In this Azure Machine Learning data access lesson, students will learn how to access data from various sources and formats using the Machine Learning Studio and the Python SDK. They will understand how to specify the location, format, and authentication of different data sources such as Azure storage, Azure SQL database, or public servers using uniform resource identifiers (URIs). The lesson introduces the concepts of data stores and data assets, which are objects that encapsulate the data source location and the actual data, respectively. Students will gain hands-on experience in creating and using data stores and data assets in the Machine Learning Studio and the Python SDK.
