Q1. Q1. What are the components in Azure Data Factory? Please explain.
Pipeline: This is a list of all activities that occur within a logical container.
Dataset:Datasets point to data that is used in pipeline activities.
Mapping Data Flow is a UI logic for data transformation.

Q2. Why do we need Azure Data Factory?
You will find Data Factory mentioned in every Microsoft Azure tutorial. Data flows through many sources in today’s data-driven world. Each source can channel or transfer data using different methods and formats. This information must be efficiently managed before it can be shared over the cloud or other storage platforms. This means that raw data from multiple sources must be cleaned, filtered, and transformed before it can be shared, with any unwanted components removed.
This is about data transfer. Enterprises should ensure that data is gathered from multiple sources, and stored in a single location. Data storage and transformation can be achieved using traditional warehouses. They do have some limitations. For managing their processes, conventional warehouses use customised applications. This is a time-consuming task and it can be difficult to integrate all processes. You need a way to automate or ensure that workflows are properly designed. All these processes can be easily coordinated with Azure Data Factory.
Q3. Q3. What is the limit to the number of integration runtimes you can perform, if any?
Azure Data Factory allows you to perform unlimited integration runtime incidents. There is no limit to what you can do in the Azure Data Factory. There is however, a limit.
