We have created the default value for the atribute whose value is determined at runime,
using Groovy expression. This means that whenever we create a new record for the EMP table
through EmpEO , If job is MANAGER , the Sal atribute is defaulted to 1000 ; otherwise the Sal
atribute is defaulted to 2000 . We will have a dependency set for the Sal atribute on job ;
this means whenever the value of job changes, the value of the Sal atribute is recalculated.
