ACID transactions, specifically database isolation levels, are important to ensure data consistency and correctness in a multi-user database system. In a multi-user database system, transactions may overlap and access the same data concurrently, leading to conflicts and inconsistencies in the database if not properly managed. Take a look at the presentation by Ante Javor, discussing ACID and isolation levels and the discussion at the end.
