Data Connection Dataset

A data connection dataset refers to creating a dataset using a data connection as the data source. You can set filter conditions to perform row-level selection, processing, and filtering operations on the data, selecting the necessary data. The filtering function supports simple filtering and expression-based filtering.

Create Dataset

Follow the steps below to create a data connection dataset.

1. In the dataset interface, click "New Dataset" and select a data connection.

2. Choose the data connection to be used for creating the dataset.

   If the desired data connection is not found, you need to contact the data administrator to authorize the required data connection before use.

3. Edit the dataset content. You can define dataset conditions through filtering criteria to filter the dataset content. Both simple filtering and expression filtering are supported.

   • Simple Filtering: Users set filtering conditions through options. When there are multiple filtering conditions, you can set the condition selection method as 'All Conditions' or 'Any Condition'. 'All Conditions' means the filtered data must meet all the filtering conditions. 'Any Condition' means the filtered data only needs to meet one of the conditions.
   • Expression Filtering: Users set filtering conditions through expressions, allowing for more flexible data filtering. The filtering expression must return a boolean value. On the right side of the expression editing area is a list of functions for use in the expression.

   Tip

   You must preview the data after writing the filtering conditions before proceeding to the next step.

4. Click "Next" to enter the data structure configuration page, where you can select fields, set field aliases, and types.

   Tip

   1. Fields that are unchecked will be stored in the dataset in a hidden form, and users can display them when needed.
   2. Support for enabling the acceleration engine is available, which imports the dataset into the acceleration engine.

5. After clicking "Import," edit the dataset name to complete the dataset creation. You can view the dataset in the dataset page and perform operations related to dataset management.
