ABSTRACT:
User-level bookmarks are initially created at a specified offset in a large object (LOB) of a database and automatically updated to reflect a new offset, if necessary, after database updates. By logically linking the bookmark to a data element, the bookmark continues to point to the same logical data element as it did before the update. An API provides the functionality of immutable bookmarks by automatically changing the offset of the bookmark following sliding inserts or deletions of data to the database.
