So what is database?
As a beginner, you might be like, what am I doing with database?
Database is very important as a developer.
So database is a place you store and manipulate and retrieve data.
So you can actually store that idea.
You can actually retrieve data there.
And you can also manipulate the data.
And this data is often stored inside a computer server.
Let me go ahead and look this a Facebook as an example.
Facebook is a place you connect with different people from all over the world, and every information
about us or about our friends, and also including our likes and our comments are stored inside a database.
So once you view if friend's Facebook page to check out information about them, the responses are coming
from database.
So those information are there 24 over seven.
Every time, anytime you need it, you go ahead and retrieve that information and that the owner of
that information can actually manipulate the database by updating the bio, updating the age, updating
information, profile page, profile pictures and so on.
And you can also store on database by including your data.
Creating a new account and inserting your data into Facebook.
So this is the same with Amazon, eBay or any other platform out there.
Let's go ahead and say this is eBay and I have this shoe right here.
And the name of the shoe is Jordan four Retro Metro White uh, Oreo.
Uh, I can actually pronounce that correctly, but if you come back here tomorrow, you're going to
see this name, or this name might have changed.
So this name was actually, uh, stored right in here.
And anytime I need a name, it always comes out.
So if the owner of this shoe comes back, he or she can change this to me.
The black or blue or anything, or even change the entire name or even delete this.
So this is what we call manipulation.
This is where manipulation comes into play.
You can actually manipulate the database.
You can actually do whatever you want.
You can actually edit, update and do so many things.
So this is what databases are about.
So every information about this shoe and you can see all the stuff in there.
Through Alonso 93.
Results from all of this are coming from database.
Okay.
Every information, all the shoes are stored in a database and information about them are coming from
the database.
All right.
So if I keep scrolling down, you can actually see that everything about this shoe is from a database.
So if you go ahead and check the reviews all the reviews are stored in a database.
And this is our Amazon.
So this is a book by Mark robo Practical Python Programming, 100 Practical Python Programming practices
and projects.
And everything is stored in a database including the descriptions, the rating and the reviews.
So in summary, the database is a place you can store, manipulate and retrieve data.
So we will be learning in this course is to learn how we can be able to create, database, store,
update, save, manipulate, do any kind of thing with a database.
And in that way we can be able to learn how to manage a database, create a database and manage it by
ourselves.
So let's go ahead and move on to the next video lecture and kick off immediately.
Thank you and see you then.
