Tiny database are... tiny, as their name stand for it. It means that they are vertical databases. So to say one column, one value, that's it. One column cannot have multiples values. So to say your database is composed of one row, the one of your values and an unlimited number of columns.

Internal tiny databases mean that they are not shared. So to say once someone has the app set on its device, you cannot inject any additional columns.
