Release 10.1A: OpenEdge Getting Started:
WebSpeed Essentials

Introducing WebSpeed

WebSpeed® is a Progress® 4GL development and deployment environment. WebSpeed allows you to build applications that use HTML, XML, WML, DHTML, and most other mark-up languages (MLs) as the user interface. This means that WebSpeed can be used for applications where users are accessing the application using:

A Web browser (HTML, DHTML, or XML).
A mobile/cell-phone (HTML, WML).
A system making requests for information using XML and HTTP or HTTP/S as the transport protocol.

In addition to building Web-based applications by design, you can use WebSpeed to Web-enable existing OpenEdge applications that previously ran stand-alone or as a Progress AppServer™-based application.

With WebSpeed, you can develop and deploy:

Intranet applications that allow internal users to access and modify data.
Internet applications that allow external, consumer access (for example, a shopping cart application).
Extranet, business-to-business applications.
