MongoDB - Advantages

Any relational database has a typical schema design that shows the 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. The 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.

Note: MongoDB's schema-less design and flexible structure make it an excellent choice for applications that require rapid development and iterative changes.

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.

Where to Use MongoDB?​

  • Big Data.
  • Content Management and Delivery.
  • Mobile and Social Infrastructure.
  • User Data Management.
  • Data Hub.
