Databases without navigation bar

[Johanovski]

Hi all!

I'm introducing databases to my game, but all examples found about databases works with navigation view and FileManager objects, etc. I'm working with OpenGL and all my code is processed in EAGLView class, so I don't have any UI class (and I don't want to), so I wonder if it's possible to work with databases as is used to in other languages (such as PHP, C++, etc) where you simply make a search with the typical SQL syntax, store the result and then fetch rows and get values without copying them in objects (such as Book object from the Apple tutorial). Any help please?

Thanks!
