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) • 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; • Guest contains guest details and guestNo is the primary key. Download and install PostgreSQL (Version 14.5). Create the tables for the four rela- tions using the integrity enhancement features of SQL (using the “CREATE TABLE” state- ments) and populate at least 5 tuples for each relation (using the “INSERT” statements) in PostgreSQL. Please report the screenshots of these SQL statements generated from PostgreSQL. Run the SQL statements for the following queries and report the screenshots of these SQL statements and the results generated from PostgreSQL. (a) List the roomNo, type, and price of the Biltmore Hotel (using subquery) (or a specific hotel name in your database). (b) What is the average price of a room? (c) List the guestNo and gusetName of guests who live in Chicago or Seattle, alphabetically ordered by their names. (d) List the number of rooms in each hotel in Kansas City. (e) List full details of every room in Room relation. (f) Update the price of all rooms by 8% and then list full details of every room in Room relation. Compare the output with the output in (e).
