Transcripts
hello everyone welcome back to my
channel in today's video we are going to
see about a complete entry and real-time
data engineering project so this data
installing project is completely done
using issue Technologies so I can pretty
much guarantee that after watching this
complete end-to-end data project video
you'll be having a clear understanding
about how to use different Azure
resources to build your data engineering
project so this engineer is going to be
a complete demo of different resources
so the use case that is going to be
covered in this video is one of the very
popular use case and most of the
companies uses this use case to build
the data engine steering project I'm
pretty much sure that it is going to be
really useful and you can also include
this project in your resume and it will
be really helpful for you guys to clear
any kind of issue data engineering
interviews so without wasting further
time let's get started so I would like
to start this by introducing the
different tools that is going to be used
in this project so let's see what are
those so we'll be using issue data
Factory
issue synapse Analytics
issue data bricks
issue data Lake
Azure active directory
Azure key Vault and finally power bi so
as you can see here there are a lot of
different resources so these are the
most commonly used Resources by any data
Engineers to build any kind of data
engineering projects cool so now let's
see how we can use these tools to build
this data in steering project with an
example of an architecture of the
project let's check it out
so as I mentioned before the use case
that we are going to do in this project
is pretty common use case so what I mean
by this common use cases if I introduce
the data source then you'll be getting a
clear idea about what I'm talking about
so the data source that we are going to
use in this particular use cases
on-premise SQL Server database so we all
know that one of the main reasons for
different companies to move to cloud is
to migrate their on-premise traditional
database to Cloud so this is one of the
most common use case right so I thought
like let's take the same use case for
this project so it will be really useful
for you to actually understand this
whole process so inside the database
we're having like six or seven tables so
we are going to migrate this database
completely to Cloud so as part of this
the first step would be using a tool
called assured refractory so Azure data
Factory is a ETL tool I have created a
separate playlist for sure data Factory
where I have covered all the basic
concepts uh like what is social data
Factory in general or what are the
different things that we could do with
it so if you really wanted to get an
understanding about that you can check
that out but if you ask me that if it is
really mandatory to watch those videos
before actually understanding this
project I would say no because all the
concepts will be covered in this video
as well so as I mentioned before
actually data Factory is an ETL tool
which is mainly used for data ingestion
so what we are going to do is the issue
data Factory will be used to connect
with this on-premise SQL Server database
to copy all the tables from the database
and move all the tables to the cloud and
now where the tables will be stored in
the cloud so for that we are using Azure
data Lake gen 2.
Gen 2 is the storage solution in Azure
and the data which is stored in Azure
analyte is pretty cheap so we'll be
using Azure data Factory to connect to
the on-premise SQL database and put all
the data into the Azure data like gento
so once a data has been added into the
Azure data Lake we'll be using a tool
called Ashu databricks to transform all
the draw data into the most curated data
Azure databricks is a big data analytics
tool which is mainly used for high-end
data analytics workloads so in simpler
words we can say that using Azure data
breaks we can actually write the code
either it is SQL or Pi spark or python
all the action development work will be
done inside Azure databricks so which is
mainly used for actually transforming
the data and the next thing is one of
the most important topics that I have
covered in this project is using issue
databricks and issue data like there is
a concept called lake house architecture
so what is mean by Lakers architecture
is say for example Azure data Lake will
be divided into multiple layers so what
I mean by layers is we have different
layers such as bronze layer
silver layer
and gold layer what are the difference
between these lasers for example let me
start with the bronze layer so as
discussed before Aishwarya Factory
connects to the on-premise server
database copies the data and put the
data into the issue data lake so inside
issue data Lake the issue data Factory
puts the data first into the bronze
layer which means that the bronze layer
has an exact copy of what the data looks
like in this data source in this project
we are not going to touch any data
inside the bronze layer and we are not
going to change the format or anything
inside the bronze layer so this is going
to be the source of Truth what are the
main advantages of this is for example
in the subsequent data Transformations
that we are going to do if something
goes wrong you can come back to this
bronze layer and get all the data to try
out which is going to be the same as the
data source so once the data has been
copied to this bronze layer by Azure
data Factory we then use assure data
breaks to connect to this bronze layer
do some data transformation and load the
transform data into the silver layer so
this silver layer and gold layer is kind
of here different levels of
transformation for example the first
level of transformation is silver layer
and the next layer of transformation is
