Manoj Kumar
Data Analyst
A data analyst is responsible for analysing
data and presenting it in a way that is useful
for making business decisions.
For example, a data analyst might be asked to
analyse sales data for a company to
understand which products are selling well
and which are not. They might use tools like
Excel and SQL to extract the data from a
database, and then use visualization tools like
Power BI to create charts and graphs to help
communicate their findings to the company's
management team.

Manoj Kumar
Data Engineer
Focuses on the infrastructure and tools
needed to store, process, and analyse large
amounts of data.
For example, a data engineer might be asked
to build a system to collect and store data
from sensors on a manufacturing plant's
equipment. They might design and build a
pipeline that captures the data from the
sensors in real-time, stores it in a database,
and makes it available for analysis by other
teams.

Manoj Kumar
Data Scientist
Finally, a data scientist combines the skills of
both a data analyst and a data engineer, with a
focus on using statistical and machine learning
techniques to analySe and understand
complex data sets.
For example, a data scientist might be asked to
predict how many customers a store will have
on a given day based on past data. They might
use machine learning techniques to analyse
data on factors such as weather, holidays, and
past sales to build a predictive model that can
make an educated guess on future customer
traffic.
