Description: Read committed is a transaction isolation level in database management systems that allows a transaction to read only data that has been committed by other transactions. This means that changes made by uncommitted transactions are not visible to transactions operating under this isolation level. This approach helps prevent the reading of inconsistent or intermediate data, which could lead to erroneous results in query operations. In this context, ‘committed’ refers to data that has been finalized and is considered stable and valid. This isolation level is particularly useful in environments where data accuracy and consistency are critical, such as in financial applications or other transaction-based systems. By allowing transactions to read only committed data, the risk of conflicts is minimized, and data integrity is improved, although it may lead to increased wait times in high-concurrency situations, as transactions must wait for others to complete before accessing certain data.
