I am confused on where the DAOs and Adapters belong to, whether to Business tier or Integration tier? In my design, DAOs are used for searches, Adapters are used for connecting to subsystems. Both are fronted by session beans.
But both integration tier and business tier run on the same machine. I mean, the DAO's as well as the Session beans run on the same application server. Is it then still usefull to make the difference on the component diagram ? Or is it just to make the 'logical' difference..
And, what about entity beans ? They belong too in the integration tier, no ?
But both integration tier and business tier run on the same machine
Who told you they can't be on same machine?
As far as SCEA point of view In the exam there are 2 different servers(Web Server) and (App Server) because exam started in the era when both servers were coming seperately. But in today's scenario there is nothing like that. And even though in the case of different AppServer both tiers on same machine. [ December 29, 2005: Message edited by: Jignesh Patel ]
