datapersistens
Datapersistens, or data persistence, refers to the property of data to outlive the process that created it, remaining accessible after a system restart or a crash. In computing, persistence is achieved by storing data in non-volatile storage and by applying integrity and consistency mechanisms to prevent loss or corruption.
Various technologies enable persistence, including relational databases, NoSQL stores, file systems, and object stores. Techniques such
Durability models differ: some systems strive for strong durability with synchronous writes and ACID transactions; others
Common persistence patterns include traditional relational databases, document stores, key-value stores, and event-sourcing architectures that persist
In practice, datapersistens is a foundational capability for most information systems, enabling long-term retention, auditability, and
