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

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

A little history
To understand what EAGLE does,
it would be helpful to understand
the problems it was originally
created to solve.
11. EAGLE
A little history
Once upon a time in the
swamplands of North Florida…
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…
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…
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 “screenscraping”.

A little history
Once upon a time in the
swamplands of North Florida…
At great expense, UF installed one of these
“screen-scraping” systems to provide students with
a Web interface to UF’s legacy CICS
resources.

A little history
Once upon a time in the
swamplands of North Florida…
The first public iteration of EAGLE delivered
student’s grades in the spring of 1998.
Soon after that initial success, nearly all student
registration functions were Web-enabled as
EAGLE-powered applications.
