I see that release_country and release_unknown_country give the release event information. But there’s no country table. There’s a country_area table, but it only has a single field, which is area. Is that simply to join to the area table and get only countries, and the country field in release_country is actually the id from area?
Also… I see that you have a css file with all the country flags in it that you use to display the flag next to the name of the country. But where do you pull the country abbreviation from? I don’t see that in any of the tables.
