SQLite for iphone

While I was developing my game for iPhone, I had to use SQLite to store the game data (score and other level data), I found a few resources very useful. In these links, http://www.raywenderlich.com/913/sqlite-101-for-iphone-developers-making-our-app and http://mobileorchard.com/iphone-sqlite-tutorials-and-libraries/, is explained, concise manner, how to use SQLite in our apps.
Also is very useful consult the official documentation, http://www.sqlite.org/c3ref/funclist.html.
