[Seaside] generating relationships

[sergio_101]

i just got through with the gemstone tutorial (http://seaside.gemstone.com/tutorial.html 
).. a really great tutorial on some of the facets of seaside..

one question i do have is:

if i have some objects like:

artist
album
fan

where an artist has many fans
an album belongs to an artist
an artist can have many fans
a fan can have many artists

how do i articulate those relationships?

how would i articulate something like..

give me a list of all fans of a specified artist..
give me all albums from this artist..

thanks!
