...but if I need to have a different @fields stored for each database?

Well, I told you the third solution with hashes is the best, because there undefined fields are not a problem at all. With strings you always have to set all fields. You just define the empty string (or a value that is not a valid value) for any field as an empty field. So if for example the dimension is undefined for a database you would have (AA,,N...). But using the empty string is only possible if it is not a valid value anywhere. If that is not the case you would have to use some ugly construct where '@@@' or something means undefined

It print only the fields of the "last" $Database acquired

'$Database' is not '$database'. upper/lower case is important.
