7 March 2025 For our in-class exercise work this week:

Schema:
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.
