Question

I’m writing an application which needs to store data. A single pack of data is about 4 classes with many dependencies between them. For example, class A has a list of objects B and B has a list of objects C and few more dependencies…

And I wonder what would be better. Keep them in SQLite db or serialize each pack separately and store them in serialized files?

Answer 1

For me the only right solution would be to save the data inside a database especially if there are any dependencies. For beginners it might be hard at the beginning to get into database creation. but after you have created a database in the right form you just have to insert the data and you won’t have any problems in the future if you want to change something or expand your app. With simple serialisation the logic has to be solved inside the app and might cause more problems especially if you have any dependencies.
