PROVIDING UNIQUE VIEWS OF DATA BASED ON CHANGES OR RULES

摘要

A method comprises storing, in a revisioning database, data objects; a first plurality of data objects is associated with a base realm representing data shared across all database users; a second plurality of objects is associated with child realms, child realms represent data local to a project, and users are associated with child realms; the revisioning database associates each object to a realm identifier and to a version identifier for a plurality of versions of the object, each of the versions represents a change to the object by any user; receiving a request to view a third plurality of objects; selecting, based on the base realm, the particular realm, the version identifier for the third plurality, and one or more rules of the particular realm and the user, objects in the third plurality viewable by the user; creating and providing a data view that includes only the selected objects.
