Abstract
A method of assigning timestamps to data items processed by a transaction. The method sets initial upper and lower limits for a transaction timestamp that will be applied to data items processed by the transaction if the transaction does not abort. The upper and lower limits are incrementally updated as data items are processed and time intervals are requested by the transaction. The lower limit is incrementally updated as data items are processed to ensure that write-write, read-write and write-read conflicts are avoided. A transaction timestamp is selected that is greater than the lower limit, but less than the upper limit.
