MongoDB - Advantages


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. Number of fields, content and size of the document can differ from one document to another.

  • Structure of a single object is clear.

  • No complex joins.

  • Deep query-ability. MongoDB supports dynamic queries on documents using a document-based query language that's nearly as powerful as SQL.

  • Tuning.

  • 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

  • Auto-sharding

  • Rich queries

  • Fast in-place updates

  • Professional support by MongoDB
