<p><p>Creates a dataset group, which holds a collection of related datasets. You can add datasets to the dataset group when you create the dataset group, or later by using the <a>UpdateDatasetGroup</a> operation.</p> <p>After creating a dataset group and adding datasets, you use the dataset group when you create a predictor. For more information, see <a>howitworks-datasets-groups</a>.</p> <p>To get a list of all your datasets groups, use the <a>ListDatasetGroups</a> operation.</p> <note> <p>The <code>Status</code> of a dataset group must be <code>ACTIVE</code> before you can use the dataset group to create a predictor. To get the status, use the <a>DescribeDatasetGroup</a> operation.</p> </note></p>
