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.