a goal layer so in bronze to Silver
layer the transformation might be kind
of simple like changing the column names
or changing the data types because lot
of times the on-premise kind of data
types and the cloud data types is not
really compatible so we may need to
change few things based on how it is
going to support it into the cloud so
those kind of minimal transformation can
be done in this silver layer and once
the data has been transformed using
Azure databricks and the finer data has
been loaded into the silver layer we
then do an another set of transformation
using same usual data breaks and this
data is going to be loaded finally to
this this gold layer so this gold layer
is the final cleanest form of data so we
all need to have a clean data right so
one of the main tasks of data Engineers
is to clean the raw data into the most
curated data which means that all these
data transformation is done by the data
Engineers using assured outbreaks in
different zones so that's called lake
house architecture so once the data has
been loaded to the goal layer now we are
using another tool called assure synapse
analytics so you can think like Azure
synapse analytics is kind of similar to
what is on-premise SQL Server database
so we can also create the same kind of
database similar to how we can create
using the on-premise SQL database we can
also create all these database and
tables using a synapse analytics and
once these database and tables have been
set up in Azure synapse analytics all
the data that is present in the goal
layer will be loaded to all the tables
that we have created in Asus synapse
analytics so now at the end of this step
the associate snaps analytics will have
a kind of a similar data virusing model
of how it looks like in on-premise SQL
database so you can consider now the
data has been completely migrated so we
are not going to stop here so we are
going to do further analysis on the data
that has been stored inside the SEO
synapse analytics using a tool called
Power bi so this power bi will get all
the data that has been loaded into the
Asus snaps analytics and we could create
a different kind of reports like uh the
charts bar charts or whatever the
reports that we want in power ba so
basically data analyst is the one who
will be creating reports in power bi and
most of the companies where the data
Engineers will also do it so it's better
to understand the full end-to-end flow
of a data engineering project that's the
reason I have covered power bi as part
of this data engine steering project so
apart from this we are also using the
security and governance tools and some
of the tools like we are using Azure
active directory which is an identity
access management tool so all the
security related things and the further
things like creating the service
principle and all of the steps can be
done in the selective directory and all
the other details will be covered in the
subsequent sections and we'll be also
using the Azure key wall to store all
the secrets for example the username and
password can be stored in Azure key
Vault and it can be used to safely
retrieve this information which is kind
of the safest way how the data Engineers
do in real time project so I also wanted
to include this so it will give you an
complete understanding of the overall
data engineering project
cool so now I think you have an
understanding about the use case that we
are going to do in this data engineering
project so this complete entry and data
engineering project will start with data
ingestion and once the data has been
ingested and stored into the Azure data
like then we'll be using Azure
databricks to transform all the data to
the most cleanest form and once the data
has been transformed and loaded into the
gold layer in Australia like we then use
the Asus snaps analytics to create the
database and tables and load the final
gold layer data into these tables and
once the data has been loaded into the
Asus snaps analytics will be then using
power bi to create reports and one of
the main tasks of data Engineers is to
automate all the interior data platform
solution which is pretty much done via
pipelines so what I mean by this is for
example once we have configured this
end-to-end data engineering solution and
say for example if a new row has been
added to any of the tables in the
on-premise SQL database and once we have
run this pipeline Line This pipeline
should get this latest Row from the
on-premise SQL database do all the data
transformation and load that data into
the database and finally this power BH
should reflect the new row that has been
added into the source cool I think you
have pretty much understood the use case
of this project and it will be really
helpful for you guys to understand how
all these data sources work together how
these data sources can be brought
together to build this data engineering
project since there are a lot of
different things to be covered in this
video I have splitted this video into
multiple section so the agenda for this
project would be I'll be starting with
the part one which is the environment
setup and once that has been done we'll
be moving to the part 2 which is the
data ingestion that we have discussed
now and the part three would be data
transformation using data breaks and
part 4 will be data loading and part 5
will be data reporting using power ba
and once that has been done the final
part six will be the end to end pi
testing cool this is the agenda for this
project and we'll be starting with the
part one which is environment setup for
now and for part one environment setup
let's go to the issue portal and see
what are the different resources that we
need to create and what are the other
environment setup that we have to do
let's check it out
