Answering queries using views has proven effective for querying relational and semistructured data. This paper investigates this issue for graph pattern queries based on graph simulation. We propose a notion of pattern containment to characterize graph pattern matching using graph pattern views. We show that a pattern query can be answered using a set of views if and only if it is contained in the...
Answering queries using views has proven an effective technique for querying relational and semistructured data. This paper investigates this issue for graph pattern queries based on (bounded) simulation, which have been increasingly used in, e.g., social network analysis. We propose a notion of pattern containment to characterize graph pattern matching using graph pattern views. We show that a graph...
