How do I create a database with two tables?
The first table is a list of names and addresses, with columns for: first name, last name, street address line 1, street address line 2, suburb, state, postcode and country, where all those columns are strings, and also columns for latitude and longitude, where those two columns are numbers (decimal degrees, not degrees-minutes-seconds).
The second table is a list of suburbs, with columns for: suburb name, state and postcode (all strings) and latitude and longitude (numeric).
