 Datasets are categorized into two types based on how users consume them in training. 
 
-* [TabularDataset](https://docs.microsoft.com/python/api/azureml-core/azureml.data.tabulardataset?view=azure-ml-py) represents data in a tabular format by parsing the provided file or list of files. This provides you with the ability to materialize the data into a pandas DataFrame. A `TabularDataset` object can be created from csv, tsv, parquet files, SQL query results etc. For a complete list, please visit our [documentation](https://aka.ms/tabulardataset-api-reference).

This provides you with the ability to download or mount the files to your compute. The files can be of any format, which enables a wider range of machine learning scenarios including deep learning.

 Registered datasets are accessible locally and remotely on compute clusters like the Azure Machine Learning compute. To access your registered Dataset across experiments, use the following code to get your workspace and registered dataset by name. The [`get_by_name()`](https://docs.microsoft.com/python/api/azureml-core/azureml.core.dataset.dataset?view=azure-ml-py#get-by-name-workspace--name--version--latest--) method on the `Dataset` class by default returns the latest version of the dataset registered with the workspace.
