What is a Persistable entity? ANSWER: ✔- An Entity that can be saved in
the database.
What is a Non-Persistable entity? ANSWER: ✔- An entity that can only be
saved in runtime memory.
What is a Generalized entity? ANSWER: ✔- An entity that lends its
attributes, associations, event handlers, validation rules and any other
properties to another entity.
What is a Specialized entity? ANSWER: ✔- An entity that inherits all or part
of its attributes, associations, event handlers, validation rules and any other

How do you show multiple specialized entities in the same list view?
ANSWER: ✔- By adding a template for every specialized entity while using the
default for the generalized entity.
What do you need to do after an Object type decision? ANSWER: ✔- Cast
to entity to the correct specialization.
What should you do if the Object type decision is empty? ANSWER: ✔-
Create a log message, since this is unexpected behavior.
Why should you use inheritence? ANSWER: ✔- It allows you to make
reusable microflow, which increases the consistency and maintainability of
your app.
when should you use a 1-1 association over inheritance? ANSWER: ✔-
when the entity in question isn't a true specialization of the generalized entity
, ASCORERS STUVIA
and/or the generalized entity's properties are not required when dealing with
the entity in question.
Why is creating a new entity and making it a specialization of the FileDocument
or Image entity preferred over using original entities? ANSWER: ✔- The
