Another question in component diagram I have layer like this:
Presentation->Business->Persistance->Integration->External System
My question is
a)Can I show manger form business layer using persistance entities and then also dao to contact external system like email,ldap etc?
as well as
b)business manager access dao thorough entities or directly manager connecting dao by passing persistance tier
Not sure if I can mix and match from architecture perspective ?
It depends on what you like. When I did mine, I didn't have a persistence tier per se. I had my entities in the business tier. The DAO in the integration tier.
If you have a persistence tier, those entities should be in this tier.
As for the 2nd question, business manager will need to use entity classes and DAO classes. I doubt you can omit the "use" line from manager to entity because the entity usually the return type.
