Abstract
A plurality of transactions is handled in a database. Each transaction includes a plurality of operations on at least one record in the database with at least two of the transactions being handled concurrently. Thereafter, a temporary timestamp is assigned to each record. The temporary timestamp are based, at least in part, on the corresponding transaction. Further, a final timestamp is assigned to each record with a commit operation. It can later be determined, using a visibility function and based on the assigned temporary timestamps and final timestamps, which of the records are visible in a consistent view for a first transaction. Based on such determination, access can be provided to those records determined to be visible to be accessed to the first transaction.
