Database in IPHONE / IPAD

[mr_ael]

Hi, My name is Alfred.
I'm new in this forum, just googling and become a member.

I just learn the IOS Programming last week. I'm reading this book, "A Beginners Guide - IOS SDK Programming".
I read alot and try alot already.

And now my question is about the database in iphone or ipad. Because I want to build one apps that retrieve data from the database. In that book said that iphone and ipad are using SQLite Database, thats mean we gonna build our own database first including the structure, etc. And we also must input our data.

How about if I want to retrieve data but not from the SQLite Database, but from the other database engine? lets say from my I have a domain, I created a database. How can I use that database without using the SQLite?

another example I make an android apps for my university. The apps retrieve the data from the university database. How can I retrieve the data using IOS Programming? Do I need a php to connect through the database like the android?

Thanks before. Sorry for my bad english. I'm waiting for your answer guys. Thanks.

You have to use sqlite if you database is native on your iOS device. However, you can use any database if you are retrieving the data over the network. In those cases, it really doesn't matter what the database it, essentially you are using data from the internet.

You need to look into coredata if you are using native db sqlite.

You need to look into libxml, JSON if you are trying to retrieve data over the network.
