What does the isolation property of transactions aim to prevent?Hardware failuresData inconsistenciesConcurrent access issuesDatabase corruptionReview AnswerNext
Solution
The isolation property of transactions primarily aims to prevent concurrent access issues. In a database system, multiple transactions often run concurrently. The isolation property ensures that each transaction runs in a way that is isolated from other transactions, as if it were the only transaction running in the system. This prevents one transaction from reading uncommitted data from another transaction, which could lead to data inconsistencies.
