How does ORMLite store ForeignCollections in the database?

I have two classes, User and Artwork. User can have a collection of Artworks. Everything works as expected, I can store and retrieve the objects from the db, but I don,t understand how they collection is persisted.

public class User {



    @DatabaseField(allowGeneratedIdInsert = true, generatedId = true, unique = true)

    Long id;



    @DatabaseField

    String name;



    @DatabaseField(columnName = "artwork_id", foreign = true, foreignAutoCreate = true, foreignAutoRefresh = true)

    Artwork masterPiece;



    @ForeignCollectionField(eager = true)

    Collection<Artwork> artworks;

} 



public class Artwork {



    @DatabaseField(allowGeneratedIdInsert = true, generatedId = true, unique = true)

    Long id;



    @DatabaseField

    String name;



    @DatabaseField

    String file;



    @DatabaseField(columnName = "user_id", foreign = true, foreignAutoCreate = true, foreignAutoRefresh = true)

    User owner;

}

I create some artworks, add them to the collection and set the collection in the a User. When checking the .db (.schema) I get this:

CREATE TABLE android_metadata (locale TEXT);

CREATE TABLE `user` (`id` INTEGER PRIMARY KEY AUTOINCREMENT , `name` VARCHAR , `artwork_id` BIGINT );

CREATE TABLE `artwork` (`id` INTEGER PRIMARY KEY AUTOINCREMENT , `name` VARCHAR , `file` VARCHAR , `user_id` BIGINT );

Objects are being correctly inserted and querying for them works like charm. What I really don't understand is why I there is no field for the collection.
