# Develop data set class

Use a data set on a form control of type Data grid. The data set gets the data to be shown in the data grid.

For a data set, a class is required. To develop this class, extend the DAWQueryMethodRun class.

**Prerequisite**: Develop the extension of the DAWQueryMethodRun class in the AOT before you start the steps.
