• MongoDB

• Graph database
• Flat file storage
• SQL database

• MongoDB

• XML database
• CSV database
• Relational database

MongoDB’s flexible data model allows developers to:

• data protection and availability.

• limit data storage to text only
• store unstructured data

• offering indexing support for faster file access

why is JSON documents stored in MongoDB map?

• JSON documents are stored in MongoDB to ensure data is stored in a flat structure.
• to stored in MongoDB for their speed and performance.

• because they are always encrypted.

• to familiar data types found in popular programming languages, such as JavaScript or Python dictionaries.

provides a thorough menu of client libraries with driver support for most programming languages, including PHP, .Net, Java, Python, Node.js, and many others.

• applications.

• Client libraries

• Mongo

stores the JSON documents using a format called BSON, or binary JSON

• YAML
• CSV
• MongoDB

• XML

The nonrelational nature of these documents mean

• They require a fixed data structure.
• They do not support complex queries.
• they can store structured application data as well as semi-structured and unstructured data

• They are only suitable for small datasets.

Unlike relational databases, MongoDB doesn’t use rigid schemas.
