Hi,
I have some doubts about the future development of my application; now it is essentially a database application which shows informations of a magazine's issues (articles, stories, authors, etc). All the data are stored in a sqlite file and the program queries it. Periodically I release new version of this file that the program downloads and installs. With the next main version I'd like to let the user add annotations, rate articles, etc. and, perhaps, build a sort of social network. But these personal informations must be stored somewhere; it can't be the file above since il will be replaced by new versions; I can't use a second database file because it isn't possible at the same time query two databases. Perhaps I should rethink the entire data structure, but this is a new field for me and I do not know what would be the best way. So here I am asking your suggestions on this matter or pointing me to a similar project.
Very thanks
