Question

I need to create an app linked with a remote database! Is mysql the best solution? Is Sqlite an only-local solution?

I use the following method and I would to know if it is the best way!

NSString *evento = @"1";
NSString *filtro = @"CAC2";

NSString *strURL = [NSString   
stringWithFormat:@"http://www.xxxxxxx.com/Scripts/Evento/WIGriceviTipo.php?  
evento=%@&filtro=%@",evento, filtro];

NSData *dataURL = [NSData dataWithContentsOfURL:
               [NSURL URLWithString:strURL]];

NSString *strResult = [[NSString alloc] initWithData:dataURL   
encoding:NSUTF8StringEncoding];

strResult = [strResult stringByTrimmingCharactersInSet:[NSCharacterSet       
whitespaceAndNewlineCharacterSet]];

mostra.text=strResult;

NSLog(@"%@", strResult);

Why not use Core Data? I do lots of remote database interaction and use CD for the local storage and just pass all the data to a web-service that digests it, checks for data integrity and then passes along the data to the database.

Core Data is a much easier learning curve than you might think and if you use a third party library like Magical Record, it is even easier.

As far as the web server database goes, MySQL is the best option (IMO) if you are using a Linux based platform, SQL Server becomes an option if you are going the Windows Server route.
