Field names in databases are often difficult to interpret. Using user-friendly names enables you to understand the field’s contents more easily. For example we are unable to tell from the expression Name whether the expression refers to a customer name or salesman name. Changing the expression: Name to Customer Name makes the expression less ambiguous.

1. Click on the data expression to be renamed.

2. Click in the Expression Name box in your properties windows, right hand side of the screen (smaller arrow below). Enter text “Customer Name” and click Apply (larger arrow below.)

3.  The new name is displayed.
