SQLite is great for what it is and its stated purpose, but it's a fundamentally poor database if you actually care about your data. I'm not talking about durability. It's perfectly durable, as in it won't lose your data (well, it might). I'm talking about the lack of actual data types and "everything is a string". I'm talking about the general flimsiness. Hipp even said that is a non-goal because it will bloat the embedded object size in your binary. Because that's what it's for....
Insert a string into an int column? Go ahead, it doesn't care. Use a date function on a text value it doesn't recognize as a date? Go ahead, you'll just get a NULL instead of any indication that your value is wrong for what you think it should be.
It's fine for the address book on your phone, or the bookmarks in your browser. But terrible for server things that are important.
