Package visgraph :: Module dbcore

Module dbcore

Visgraph supports backing the graph objects with a postgres db.

Classes

DbGraphStore
A DbGraphStore object may be used for all the standard management of node and edge information but may not be used for path queries.

DbSubGraph
A subgraph in the database is basically a forward cached instance of selected nodes and edges in an in-memory graph (visgraph.graphcore.Graph).
