Persistent Data

Persistent data refers to information that is stored in a non-volatile medium and remains available across application sessions, system reboots, or power cycles. It is a fundamental concept in computing that ensures data longevity and reliability, contrasting with transient data that exists only in memory during runtime. This concept underpins data storage, retrieval, and management in software systems.

Also known as: Persistent Storage, Non-volatile Data, Durable Data, Persistent State, Stored Data
🧊Why learn Persistent Data?

Developers should understand persistent data to build applications that retain user information, configurations, or state over time, such as in databases, file systems, or cloud storage. It is essential for scenarios like e-commerce platforms storing customer orders, mobile apps saving user preferences, or enterprise systems maintaining transaction logs, ensuring data integrity and availability beyond a single session.
