lder interface systems such as those using COBOL on IBM AIX, or RPG on IBM i are expensive to replace and often difficult to integrate. See how to quickly leverage these systems in an environment without rewriting or having access to the original source code. Using IBM Rational Host Access Transformation Services (HATS), create REST-based or SOAP-based Web services to call from other systems. Presenters demonstrate a customer solution that was originally written in COBOL on AIX that now uses HATS Web services. Presenters show how using the new Dojo features in HATS, teams can rapidly build a new interface without rip and replace of the old system. HATS and Dojo help dramatically reduce data entry errors, improve customer call times, and make it easier to train personnel to use the applications. The session includes demos.

Why modernize my green screen?
 “If it ain’t broke…”
 “Only our call center uses it. … “
 “It’s a 3rd party app”
 “I’ve used it for 20 years.. Nothing wrong with it!”
 “We don’t need to integrate it”
 “Too much invested in it to throw it away”
 “But it has all our business rules!”
 “We’re going to all .NET …..next month”
 “We spent too much training everyone on this
system”
 “Joey retired and we lost his member files”
 “I’m retiring next year, what do I care?”

Business Challenge: Data Entry Errors
 Terminal Apps offer poor data entry controls
 Garbage in – garbage out
 Poor data entry results in:
– Inaccurate business intelligence
– Giving the customer or patient the wrong order
– Longer call times
– Loss of productivity due to data re-entry, or data correction
– Having to purchase additional software to correct errors (i.e. Infosphere QualityStage, Optim, etc)

5. The Premier Event for Software and Systems Innovation
Business Challenge: Longer Training Time
 Non-intuitive interface
– No tool tips, context sensitive help, coded fields, abbreviations, etc.
 Current generation knows the web
– Does NOT understand ‘field exit’, ‘clear’, etc.
– “Where is the PF3 key?”
 Training is often a neglected item in IT budgets
– Isn’t that what consultants are for?
 Average annual turn over in a call center is 33%*
– Longer training required == less productivity, greater cost per resource

Business Challenge: Lack of Access to Source Code
Columns . . . .: Edit
SEU ___________________________________________________________
-----------------------------------------------------------------
Common with COTS applications
Legacy apps from acquisitions
Required use of a partner, vendor, or parent company application
Developer lock out
– You fired the guy who had the code, he deleted it as he walked out
Changes to source may involve costly risks
– “Everything is tied to our ERP!!”

Lessons learned, recommendations, tips and techniques, etc.
 Develop your HATS apps iteratively
– Don’t spend 6 months waiting on the big bang
– Gather feedback with each iteration
– JPA 2.0 and WAS 8.0 makes RDBMS integration simple
 Version your assets
– HATS apps are Java EE apps
– A file system does NOT make a version control system
 You don’t have to, but you CAN do very complex things with HATS
– Business Logic is Java, and at the heart of how HATS and HOD work
– Macros have their own language elements
– Custom widgets/components can make your site unique
 Utilize a designer to help you with UI for maximum benefit
– The latest HATS templates are very good
– Dojo Widgets greatly simplify client side validation and data entry
– Custom branding needs a designer
