What are the advantages of mongodb database
MongoDB Database Advantages
MongoDB is a popular NoSQL database that is widely used due to its flexibility, scalability, and other advantages. Listed below are the main advantages of MongoDB database:
1. Document Data Model
MongoDB uses a document data model, which allows users to Storing data. Documents can contain nested fields and arrays, making data modeling easier and more intuitive.
2. Horizontal scalability
MongoDB can be horizontally scalable to multiple servers through sharding. This allows the database to scale as data volume grows without experiencing performance degradation.
3. Query flexibility
MongoDB provides a rich query language that supports complex queries and aggregation operations. Additionally, it allows the use of secondary indexes to optimize query performance.
4. Data replication and fault tolerance
MongoDB supports data replication to ensure data redundancy and high availability. Replica sets and sharded cluster features ensure data is not lost in the event of server failure or other events.
5. JSON support
MongoDB uses JSON (JavaScript Object Notation) as its native data format. This makes integration with front-end applications easy since JSON is a widely used standard format.
6. High Performance
MongoDB’s memory-mapped architecture and asynchronous I/O operations enable it to achieve high performance, even when processing large amounts of data.
7. Open Source
MongoDB is an open source database, which makes it highly customizable and free to use. Community support is active and there are tons of resources available.
