Azure data factory is a cloud-based platform. The platform or rather an eco-system allows you to develop, build, deploy and manage the application on the cloud storage. The cool thing about the platform is that it allows you to do everything on the cloud. That said, your physical device’s storage memory is saved. And all the stuff that you do is stored on the cloud.
Seeing the Azure platform from the future point of view, it has tremendous scope. When Microsoft has come up with a concept, it is sure that it is futuristic. Hence, learning it right now is an excellent move towards your career.
You must know how practically Azure data factory works before using it. Let us consider a scenario where you are having a lot of data and you are unable to sort it. Azure data factory helps you to analyze your data and also transfer it to cloud.
To introduce you to Azure data factory, we can say that Azure data factory can store data, analyze it in an appropriate way, help you transfer your data via pipelines and finally you can publish your data. With the help of some third party apps like R and spark, you can also visualize your data.
Prerequisites for learning Azure Data Factory
The Azure Tutorial is basically designed for developers who have Azure subscription. The implementation of Azure is going to be fallen in website, application and software development. Hence, the ones who are keen to do such projects, Azure will be more beneficial to them.
Azure data factory tutorial
If you want to use Azure data factory, you must have knowledge about Azure data factory tutorials. Let us know what exactly is Azure data factory tutorial and how it is useful. With the help of Azure data factory tutorial, you will know how Azure data factory actually works. You will also be made aware of the importance of Azure data lake.
Azure data factory tutorial will guide you to copy your data from SQL of Azure to Azure data lake. After that you can also visualise your data using third party sources like Power BI.
You will also learn more about Analytics. Analytics can also be operated by using U SQL for processing the data.
Nowadays, we are getting a large number of data from many resources. Result of such increasing data is that it gets very difficult for us to manage, store and analyze the data at the same time. That is why we must use Azure data factory, which helps you to store, analyse and transfer the large amount of data.
There are various steps and terms associated with Azure data factory such as pipelines, Azure data lake, storage. Let us learn about all these terms and get detailed information about it. As discussed earlier, if you are having stored data then azure data factory collects that data, transfers that data through pipelines, and finally you can use that data to publish or visualize using various sources.
Here is a step by step illustration.
Collect the data and connect it: Data in the pipeline can be copied or transferred to the cloud source data stores or the same data can also be moved from on-premises.
Transforming the data: computer services can help you in transforming or processing the data which is already centralized in the cloud. Computer services are Hadoop, spark, R etc.
Publishing the data: Data which is already structured, analysed and well refined is now collected into the Azure data factory warehouse. It is monitored and published in the Azure data warehouse.
Monitoring your data: PowerShell, Azure monitor is available on Azure portal which helps you in pipeline monitoring. Azure data factory works on data driven workflow with structure so that it can easily move and transfer the data. Azure data factory does not work with a single process. It has various small components which work independently, and when combined, it performs successful operation.
Pipeline: Unit of work which is performed by logical grouping activities is called a pipeline. Pipelines can be single or multiple. Various tasks are performed by pipeline at a time, such as transforming, analysing and storing
Activity: processing steps of the pipelines are represented by the help of Activity. For example – copy activity is widely used to move data from one source to another source.
Datasets: data sources which are present in the data stores are represented by the data set structures. We can also classify that data in our activities.
Linked Services: It can be defined as a bridge which is used to connect Azure data factory to the external resources. Computer resources and data stores are types of the linked services.
Triggers: Triggers, as the name suggests, triggers something. When pipeline execution is needed to be disabled then the unit of processing determines it with trigger this unit is known as trigger. Another feature of trigger is that we can schedule this process pre-handed, so that at a particular point we can trigger and disable the process.
Control flow: It is an extension of activities which are carried out by pipeline. We can also say it is like a thread or chain which arranges activities in a sequence.
Components of SQL Data Warehouse
Data Warehouse units:
Data Warehouse Units (DWUs) are the measure of data or resources that are received by SQL. This memory is allocated to the data warehouse.
Scan/Aggregation: Scan/Aggregation scans the query generated. This work is I/O and CPU based.
Load: Load is the measure of how much data could be actually talked up by the data warehouse.
