SOURCES OF DATA
A huge amount of data is being generated continuously through various data sources, such as log
files generated by customers using the mobile or web applications, online purchases, in-game
player activities, social media posts, financial trading platforms, and communication between the
smart appliances and the connected devices. Further, the data collected from various sources is
maintained in tabular forms to generate datasets. Some main sources of data are:

Online Shopping

You all use many online shopping websites to purchase different products on a regular basis. You
submit your registration details, like name, age, gender, and address. This information gets stored
in the database of these websites. With the help of data science, the websites collect the
information, like what kind of products you normally purchase, what your average budget is, and
at what time you do shopping. Using this information, these websites start recommending related
products and offers.

Online Gaming

The children who play online games can see advertisements related to games and sometimes
study-related topics as well. As the children get registered on the basis of their age and class, data
science helps advertisers make the decision on what type of advertisement should be played
between games.

Online Ticket Booking
Whenever you do an online booking for a flight, bus, train, or movie ticket, you provide all your

personal information, like name, age, gender and address. The database stores this information
along with your travel information and starts sending offers and suggestions for your next tour.
Social Media
You all use many kinds of social media platforms, like Facebook, X, Instagram, LinkedIn, etc.

You post many events and personal information on these sites. Sometimes, you watch video clips
or make purchases from these sites as well. Again, based on your choice, you get
recommendations and suggestions from these portals.

Online Billing
You use an online platform to pay electricity bills, recharge mobile phones, fill up vehicles with
fuel, buy groceries, and do a variety of other household tasks. Here, data science helps you by
reminding you of the dates of billing, offering better plans, planning your budget, and many more

activities.
