Although I have not done this yet, I do believe the best approach is the DB approach. A function wrapper to the DB using an ID would allow you to retrieve translations from multiple languages without application reloads, etc. Also, with a local caching mechanism this approach would be very close to the Resource file approach with regard to performance and would allow you the most flexibility. Again, I have not done this and I would like to hear others thoughts as well before investing a lot of time on this effort. I would also like to see a discussion on supporting multi currency but perhaps that should be a new message thread.
