Rules definition

There is a place in each transaction to specify rules to be triggered when the user interacts with the screen (to insert, modify or delete information).

Total length of videos: 12h

We see how to ensure that, in the Customer transaction:

no record is mace of a customer with empty name, empty surname, or a date in the system later than today (Error rule) a warning message is shown when the phone remains empty (Msg rule) the day’s data is automatically assigned to a Date attribute (Default rule) the edition of an attribute is disabled (Noaccept rule) We also see how to condition the triggering of a rule.

Specifically, in relation to the operation that is to be carried out: Insert, Update or Delete.

We show what variables are and what they are used for, and how we define variables in objects, as well as their main difference compared to attributes.
