Could you explain what is meant by 'isolation' in the context of databases or system architecture?

In the context of databases and system architecture, isolation is a property that guarantees that concurrent transactions are executed as if they were performed sequentially, one after another.

This prevents issues where one transaction sees intermediate changes made by another, ensuring data integrity.

In databases, isolation is implemented through transaction isolation levels (e.g., Read Uncommitted, Read Committed, Repeatable Read, Serializable), which determine how much transactions can influence each other during concurrent execution.
