All right, folks.
So welcome back.
This is Virginia, and this session is about walking off a school choir.
And in a nutshell, what are we going to talk about as how the you are I'll get converted to the second
grade.
OK, so understanding the secretary is the master.
Very important, but you see.
But this is the information there are there are three columns which we read and we have the first we
have we have name, location and interest of some of these students have the interest phone hacking,
some of them are one of them, in fact, is having infosec has the interest the name of the table as
students.
So in the event we created a Debby's, we have to name one database.
And the in the in the in the database, there can be multiple tables and it is stable, whether it be
having multiple columns and there is corresponding information.
All right.
So it's that easy now when somebody send the query when you go to where you are and send some query,
let's say you want to you even go to a search bar on a Web site, let's say example, dot com slash
in the student section and type some in someone's name.
When you go to the students, a question mark represents your query, what you search for.
It even works for Google dot com.
If you search very well, a question mark and name is equal to John.
So usually what you supposed to get is the John Miami Miami.
And the hacking is the interest.
That is the information available on the database.
And that's what you are supposed to see on your Web site, on the Web site and on your browser.
OK, but what really happened?
This information goes to the Web application and the Web application can walk in to and Nesquik ready
to give it to the database.
And that's is how it looks like.
So you see and select anything from any of the different OK from any of the different from the from
any of the anywhere.
In fact, that's what it stymies any OK from students.
So in the student table, if you see the when you go to any tab into the website that belongs to what
people and students where the name is actually John.
So where they call them specify which row you belong to, where a alas are Bob.
So in that case the individual will be selected.
So you see the student is the table here and the name becomes the column here.
And that's how the data get three from the database is OK.
And this is how the entire query really works.
I hope you got the idea.
Will catch you in the next session then you.
