  • Publication number: 20170308620
    Abstract: A processor executes instructions stored in non-transitory memory storage to receive a pattern query for a graph and determine a set of access constraints corresponding to the pattern query. A determination is made whether the pattern query is effectively bounded under the set of access constraints. A query plan is formed to retrieve a subgraph of the graph when the pattern query is effectively bounded under the set of access constraints. The answer to the pattern query is obtained by accessing the at least one subgraph in response to the query plan.
