ipad - searching in large amount of info in a single file on iphone -

I want to store a list of people, while each person has some information related to it, for example location and phone For the number and e-mail address.

I want to store about 10,000 people in this list. After that I want to search this list dynamically (after typing each letter, the database is searched for new matches of the string written in the search box). [If this search process Is a scientific name for me, please tell me this please :))

My question is, should I use the best performance in my implementation?

SQLite, XML, plist ???

And what is a tutorial about this type of search?

In advance thank you

You must use SQLite for this , And the CoreData abstract layer probably will probably be a good idea unless you already have any promotions on the SQLite call. The core data will be a good place to start on how to do this document. The applet provides many examples that are similar to what you are doing.
