one-to-one help

I am new to hibernate and trying my hand on it. This may sound a very basic query but i could not get it reading the docs.

I have two tables:

ARTICLE: which has certain number of fields with
articleCode as the primary key and other information like
description, life time, etc
It also has a brandCode which is a primary key of another table called
BRAND which stores information about brand like description, etc

In my Article object which is mapped to the Article table, i have one more property called brand description which i have to pick from the brand table depending on the brandCode that i have in the Article object. It is a straighforwar one-to one mapping between Article and Brand.

I need only a text field from the brand table (description) in the Article object. What mapping should i use and how do I retrieve the data most efficiently.

Thanking in anticipation,

You cannot (yet) map an object into several tables.

So map article -> brand in a many-to-one way and add a unmapped getter on the description

Code:

public String getBrandDescription() {
  return getBrand().getDescription();
}
