4. What is MongoDB?
MongoDB is an open-source document database
that provides high performance, high availability, and
automatic scaling.

5. MongoDB Nexus Architecture

6. Knowing MongoDB Terms

7. Document Database
A record in MongoDB is a document which is a data structure composed of field and
value pairs.
MongoDB documents are similar to JSON objects.
MongoDB internally stores the data as BSON (binary JSON)
The values of fields may include other documents, arrays, and arrays of documents.

8. What is JSON?
JSON stands for JavaScript Object Notation
Characteristics:
Lightweight data-interchange format
Easy for humans to read and write
Easy for machines to parse and generate

10. Document model

11. Document model benefits
Agility and flexibility:
Data model supports business change
Rapidly iterate to meet new requirements
Dynamic schema supports fluent polymorphism.

12. Document model benefits
Intuitive, natural data representation
Eliminate ORM layer
Developers are more productives
Documents (i.e. objects) correspond to native data types in many
programming languages.

13. Document model benefits
Reduces the need for joins, disk seeks
Embedded documents and arrays reduce need for expensive joins.
Programming is simpler
No foreign keys
