Just need to find out what database fields they fill now.

The joy of having a relational database is that there isn't necessarily a simple link between tags and fields. Kodi processes the tag data, not just copy it. Initial artist and album data is derrived from the song tag data, so you could say one tag goes in many places, data is normalised, so many tag values go in one place. There is processing, for example to decide if an album is a compilation it uses
1) album name is non-empty AND
2a. the songs have different artists OR
2b. all tracks are marked as part of compilation AND
3a. a unique primary artist is specified as "various" or "various artists" OR
3b. we have at least two primary artists and no album artist specified.

So can we not try to put database field names next to tags, it isn't going to help anyone.

Thanks, I've removed the database tables for now from the wiki article.
