Database in iOS application: Sqlite vs XML + XPath? -


my app needs read data exported sql database. in addition reading, app should query database in order find relations between different data. potentially, amount of data can large. of course, should responsive , not impact negatively of user experience.

here doubt: going export database in xml format , run queries using xpath i'm not 100% sure approach going efficient enough, if number of records in database around thousands.

what can guys tell me efficiency , performance of xpath in ios? solution large xml database?

would sqlite better , more efficient approach? using sqlite, risking make app heavy?

thanks!

you definately should use sqlite on xml in ios apps. recommend best wrapper such database: https://github.com/ccgus/fmdb fmdb + making queries in background threads performance of app shouldn't affected @ all, big db.
