What is Neo4j used for?

Neo4j is primarily used for applications that involve complex relationships and require efficient traversal of those relationships. Some common use cases for Neo4j include social networks, recommendation engines, fraud detection systems, and knowledge graphs.

Is Neo4j SQL or NoSQL?

Neo4j is classified as a NoSQL database. Unlike traditional relational databases that use SQL, Neo4j uses its own query language called Cypher, which is specifically designed for working with graph data structures.

Is Neo4j better than MongoDB?

Comparing Neo4j to MongoDB is not straightforward, as they serve different purposes. Neo4j excels at handling complex relationships and queries involving deep data connections, while MongoDB is better suited for applications requiring flexible document storage and scalability. The choice between them depends on the specific needs of your project.

Why Neo4j is better than SQL?

Neo4j can be considered better than traditional SQL databases in certain scenarios, particularly when dealing with highly interconnected data. Its graph model allows for more intuitive representation of relationships and more efficient querying of connected data. This can lead to better performance for relationship-heavy queries that might require multiple joins in a SQL database.

What are the drawbacks of Neo4j?

Neo4j may not be as suitable for applications that don't heavily rely on relationships. It can also be more complex to set up and manage compared to simpler databases. Additionally, while Neo4j has improved its horizontal scaling capabilities, it traditionally focused more on vertical scaling, which could be a limitation for some large-scale applications.

What is Neo4j best for?

Neo4j is best for projects that involve complex relationships and require efficient traversal of those relationships. It shines in scenarios such as:

• Social Network Analysis
• Recommendation Systems
• Fraud Detection
• Knowledge Graphs
