Mongo DB Database - Day 32

MongoDB is a cross-platform, document oriented
database that provides, high performance, high
availability, and easy scalability. MongoDB works on
concept of collection and document.

MongoDB - Advantages

• 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

Insert Document Syntax

])
