RodaSpell is a small and strong Spell corrector. And it isnít a simple Spell corrector, if a word isnít good writing, it will suggest you the better one option.
RodaSpell could be used MySQL or SQLite but doesnt care wich one you choose, couse the database is just used like a repository of the words and the phonetic number.
I recommend SQLite for a small list of words, cause SQLite is smaller and with smaller memory requirements. But if you wanna a faster result with up to 2000 list of word, use MySQL
Sorry for my english. :D
