The Java(TM) Client Sample Application follows a four-tier architecture.
They are:
- The client tier. This tier consists of Java clients
- The application presentation tier. This tier provides a bridge between
the client and the application logic tear, and manages the views of the Java Client
Sample Application.
- The application logic tier. This tier conducts business transactions.
- The backend system tier. This is the host which stores the business data.
The chart below shows the interactions among the first three
tiers.
