0 0 votes Answer B Explanation of Thomas write rule It is timestamp-based concurrency control. It states that, if a more recent transaction has already written the value of an object, then a less recent transaction does not need perform its own write since it will eventually be overwritten by the more recent one. Label each value with a write timestamp (WTS) WTS indicates the timestamp of the last transaction to modify the value. If the write timestamp of the object is greater than the time stamp of the transaction performing a write,, the write is discarded sh!va answered Jul 21, 2016 sh!va comment Share Follow 0 reply Please log in or register to add a comment.
