Here is some docs about setting up associations via the designer: http://www.mindscapehq.com/documentation/lightspeed/Creating-Domain-Models/Creating-Models-with-the-Visual-Designer I suspect you will either want a one-to-many association based on how you are describing the relationship above. Keep in mind that all associations are bi-direction so we dont have a "one-way" association as such but you can effectively generate what appears to be a one-way association by setting up a one to many association and then removing the "Collection Name" property from the association (Use a right click -> properties on the association line to find this) which will prevent the entity collection from being exposed on the one side.
