Why does JPA have a @Transient annotation?

Question

Java has the transientkeyword. Why does JPA have @Transient instead of simply using the already existing java keyword?

Answer 1

Java's temporary keyword is used to indicate that a field is not to be serialized, whereas JPA's @Transient explanation is used to indicate that a field is not to be persisted in the database, i.e. their interpretation are different.
