i need some advice.
I am developing an iPhone application (later for Android also) using some social network users. I need to store some data in a database online.
Better to use MySQL with XML or directly use SQLite?
I want performance and stability, and if all goes as I think I might have to handle 500,000 users or more.
I studied a lot about databases, but I would not even take care of his administration, because I'm alone.
Most web services do not support SQLite, but MySQL only.
Can anyone give me some advice with justified?
Thank you to entire community.
