Isolation

See also ACID (Atomicity, Consistency, Isolation, Durability)

Isolation, within the context of database management systems (DBMS), is a fundamental property ensuring that transactions operate independently of each other, without interference or visibility into each other's intermediate states. It guarantees that the execution of one transaction does not affect the concurrent execution of other transactions, preserving data integrity and preventing concurrency-related anomalies such as dirty reads, non-repeatable reads, and phantom reads. Isolation ensures that each transaction sees a consistent snapshot of the database, regardless of the concurrent transactions occurring in the system. DBMS achieves isolation through various isolation levels, such as Read Uncommitted, Read Committed, Repeatable Read, and Serializable, which determine the degree of isolation provided to transactions. Isolation plays a crucial role in maintaining data consistency and data integrity in multi-user database environments, enabling concurrent transaction processing while avoiding data conflicts and data inconsistencies.
