Multiversion System

A multiversion system is a technique used in databases and computer systems to manage multiple versions of data. Instead of overwriting existing information, the system keeps multiple versions of the data, allowing users to access different states of that data over time. This is particularly useful for transactions, where users can read data without affecting ongoing changes. It enhances data integrity, prevents conflicts, and improves performance by enabling concurrent access. Overall, a multiversion system helps maintain a coherent and reliable view of data in dynamic environments.
