[Autogenerated] Here's an example of a simple database
Let's say we have a variable called X.
That has a value of zero.
Let's say we have two threads, T one, and T two,
both want to increment,
the value of X by one and X being the same memory location.
Access by these two threads, is obviously shared.
So here's how that might happen if these are happening at the same time,
each thread will read the value of X at that point in time which in this case,
is zero, they're going to increment them,
based on a register of the processor.
Each one.
Is running on different processor, of course,
and then they will write back the result.
To X, and As it happens, the result will be one instead of two.
So that's a Very simple example of a database and the thing,
is that databases, are notoriously difficult.
To to solve or to resolve because they might not happen all the time.
You might run your application.
1000 times.
And nothing bad seems to happen but then the next run some result.
Is incorrect, that is one of these increments,
going away, and then If you want to figure out what's going on.
You run this application again.
And again,
you don't see the problem because it's based on some
randomness related to the probabilities.
And the exact way.
These threats, are running.
They're not always just implementing the same xss
they're doing other kind of work.
They're in implementing xss from time, to time.
So if this is happening in different times,
you get lucky or maybe be unlucky if you think about it
because then it's very difficult.
To reproduce.
That behavior and the best way.
To avoid databases.
Is In fact, to prevent them.
In the first place, obviously, that might be easier said than done.
But once we get acquainted with how to recognize, and which objects.
We can use to resolve databases.
This will become somewhat easier.
