The DataStack encapsulates the data model for the Core Data stack. Each DataStack can have multiple data stores, usually specified as a "Configuration" in the model editor. Behind the scenes, the DataStack manages its own NSPersistentStoreCoordinator, a root NSManagedObjectContext for disk saves, and a shared NSManagedObjectContext acting as a model interface for NSManagedObjects.
