Data Science is the most revolutionary technology of the era. It's
all about deriving useful insights from data in order to solve real-
world complex problems. The first module is a reduction to data
science that covers all the basic fundamentals of data science
followed by this. The next module is the supervised learning
algorithms module where we 'll start by understanding the most
basic with them or which is linear regression. We 'll discuss how
Walmart is using insightful patterns from their database to
increase the potential of their business. After that. We will see
what exactly data science is, then we 'll move on and discuss who
are data scientist is where we will also discuss the various skill
sets. After this we will discuss how data is extracted processed
and finally use as a solution. We'll discuss a use case of the k-
means clustering after which we can move on to see the various
data science job roles such as data analyst data architect data
engineer. We produce 2. 5 quintillion bytes of data each day. And
this is only accelerating with the growth of IoT or Internet of
Things. IoT data is measured in zettabytes and one zettabyte is
equal to trillion gigabytes. According to a recent survey by Cisco.
It's estimated that by the end of 2019 the IoT will generate more
than five hundred zettabytes of data per year. This number will
only increase through time.
Social media is generating a lot of data for us. Data science is a
simple process that will just extract the useful information from
data. Walmart is the world 's biggest retailer with over 20,000
stores in just 28 countries. We pay bills online. We even buy
homes online these days you can even sell your pets on oil
excuses. Walmart is currently building the world 's biggest. Good
Cloud, which will be able to process two point five petabytes of
data every hour now. The reason behind Walmart success is how
the user customer data to get useful insights about customers
shopping patterns. Walmart found out that strawberry Pop-Tart
