1 March 2024 From our in-class exercise work this week:

Earthquake (qname, qdate, latitude, longitude, magnitude, fault)
Damage(cityID, qname, cost, liveslost)
Cities(cID, cname, latitude, longitude, population) [city names may not be unique]
Questions (in SQL, and relational algebra where possible):
  1. Find the names and dates of earthquakes whose magnitude was greater than 7.0.
  2. Find the average population of all the cities whose names start with "San".
  3. List the lives lost, quake names and city names for all quakes that occurred before 1960.
  4. List the city identifiers and total cost, per city, of all quakes with magnitude greater than 7.0.
  5. List the average magnitude of quakes for each fault (grouped by fault).
  6. List all earthquakes and, where applicable, also list city IDs and lives lost in that city for quakes that affected cities.
  7. List the names of cities whose populations are greater than the average city population.
16 Feb 2024 Sample tables for classroom exercises:
CREATE TABLE Books(title char(40), lastname CHAR(40), firstname CHAR(40), pubyear INTEGER, bookID INTEGER PRIMARY KEY)
CREATE TABLE AwardWinners (bookID INTEGER, year INTEGER, award CHAR(60), authorage INTEGER, PRIMARY KEY (bookID, award, year))
CREATE TABLE Awards (awardname char(60), primary key (awardname))
(Note that, to fit on a PPT slide, foreign key key declarations were left out)
