I received assignment "Factory Homes" and started working on it.

If anybody already worked on this assginment kindly validate my understanding on Domain classes.

1. Customer has Completed Design(actually working design). Hope is persistable, we can have status as "In-progress" /"Completed"
2. each completed design consist of 1 or more Products. Here Products are configurable House Styles(reference data) which customer should select first to start the house design.
3. each product has one House
4. each house has one or more components(Foundation, Wall, Roof, Window, Door). Each wall has one or more Aperture. we can have "Component" as superclass for sub classes Foundation, Wall, Roof, Window and Door. we can have "Aperture" as interface so that Window and Door can implement it.

This is what i'm just thinking of domain classes and relationship. Kindly validate it.

There are some old threads on this forum that talks about the design of Factory Homes. You can look at my book too because the assignment with essay exam are well covered.

Here's the link: http://www.amazon.com/Oracle-Certified-Enterprise-Architect-Practice/dp/148254654X/ref=sr_1_2?ie=UTF8&qid=1361389883&sr=8-2&keywords=amritendu+de

That's fine. There isn't one distinct interpretation of the requirements.

Yes. Looks OK. I worked on Factory Homes. My analysis was something along those lines.
