Claim Text:
1. A computer-system-implemented method for requesting desired information from a graph database, the method comprising: executing a first query against the graph database storing a graph, wherein: the graph comprises nodes, edges between the nodes, and predicates to represent and store data with index-free adjacency; and the first query identifies a first edge associated with a first predicate that specifies one or more of the nodes in the graph; receiving a first result in response to the first query, wherein the first result includes a first subset of the graph; executing a second query against the first subset of the graph, wherein the second query identifies a second edge associated with a second predicate that specifies one or more of the nodes; and receiving a second result in response to the second query, wherein the second result includes a second subset of the graph; wherein the results of the first query and the second query are used in concatenated queries, thereby avoiding joining intermediate results.
