MongoDB is a NOSQL database, cross-platform, document oriented database that provides, high performance, high availability, and easy scalability. MongoDB works on concept of collection and document.
Any relational database has a typical schema design that shows number of tables and the relationship between these tables. While in MongoDB, there is no concept of relationship.
Advantages of MongoDB over RDBMS
- Schema less − MongoDB is a document database in which one collection holds different documents.
- No complex joins.
- Deep query-ability. MongoDB supports dynamic queries using a document-based query language that’s nearly as powerful as SQL.
- Ease of scale-out − MongoDB is easy to scale.
- Conversion/mapping of application objects to database objects not needed.
- Uses internal memory for storing the (windowed) working set, enabling faster access of data.
Why Use MongoDB?
- Document Oriented Storage − Data is stored in the form of JSON style documents.
- Index on any attribute
- Replication and high availability
- Rich queries
- Fast in-place updates
- Professional support by MongoDB
