GRAPH DATABASES

摘要

There is provided a non-transitory machine-readable storage medium encoded with instructions executable by a processor. The machine-readable storage medium comprises a graph database comprising first-level vertices and first-level edges, each first-level edge linking two first-level vertices, wherein each first-level vertex represents an entity and each first-level edge represents a relationship between two entities. The machine-readable storage medium further comprises instructions to: responsive to a generation of a result set for a query on the graph database, add a second-level vertex to the graph database, wherein the second-level vertex represents the result set of the query; and add a second-level edge to the graph database, wherein the second-level edge connects the second-level vertex to a first-level vertex.
