The data-driven workflow in ADF orchestrates and automates data movement and data transformation . Azure data factory helps organizations across the globe in making critical business decisions by collecting data from various sources such as e-commerce websites, supply chains, logistics, healthcare, etc . , transforming that data into a usable and trusted resource using multiple operations like filtering, concatenation, sorting, etc . , and loads that data into a destination store.  \nSource: GitHub  \nThis article was published as a part of the Data Science Blogathon  .  \nBasic Level Azure Data Factory Questions  \nQ1 . What is Azure Data Factory?  \nADF is a cloud-based data ingestion and ET L ( Extract, Transform, Load) Azure service. ADF helps organizations across the globe in making critical business decisions by building complex ET L processes and scheduled event-driven workflows to process data which later can be used by various reporting tools for storytelling purposes .  \nSource: Microsoft  \nQ2 . How Azure Data Factory Makes the Process of Creating a Data Pipeline Easy?  \nADF makes the process of creating a data pipeline easy by providing built-in connectors for data ingestion and orchestration, giving various activity options to perform operations such as copying data, for-each loop, look-up, etc . , validating, publishing and monitoring pipelines, continuous integration, and continuous deployment support to the pipelines .  \nQ3 . What are the Different Types of Activities Supported by Azure Data Factory?  \nBelow are the different types of activities supported by ADF:  \n Data Movement Activities: Activities used to move data from one data source to another in a data pipeline are known as Data movement activities . For example, copy activity can be used to copy data from ADLS to Azure SQL.  \n Data Transformation Activities: Activities used to perform data transformation in a data pipeline are known as Data transformation activities . Data Flow Activity, Azure Functions Activity, Databricks Notebook Activity, etc . , are examples of data transformation activities .  \n Control Activities: Activities used to build conditional, sequential, or iterative conditional logic in a data pipeline are known as control activities . Lookup Activity, Until Activity, For-Each Activity, etc . , are examples of control activities .  \nSource: [docs. microsoft. com](docs. microsoft. com)  \nQ4 . Solve the Project Scenario based on Question 1 .  \nYour data team is building an ETL pipeline for a client. You want to generate output files from Azure Data Factory which are optimized for read-heavy analytical workload s and support the columnar format. What should be the file format of output files? The generated output files should have Parquet format as Parquet stores data in columns and are optimized for read-heavy analytical workloads .  \nQ5 . What are Annotations in Azure Data Factory?  \nAnnotations are additional informative tags that help in filtering and searching data factory resources such as datasets, pipelines, linked services, etc . For example, if you are working as a team lead for a large data processing project for a client ABC that uses ADF containing 10 pipelines . To avoid confusion in the data processing sequence, we can label each pipeline with its primary purpose: ingest, transform, or load using annotations . When we are monitoring pipelines, these annotations must be available to perform searching, grouping, and filtering.  \nQ6 . Why do we need Azure Data Factory?  \nAzure Data Factory is a cloud-based data integration service that enables you to create, schedule, and manage data pipelines for ingesting, preparing, and transforming data from various sources to various destinations . It’s useful for ETL ( Extract, Transform, Load) processes and data m","cbCaiqxVwEenqRNx","https://ap.wps.com/l/cbCaiqxVwEenqRNx","pdf",260502,"English","# Introduction\n## Basic Level Azure Data Factory Questions\n## Intermediate Level Interview Questions","[{\"question\":\"What is Azure Data Factory (ADF) and what does it do?\",\"answer\":\"ADF is a cloud-based data ingestion and ETL tool.
