Although I've never used it, so going based purely on what I've heard/read
SQLight gives much the same functionality as MySQL, the only part where its disadvantaged is in concurrency. If you're only going to have a few users accessing the database simultaneously, then it should be fine, but once you get into the tens of users, you'lll notice a drop in performance (and possibly data inconsistencies)
Things may have changed since I last looked into it, so maybe someone can confirm if this is still the case
