Hi All,

I am working on Factory Homes Assignment. I am dealing with the following architectural decision:

1)Do we need to persist in the Factory Homes DB the components that the user have selected to create the house? I would want to avoid it because this will mean to replicate the same entities/tables (wall, roof, ....) aleady present in InventorySystem.

Since that the Factory Homes is owner of the InventorySystem, I think that an alternative could be store directly in InvetorySystem the components that are seleced from the user and wtht an external key we could retrive it in Factory Homes the components that compose a copleted design.

What do you think of this?

Thanks in advance,
Mimmo

Mimmo,
As I recall, you aren't designing the Inventory system. I wouldn't assume you can refer to it because I think it oversimplifies the problem.

Hi Jeanne,

you are right that we are not designing the inventory system, but if what I asked/thought could be right then I will put it in the list of the assumptions. Because when you are designing a system that need to interact with external system, that are maintained from the same company, then it could be reasonable to require some small modifications to the external system

I am working on it too. Well in my understanding Inventory System is to be considered "immutable". A black box used only for what it is described in the spec.
However, due to my past works and experience, I was thinking to get rid of a DB by using a CMIS enabled ECM, such as Alfresco, Share Point etc. This way I could store and retrieve the XML, and all rendered stuff (video, jpg, etc..).
