Eagle (Mainframe Application Server) : ウィキペディア英語版 | Eagle (Mainframe Application Server)
EAGLE is a Web-based, mainframe-powered application server which provides direct, secure, high performance Internet access to mainframe computer data and transactions using real-time transaction processing rather than middleware or external gateways. Originally based in an IBM 3270 environment developed at the University of Florida to reduce the delivery time of student record applications, the engine was configured for the Web in 1996 and removed the need for a screen scraping interface. ==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. 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 resulting 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.
