An Azure data factory is a service that enables you to create, manage, and deploy data-driven applications using the power of Azure. It provides a declarative model for data modeling, a flexible and scalable data ingestion pipeline, and a global deployment network.
You can use it to build data-driven applications that can process large amounts of data in parallel, and to scale up or scale out as needed.
In a data factory, you first model your data using a data modeler. Then, you create an ingest pipeline that uses the data model to transform your data into the format required by your data-driven applications.
The ingest pipeline can use a variety of data sources, including HDInsight, SQL Server, and Azure Blob Storage. You can then deploy your data factory to provide the data-driven applications with the data they need.
The Azure data factory is a powerful tool that can help you build data-driven applications that can process large amounts of data in parallel.
