Datasets
Datasets are used to manage time-series data files for forecasting and data evaluation. You can create a dataset first, upload CSV or TsFile data files, and then select the uploaded dataset directly in later workflows such as data evaluation.
Create a Dataset
- In the left sidebar, open Dataset Management and select Datasets.
- Click + Create Dataset in the upper-right corner.
- Enter a dataset name.
- Optionally add a description and tags.
- Click Create Dataset.
| Field | Description |
|---|---|
| Dataset name | Required. Use a meaningful name, such as “Weather” or “Device Temperature” |
| Dataset description | Optional. Describes the data source or purpose |
| Dataset tags | Optional. Used for categorization and search. Up to 3 tags |
After creation, the dataset appears in the list. The list shows the dataset name, tags, file count, size, creation time, and update time.
Upload Data
- Open the upload page in one of three ways: click Upload Data in the upper-right corner of the dataset list, click the upload button on the right side of the target dataset row, or open the dataset details page and click Upload Data in the upper-right corner.
- Select the target dataset.
- Click the upload area to select a file, or drag a file into the upload area.
- Wait for the system to complete format validation.
- After validation passes, click Upload Data.
Supported file formats:
| Format | Description |

| TsFile | The system validates the file format |
Currently, only CSV and TsFile files are supported. You can refer to the template file on the page for the CSV data format.
View Data
After upload, click the dataset name to open the dataset details page.
On the details page, you can:
- View the dataset ID, size, creation time, and update time
- View the uploaded file list
- View, download, or delete files
- Open a file details page to view metadata, data tables, and visualization charts
Data Evaluation
After data is uploaded, click Data Evaluation in the dataset list to evaluate the dataset quality.
For evaluation metrics and result interpretation, see the Data Evaluation document.
