Prerequisites

You have entered the dataset edit page. For more information, see Create a dataset.

Search for a Dataset

On the Dataset management page, you can use the following three search methods.

• Search for only the datasets that you created.

• Search for datasets by name.

• Search for datasets by filtering creation time and creator.

Apply for the Permissions to Edit a Dataset

If you have the development permissions on the workspace, you can view and use all datasets in the workspace. You can edit only the datasets that you created. If you want to edit a dataset that is created by another user, you must apply for the permissions to edit the dataset.

1. On the Dataset management page, follow the instructions in the following figure to apply for the permissions to edit a dataset.

2. On the Apply For Permission page, Select An Approver and enter the Reason For Application, and then click Submit Application.

Apply for the Permissions to Use a Dataset

If you have the analysis permissions on the workspace, you can view all datasets in the workspace. If you need to use a dataset, you must apply for the permissions to use the dataset.

If a workspace member cannot use a dataset, the dataset is displayed in gray in the dataset list, as shown in the following figure.

1. On the Dataset management page, find the dataset that you want to use, and select a data analysis method based on your business requirements. You can select Dashboard, Data Dashboard, Workbook, Ad Hoc Analysis, Downloads, or Data Preparation.

2. In the Apply For Permission dialog box, Select An Approver and enter the Reason For Application, and then click Submit Application.

   Note

   After you apply for the permissions to use a dataset, you do not need to apply for the permissions again when you use other types of data analysis methods.

   

Collaborative authorization

Organization administrators, permission administrators, workspace administrators, and resource owners can grant permissions to users.

1. On the Dataset management page, configure collaborative authorization as shown in the following figure. For more information, see Grant Users the Permissions on Datasets.

If you have created dashboards, downloads, workbooks, data dashboards, ad hoc analysis, or data entry forms based on the dataset, the system displays information about the published resources that are affected by the deletion, including the resource name, owner, modifier, and modification time. You can click the resource name to view the resource details.

Batch Management of Datasets

You can batch transfer owners, batch move resources, batch purge caches, and batch delete datasets.

• You can follow the instructions in the following figure to batch transfer owners.

  If the datasets to be deleted have been used to create dashboards, downloads, workbooks, data dashboards, ad hoc analysis, or data entry forms, the confirmation dialog box displays the published resources that are affected by the deletion. You can switch between different datasets in the Delete Resource list to view the affected resources and their names, owners, modifiers, and modification times.
