Time-range locking for temporal databases and branched-and-temporal databases

摘要

A method of accessing a version of a row in a temporal database includes checking at least a timestamp associated with the version of the row against a lock criteria for the row. Based on a result of the checking step, it is determined whether to access the version of the row. The version of the row is accessed without acquiring a lock for the row. Lock criteria include time range lock period.
