The DWP® Architecture

Extensive measurements revealed that traditional Progress© architectures suffer from three major bottlenecks when faced with internet deployment: too many AppServer calls, excessive data exchange, and large r-code deployment to the client.

The DWP Architecture is based on the union of a single ¨Business Logic¨ object on the server and a single ¨User Interface¨ object on the client. Together, these two objects are capable of delivering full-blown Windows applications to the end user with sub-second response times over dial-up internet connections.

The use of bandwidth is typically much lower than a comparable HTML-based web application. A single user interaction results in just a single AppServer call, even if that interaction returns a screen full of browser and viewer data. Due to the stateless architecture a single application server can support thousands of concurrent users.

As a matter of fact, with the DWP Architecture you do not have to wait for UMTS frequencies to become available to provide wireless access to your applications; a standard GPRS connection is sufficient to run DWA applications on your laptop. Even a 9.600 baud GSM connection can be used to access DWA applications from anywhere in the world. This claim leaves the major industry players out in the cold.
