CoreData or Sqlite which should be used in iphone application for local storage of data

I want to 开发者_开发技巧develop an iPhone application. On which i have to use DB to store data locally.But i am confused about whether i should use Sqlite or Coredata.My application has a centralised database and i am taking data from that DB using Web service.

Well, sqllite works quite well and is what CoreData uses behind the scenes anyway. But if you don't already know SQL, it can be complex to use.

CoreData is sort of easier to start, but complex to figure out how to work. It performs better though.

In the end you are probably better off learning CoreData and proceeding that way. Just don't do ANYTHING with CoreData in background threads until you are comfortable with how it works already, as that is a whole added layer of complexity fraught with peril.
