As we saw in the last section, there are two ways to embed a data object into an Impress presentation. To create a new data object or to embed an existing file as a data object. To edit or delete embedded data for a newly created data object, we simply need to double-click on the data object. This will bring the data object into its native form. This means that if the data object was a spreadsheet it will start looking like a spreadsheet.
After this, edit or delete the data in the data object as is normally done. When you next save the presentation, your changes will get saved.
Though the same does not apply to a data object created from an existing file. To edit or delete a data object which has been created from an existing file, you need to edit the original file.
After making changes to the original file, when the Impress Presentation will be next saved, the changes will get reflected in the data object.
