Instead, graph databases like Neo4j or Amazon Neptune are used. These databases are designed to store and process graph data efficiently, supporting complex queries and real-time updates. 2.

Refining with colors Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.
