This document discusses big data and MongoDB. It begins by defining big data as huge collections of data that are growing exponentially over time. It then outlines some key characteristics of big data including volume, variety, velocity, and veracity. Some advantages of big data are increased productivity and revenue, while disadvantages include security risks and hardware costs. The document then introduces MongoDB as a popular open-source NoSQL database that uses documents with key-value pairs rather than tables. It compares MongoDB to MySQL, noting that MongoDB does not support joins but is easier to use and provides faster access to data through memory storage. Some disadvantages of MongoDB are limited data size per document and higher memory usage than SQL databases.

5. Big Data
Big Data is also data
but with a huge size.
Big Data is a term used
to describe a collection
of data that is huge in
size and yet growing
exponentially with
time.

9. VolumeVolume refers to the quantity of data generated
and stored by a Big Data system.
The data that is generated is completely heterogeneous in
the sense that it could be in various formats like video, text,
database, numeric, sensor data and so on
The rate at which new data is being generated all thanks to our
dependence on the internet, sensors, machine-to-machine
data is also important to parse Big Data in a timely manner.
Knowing whether the data that is available is coming from a
credible source is of utmost importance before deciphering and
implementing Big Data for business needs.

04 What is Mongo?

15. It’s an open source NoSQL database,
developed for high performance, high
availability, and easy scalability. Collection
and document are the two primarily used
terms/concepts in MongoDB.
These are a NoSQL database. It uses BSON
format for document storage and
communication with its client. BSON is a
binary form of JSON.

Easy on Use
This easy to install and setup
No Complex Joins
MongoDB is based on BSON format – key-
value pair, hence no complex joins here.
Agility
It’s exceptionally easy to add or change
fields in MongoDB.
Many Supported Platform
MongoDB supports wide varieties of
platforms: Windows, Ubuntu, Debian,
Solaris, macOS.
06 Advantages of MongoDB
Due to its nature of using the internal
memory for the storage, it provides
fast access to the data.

27. Disadvantages

2Joins not Supported
MongoDB doesn’t support joins
like a relational database.
High Memory Usage
Due to no functionality of joins,
there is data redundancy. This
results in increasing unnecessary
usage of memory.
Limited Data Size
You can have document size, not more
than 16MB.
