Lot of annotations for O/R mapping.

While reading specs I found lot of annotations for O/R mapping, like @Inheritance, @Column, @JoinColumn, @PrimaryKeyJoinColumn, @Version, @Descriminator, @DescriminatorValue, and so many other annotations.

Do we need to learn all of them for the exam? However the Sun Objectives doesn't include many of them.

Yes I think, we should read all this annotation, and if possible we should practice as well. Since there may be some basic questions directly from these annotation in exam.

I think we should. If we don't know those Annotations, how do we implement systems using JPA?
