Core Data Stack

The Core Data Stack is a framework used in software development, particularly with iOS and macOS apps, to manage and store data. It consists of several key components: a data model that defines the structure of the data, a persistent store that saves the data to disk, a managed object context that acts as a workspace for data manipulation, and optional objects that help with data queries and updates. Essentially, it helps developers efficiently manage complex data relationships and ensure that data is saved and retrieved effectively, enabling rich app functionality without overwhelming complexity.
