Persistence Layer

The persistence layer is a part of software that manages saving and retrieving data from storage systems like databases or files. Think of it as the interface that allows applications to store information permanently or semi-permanently, ensuring data is consistent and accessible when needed. It separates the core logic of an application from how data is stored, making it easier to maintain or change storage methods without affecting the main application. Essentially, it's the bridge that allows software to keep data safe and retrieve it efficiently for ongoing use.
