Question

I’m creating an app in which database will be updated via server, or it should be replaced by new one. Can you give me some tips, should I use CoreData or SqlLite. And how it should be updated. I’m using python for parsing data, and then I want to create DB.

Thank you!

This question is not very specific, but if you are not sure what you really need, stay away from CoreData. Start with SQLite and maybe use a light wrapper on top of it. I personally use FMDB.

There are quite a few examples in FMDB on how to select, insert, update etc. Quick example select from the Executing Queries section of the readme:

FMDatabase *db = [FMDatabase databaseWithPath:@"/tmp/tmp.db"];

FMResultSet *s = [db executeQuery:@"SELECT * FROM myTable"];
while ([s next]) {
    //retrieve values for each record
}
