Abstract

Abstract Methods and systems for managing replicated objects in a partitioned hierarchical database are disclosed. One method combines partition-wide object identifiers in order according to ancestry to form a database-wide object identifier that identifies a target object relative to all other objects in the database. Each partition-wide object identifier includes a replica identifier and at least one integer value. Suitable integer values include timestamp values, event counter values, random values, and GUID values. Other methods use the identifiers to access objects after a single object or a subtree of objects has been renamed or moved.
