Question:

i am building an app that requires me to store a number of things.

I have a data object consisting of 4 to 5 BOOL variables, there could be 800 - 1000 such objects which i will need to persist.

Am confused how should i program this, should i go for an sql database or Core data, since NSUserdefaults is not an option obviously.

You can easily store them in a plist as @adobels suggested. Your Class would store the BOOLs in a NSNumber and your class implements NSCoding:

- (void)encodeWithCoder:(NSCoder *)coder { [coder encodeObject:member1ToStore forKey:@"yourFirstBoolKey"]; } - (id)initWithCoder:(NSCoder *)coder ...

If all the instances of your class are in an NSArray (or similar Cocoa Collection) you then simply archive and unarchive to a file like

[NSKeyedArchiver archiveRootObject:yourCollectionOfClasses toFile:archivePath] [NSKeyedUnarchiver unarchiveObjectWithFile:[[self archiveURL] path]];

1000 object can be also stored in plist. Generate a .plist file with 1000 of objects of your type. Then check a performance within your app. If it's ok then your app will simpler to write.
