>Hi,

>I have a Clients table and a Policies table. A client can have one or many policies. When displaying a single Policy I want to display some of the client details like Name and Number. Should I set Client as a child business object of Policy, or should I include the related fields in the Policy entity?

If you have required relations set in database then when you use the EF designer it adds the navigational properties and you would simpky say for example:

Policy oPolicy = db.Policies.Single( p => p.Id == policyId );
Client c = oPolicy.Client;

or the other way:

Client c = db.Clients.Single( c =>c.Id clientId);
foreach(var policy in c.Policies) {//...}

Update: Discard. I din't notice it was mm section.
