Is MongoDB a NoSQL database?
Yes, MongoDB is a NoSQL database.
The meaning of NoSQL database
NoSQL database is a non-relational database that does not use traditional table-based structures to store data. Instead, it is based on a document, key-value pair, or wide column storage model.
MongoDB's non-relational characteristics
- Document storage: MongoDB stores data in a document, a JSON format object containing a series of key-value pairs.
- No pattern: MongoDB has no fixed pattern, and documents can contain different fields and values.
- Flexible architecture: Data can evolve over time without modifying the pattern.
- Horizontal Scaling: MongoDB can scale out to multiple servers to handle high loads.
Comparison with relational databases
Compared with relational databases, NoSQL databases have the following advantages:
- Flexibility: NoSQL databases allow storage of diverse data types and can easily modify schemas.
- Scalability: NoSQL databases can be easily scaled to provide high throughput and high availability.
- High Performance: NoSQL databases usually have higher performance in certain operations than relational databases.
In short, MongoDB is a NoSQL database because it is based on a document storage model, with schema-free, flexible architecture and horizontal scalability.