Create Table As Select (CTAS): CTAS enables users to make a copy of the table. It reads, operates, distributes, and writes the table.
Structure of Azure data factory

Let us get into more depth about Azure data factory structure. Let us consider you are having some data, it can be in the form of mobile data or any other kind. Now this data can be transferred to your output cloud using a pipeline. Pipeline is SQL or hype which carries various operations on data and transfers it to the output cloud. We will learn more about pipelines in a few more upcoming points. Output data is the structure form of your data as it is already transformed and analyzed in the pipeline. Finally this data is stored in the lake data.
Azure DevOps Organization works very similar to any physical organization out there. It is a group or division of alike projects combined together.
Projects in DevOps are agile and continuous testing, integration and the deployment of the same project is ongoing.
Creating Azure Data-Factory using the Azure portal
Step 1: Find – \”create a resource\’ and search for \”Data Factory\”. Click the create icon.
Step 2: Give your data factory a name. Select your resource group. Give it a path to and choose the version you would like.
Step 3: Click on create.
Thus your data factory is ready to be filled with more data.
Azure SQL Stretch Database & SQL Data Warehouse
SQL Stretch Database:
SQL database acts as an interface between the user\’s raw data and Azure\’s data lake. SQL database is processed and transformed to the cloud. The data is processed to be classified further. Hot data is the one which is accessed frequently by the users. And cold data is one which is not accessed quite frequently.
To recover or fetch the data, whenever needed, we simply need to type a query. And the data, wherever it may have categorized in, is searched out.
Advantages of SQL Stretch Database
The on-premise storages are expensive and they take some extra efforts to fit in the database queries. SQL is comparatively easier and cheaper than most of the other storage platforms. SQL extracts the data on cloud. Hence it is faster, and it\’s maintenance is minimal too.
While transforming the data, SQL keeps it extremely safe and secure. It\’s encryption is protecting the privacy of data even while transformation of data is in process. Advanced security of the SQL keeps the stretch database absolutely secure and safe.
SQL database warehouse is a fully cloud-based platform and hence extracts the data with ease. It uses parallel architecture to fetch out whichever type of data is searched for. In the parallel architecture, the data is inquired with the control mode, and passed on to the computer mode. Both the modes and processes in between are made to work parallelly.
Azure DevOps helps in coordinating with the support team to make the Azure application development and changes. That said, Azure DevOps allows you to modify the minor changes in codes and infrastructure without having developers to interfere.
Services of Azure DevOps
Azure Certification Training!
Not only the Azure DevOps allow you to modify minor changes, but it also helps the user deploy and build the applications. Its services are scattered wide. Right from building to developing to deploying, all the functionalities are performed in sync on the single cloud platform.
Azure Repository is very analogous to git repository. All the codes are stored in Azure repository to build up an application. The tool is used by developers to code and build. Specific developers are granted access to a particular git part of the code.
Azure pipeline works as a pipeline to the destination path. Wherever the code is required to combine or to function on a particular time, this pipeline inserts the code there.
Board is something where you can create activities, track activities, and distribute the task of development to the team.
Test plan is browser-based testing done with automation instead of having manual testing to be done.
Azure data factory, requires NuGet package, npm, Maven package, and many other such packages. Artifacts is compatible with all the packages and hence is very useful.

All you need to know about Azure Factory Data lake file system.
Microsoft Azure Data Lake: Working of data can be understood in three basic steps. First step is to get you output data which can be in mobile data form or any other type than it is transferred to the Azure factory data and you can visualize your data in the third step using any third party apps like R, apache, Spark etc.
There are another two vital components which you should be aware of. First concept is storage, storage of data can be in Gigabytes, terabytes etc. This data is wide and large information. You can analyze this data as structured or unstructured data. Structured data has specific information in it and unstructured data is a lobby type of data.
The second concept is analyze, now analyze is also divided into two types. First type of
Analysis is a monitor type where you can generate your data. For example data of buildings, location, construction cost, area of building, life of building, amount of live load and dead load it carries. All this data of building is available to you in a structured manner.
Another type of analysis is use of Azure data factory in a card. If you have a debit card you can know it\’s transactions, location of card, it\’s expiration date and much more. These are the two main concepts you must know about Azure data factory.
