The following tables form part of a database held in a relational DBMS:-

Hotel (hotelNo, hotelName, city)

Room (roomNo, hotelNo, type, price)

Booking (hotelNo, guestNo, dateFrom, dateTo, roomNo)

Guest (guestNo, guestName, guestAddress)

where Hotel contains hotel details and hotelNo is the primary key;

Room contains room details for each hotel and (roomNo, hotelNo) forms the primary key;

Booking contains details of the bookings and (hotelNo, guestNo, dateFrom) forms the primary key;

and Guest contains guest details and guestNo is the primary key.

4.8 Identify the foreign keys in this schema. Explain how the entity and referential integrity rules apply to these relations.

4.9 Produce some sample tables for these relations that observe the relational integrity rules. Suggest some general constraints that would be appropriate for this schema.

Note: When you populate the tables, you need to simulate the real life data. Each table contains at least 10 entries.
