Multiversion Databases

Multiversion databases manage multiple versions of data records simultaneously to improve performance, concurrency, and reliability. Instead of overwriting data directly, they keep previous versions, allowing multiple transactions to access consistent data states without conflicts or delays. This approach enables faster read operations and helps ensure data integrity even when multiple users are updating the database at the same time. Think of it like having a history of edits that can be referenced or restored, making the system robust and efficient for complex, high-demand applications.
