Hi,

I am working on my SCEA II assignment. I have a couple of doubts.

BDM is technology independent and will represent the domain objects and their relationsips as prevalent in that domain. Assuming that there are two classes A and B that have 1 to many relaionship.

Doubt 1: When the BDM is translated into a Component diagram, which is technology dependent, the class A may have to be split up and implemented as a Business object (stateless bean), a DAO and a Value object i.e. one domain object may have to be split into 3 objects while implemented. Is this understanding correct?

Doubt 2: If my earlier understanding is correct, then only A's value object and B's value object will be having the 1 to many relationship and their business objects need not be related at all. Am i right?

If people who have cleared their SCEA can clarify, i would really appreciate it.

I think I did not understand the question at all but with my understanding if A and B are releated and has relationship, then no matter how you split that these two will have always some relation.

Anyway what ever be the actual scenario , I would suggest not to go in that much detail of showing the relationship at VO level.

Hi
I would suggest extending the entities in the Business domain object model rather than splitting or modifying it.
