Isolation Levels

Isolation levels are rules that determine how transactions (sets of database operations) interact to ensure data accuracy and consistency. They control the visibility of changes made by one transaction to others, balancing data integrity with system performance. Higher isolation levels (like “Serializable”) prevent interference but may slow processes, while lower levels (like “Read Uncommitted”) allow more concurrency but risk seeing unconfirmed or inconsistent data. Choose the right level based on the needed data accuracy and system efficiency, minimizing errors without unnecessary delays.
