Thanks K. Tsang appreciate your kind and quick responses!
Another question in component diagram I have layer like this:
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 ?
In deployment diagram :
If I want to put firewall router should I put it before or after load balancer?
