What EAGLE does

EAGLE provides direct network access to mainframe data and transactions. Web applications talk directly to native mainframe resources without the complexity or expense of middleware. Non-mainframe resources can be accessed via hooks to customized communication programs, using XML or EDI. The Extensible Markup Language (XML) is a general-purpose markup language. ... Electronic Data Interchange (EDI) is a set of standards for structuring information to be electronically exchanged between and within businesses, organizations, government entities and other groups. ...

Since EAGLE is itself a mainframe computer transaction, application pages are created internally and delivered via the Web. This reduces overhead compared to external call interfaces and has resulted in considerable performance gains; during periods of peak demand at the University of Florida, EAGLE routinely handles 400,000 transactions per day while maintaining sub-second response time.

Session management

The Web is defined as a stateless environment-- normally, a Web page is requested, the Web page is delivered, and the interaction is over. EAGLE associates pages with a user and handles authentication and authorization. The EAGLE session management engine is protected behind mainframe security. The term stateless can mean more than one thing: In law, a stateless person is a person without a state, in other words someone who is not a citizen or subject of any state. ...
