Hi Tarun;
Large to-many can be trouble for the reason that you have identified. I
tend to omit those from the model, leaving the to-one relationship in
place. EOF allows this because the relationships are not automatically
reflexive.
In this I mean that the to-one and to-many relationships are modelled
separately and you can just remove the to-many one for the large
relationship.
cheers.

So I've got a situation where I'm seeing a SELECT that will eventually
kill my performance and want to see if I can fix it before my site goes
live.
My EOModel has an object called a Landing and an object called a
SiteDefinition. The SiteDefinition defines what the site looks like and
the Landing represents a user landing on the site. When a user comes to
the site, I create a Landing and associate it with the SiteDefinition so
that I can capture what site a user sees and what users were on a site.
SiteDefinition to many Landings
When I add the relationship using this:
aLanding.setSiteDefinitionRelationship(getSiteDefinition());
WebObjects decides it needs to select all Landings where the
siteDefinitionID equals the one I'm assigning. This is fine in dev where
I may only have 17 records but eventually I may have 10s of thousands of
records.
Is this my EOModel, and if so how can I prevent it?
Thank you,
Tarun
