Incapsulano la logica dell’applicazione
Business Rule
CLIENT
[CustomerAgent, SupplierAgent]
Lavorano a nome dell’utente
Assistono l’utente nel lavoro
SERVER
[RequisitionAgent, DeliveryAgent , InvoiceAgent]
Soddisfano le richieste di altri agenti
Per fare ciò:
Interagiscono con altri agenti server
Manipolano server object
Agenti l’architettura
