Tuto WINDEV 25

Part 3: My first database 113 We are now going to modify the relation file that was created by WINDEV. Indeed, this relation file will contain the order lines. We are going to: • Modify the name of the data file. • Modify the name of its items. • Add items to find out the quantity of products ordered and the total of order line. ▶ First, we are going to rename the data file. We already did something similar when we changed the caption of the imported data file. However, in this case, not only the caption will be modified: we will also rename the physical file linked to the data file description. 1. Select the "Product_Orders" data file. 2.  In the popup menu (right mouse click), select "Description of data file".
