A. The performance of Neo4j and SQL (relational databases) can vary depending on the specific use case and data structure. Neo4j's strength lies in handling highly connected data and complex relationship queries, where graph-based models excel. For such scenarios, Neo4j can provide faster traversal and querying of relationships. However, for simple tabular data and structured queries, SQL databases can be highly optimized and may outperform Neo4j. The choice between Neo4j and SQL should be based on the nature of the data and the specific requirements of the application.
