This article describes a method for operating a computing apparatus to control access to index records to assure that (a) a user requesting a repeatable read will not obtain a different set of records from an original read because another user has been permitted to modify the index within the first user's key range prior to the first user's commit point, and that (b) a user accessing an index key range will not see changes to the index resulting from an uncommitted update to the index caused by an update to an indexed record.
