer.

$($c$)$ Customers book hotels.

$($d$)$ A booking is described by booking date, room type, expected

arrival date, the total number of days a booking is valid for and

the rate.

$($e$)$ A customer can only book a hotel once a day.
