I have the following scenario in mind:
I have DB, app server and gui client, each on individual machine. Client can talk to app server via http, app server can talk to DB. 1. client call GetCustomers on app server 2. app server goes to DB (only app server has access to DB 3. app server returns dataset, array or collection of customers to client 4. client modifies collection, adds new customer, or modifies some customer 5. client calls UpdateCustomers on app server 6. app server goes to DB and updates The key point is that client doesn't have access to DB. I could create two classes, Customer < SequelModel and CustomerNTier, and copy variables between them. I couldn't pass Customer directly to client, since client doesn't have access to DB and all updates must go through app server.
