While global revisions are a good way to provide correct auditing of relations, some people have pointed out that this may be a bottleneck in systems, where data is very often modified. One viable solution is to introduce an option to have an entity "locally revisioned", that is revisions would be created for it independently. This wouldn't enable correct versioning of relations, but wouldn't also require the "REVINFO" table. Another possibility if to have "revisioning groups", that is groups of entities which share revision numbering. Each such group would have to consist of one or more strongly connected component of the graph induced by relations between entities.
