Pipelines and activities in Azure
Azure Data Factory allows you to create data pipelines that move and transform data, and then run the pipelines on a specified schedule (hourly, daily, weekly, etc.).
What is a data pipeline?
A very attractive feature of ADF is that the service offers a holistic monitoring and management experience over these pipelines In a Data Factory solution, you create one or more data pipelines. A pipeline is a logical grouping of activities. They are used to group activities into a unit that together perform a task. To understand pipelines better, we need to understand an activity first.
What is an activity?
Activities define the actions to perform on your data. For example, you may use a Copy activity to copy data from one data store to another data store. Data Factory supports two types of activities: data movement activities and data transformation activities.
