If you use a typed language (like Java), this is a non-issue. The data will be written in the correct format. But if you use a non-typed language (like Python), this is also not a problem, by the very nature of dynamic languages. So I don't see where the problem is, unless you use SQLite from the console. Moreover, they have constraints that can be added to the db.
