Welcome back.
Hope you manage to complete the assignment, if not, please follow along with me in the earlier lessons
we set up the environment for the Roar and the injured and Laius.
But now we want to process the data for our presentation layer.
So in this lesson, let us create the environment for the presentation layer.
You might be wondering why we are creating another container.
Data projects usually have different layers to keep the data for a different number of reasons.
Most importantly, it helps the consumers to understand the nature of the data they're dealing with.
Also, it helps to provide the right access to the right consumers.
For example, you do not want an API to have access to the raw data.
Instead, it should have access only to the presentation layer.
So by splitting them into different layers, you can manage your security and access controls as well.
Different architectures name the layers differently, and there can be any number of layers depending
on the project need, most projects will have at least three layers.
As we've seen, database architecture recommends calling them bronze, silver and gold.
Bronze would have the raw data and silver would have the data with the structure applied and data cleaned,
etc. Gold would have the data as required for reporting and presentation.
We've called us as a raw, processed and presentation and they're synonymous with bronze, silver and
gold.
You can follow these conventions are if you want to change this, please feel free to do so.
Let's be clear in the presentation layer.
This requires us to create the presentation container in our data lake as well as create a mound in
our database workspace so it has access to the container.
Let's start by creating the container first.
Here we are in Microsoft Azure Storage Explorer and this is my subscription, which is the Pacyga subscription,
and this is the storage account that we created for our project, which is Formula One bill.
And under that we got the two containers that we created raw and processed.
And we want to create the third one.
And this is going to be called presentation.
OK, that's now created, so let's switch to our database workspace and create the main point for that,
we have already created our set up scripts, so let's let's navigate to that.
So that is under the Formula One folder.
Under setup, we got the Mount Airy storage and here we created the Mount Ferar as well as processed.
So now we need the third one, which is going to be the presentation.
So let's execute the book, we don't want to execute the entire notebook because we've already created
the and the processed containers and the point.
So let's do what's necessary.
So we need the statement just to set up the secret details and fix gear.
And then we also want the function materials.
So we just we want to miss these, too, and we want to run the presentation.
So materials presentation that amount the new container for us.
That's now Mounter, let's list the main point just to make sure that we can see the mount.
Yeah, we got an empty string out, but our empty list out, but that's because we have got no files
in this folder, no files of folders in this container.
So this has worked.
So the one more thing we need to do here is under configuration.
If you remember, we are keeping the folder pots, so let's keep the folder part percent for presentation
as well so that we can use it in our notebook.
OK, so that's done, so that's everything.
Now, the next thing we want to do is to create the notebook, to transform our data.
