@matigo Maybe I missed out some detail. Basically, I don't have any sort of server ATM, Dropbox aside — but you can't run MySQL off of Dropbox, only sync the data file.
What I want ideally is to have a database on Dropbox — or some other location that all my devices can access — that I can use to store all my tasting notes. In a perfect situation, I would have a form like below:
winekey
> date
> type
> winery
> region
> year
> name
> grape1
> grape2
> grape3
> ---
> winekey
> winenoteskey
> smell
> taste
> rating
> other notes
> ---
> Submit button
The first part of the form would make an entry into the Wines table. The second half would go into the Wine Notes table.
Ideally I would be able to do this at any time from any device, but that seems to be quite complicated without doing MySQL server, so I would also settle for just a file that isn't Filemaker that could only be open on one machine at a time (though in this scenario I wonder how the iOS side would work, if at all).
