Progressive Aviation is a thin client
solution: Ideal for providing a feature-rich, graphical user
the internet, an intranet or a LAN.
The thin N-tier client
system has been widely proclaimed as the architecture of the present
and future. So why are there still so many two-tier, client
server applications out there? Perhaps client server persists
because it remains an effective and familiar model for many back office
standalone applications in corporations. But it can no longer be
denied that two-tier implementations that have become competitively or
technologically restrictive often now linger within organizations,
robbing them of the benefits of more up-to-date applications.
With the thin client, you will realize the following business
information assets. User interfaces
come and go (character, Windows, HTML). But the main investment
is in the business logic which on the thin client architecture is
separated from the user interface. The business logic in contrast
to the user interface is not likely to change a lot. New
interfaces can be added as technology changes, preserving the base
investment in the enterprise software.
maintenance costs. Updates
to client server applications often require IT staff to make time
consuming (and costly) changes at every client workstation. In a
three-tier architecture, users of web clients automatically receive
software updates at user login as needed.
Lower cost of
ownership. When application logic
is centralized (and separated from client side user interface), as in
an n-tier architecture, organizations can distribute processing power,
storage and memory more cost effectively. Organizations
achieve this user friendly graphical functionality without the cost and
maintenance of a Citrix server.
performance. The AppServer
lets you partition applications across a networked enterprise, so you
no longer have a performance bottleneck at a single client or server
machine. To further refine performance and scalability, Progressive
Aviation uses stateless server technology. Using stateless
technology, an AppServer process is no longer needed for each
user. Ultimately, you benefit from a corresponding reduction in
overall hardware requirements and user licenses.
user interfaces (Character, Windows,
HTML) are separated from business logic, so can put any user interface,
