Presentation summary 1. What is EAGLE? 2. A little history 3. What EAGLE does now 4. A simple EAGLE page 5. The future of EAGLE 6. Discussion 7. Conclusion EAGLE

What is eagle? EAGLE is a set of CICS programs that provides a TCP-enabled application, development, control, and communications environment. EAGLE

What is eagle? IBM’s CICS * is the world’s most reliable, robust, and speedy customer information system. EAGLE

What is eagle? However, CICS is primarily a mainframe application and has inherited some communications interface issues: EAGLE

What is eagle? It was never designed to talk via any interface except SNA. EAGLE

What is eagle? It was never designed to talk via any interface except SNA. Data access was often tightly linked to display logic. EAGLE

What is eagle? In short, while CICS provides fast, robust access to data, this access has been restricted by a simplistic, antiquated interface. EAGLE

A little history To understand what EAGLE does, it would be helpful to understand the problems it was originally created to solve. EAGLE

A little history Once upon a time in the swamplands of North Florida… EAGLE

A little history Once upon a time in the swamplands of North Florida… EAGLE UF is the state's oldest, largest and most comprehensive university. With more than 46,500 students, UF is among the five largest universities in the nation.

A little history Once upon a time in the swamplands of North Florida… EAGLE In the middle 1990s, the popularity of the World Wide Web made the Web browser an ideal method for students to access their registration functions and information.

A little history Once upon a time in the swamplands of North Florida… EAGLE However, access methods had not kept pace with the exponential growth of the Internet. The only practical way to provide Web interaction with CICS data at this time was via “screen- scraping”.

A little history EAGLE SNA 3270 (“Dumb Terminal”) OS/390

A little history EAGLE TCP client (WWW, e.g) OS/390 AgentSoftware(Middleware) Webserver TCP NT or UNIX or OS/2 SNA TCP

A little history Once upon a time in the swamplands of North Florida… EAGLE At great expense, UF installed one of these “screen-scraping” systems to provide students with a Web interface to UF’s legacy CICS resources. It was… less than successful. However, the lessons learned in the process of implementation proved invaluable in developing EAGLE later on.

A little history Once upon a time in the swamplands of North Florida… EAGLE The first public iteration of EAGLE delivered student’s grades in the spring of Soon after that initial success, nearly all student registration functions were Web-enabled as EAGLE-powered applications.

What eagle does now EAGLE method EAGLE TCP client (WWW, e.g) OS/390 Webserver (more) EAGLE CICS TCPTCP

What eagle does now EAGLE method EAGLE OS/390 Fast– uses much fewer resources than screen-scraping Flexible– extends functionality into any TCP-enabled architecture (more) EAGLE CICS

What eagle does now EAGLE method EAGLE OS/390 Stable– billions of pages have been delivered in production applications Secure– uses existing authentication / authorization (more) EAGLE CICS

What eagle does now EAGLE method EAGLE OS/390 Powerful– intuitive Web GUI helps cut development time Scalable– architecture allows increase in system power without creating “server farms” (more) EAGLE CICS

What eagle does now EAGLE EAGLE includes powerful application development tools:

A simple EAGLE page How do I create a page in EAGLE? EAGLE

A simple EAGLE page How do I create a page in EAGLE? The core object in EAGLE is the Page Definition. EAGLE

A simple EAGLE page How do I create a page in EAGLE? The Page Definition defines  the name of the page  where dynamic data (if any) lives  what programs (if any) are invoked EAGLE

A simple EAGLE page How do I create a page in EAGLE? When you create an Page Definition, you have created an EAGLE page… but there is nothing on it! EAGLE

A simple EAGLE page How do I create a page in EAGLE? Text is placed on an EAGLE page in one of two ways: EAGLE

A simple EAGLE page How do I create a page in EAGLE? Text is placed on an EAGLE page in one of two ways: Static data is placed on the Layout page… EAGLE
