Key Messages
Businesses need to change to stay viable, and IT must enable this flexibility.
IT’s role is to enable the business!
IT must overcome challenges:
 Reuse & leverage core systems
 Understanding the inventory of current IT assets
 Complex, tightly coupled architectures
 IT Skills lock-in
 Islands of development
 No flexibility for new investments
 High Cost of Maintenance
The IBM Rational Software Delivery Platform helps companies overcome these
challenges and facilitate Enterprise Application Transformation & modernization.

What is Application Transformation?
A Migration strategy/approach that utilizes (reuses) existing legacy
application assets while targeting a more modern, flexible, and
cost-effective software development platform
These applications are:
Core business systems, critical to operations
Tested, Proven and Production-ready
Have consumed enormous amounts of
Time & Treasure to develop and in many
instances to maintain

What Application Transformation Must Address
Huge Investment
Skills Gap
Financial (Treasure), Time & Effort
 Thousands/Millions of lines of code
Business Oriented Developers lack
Java and OO skills - very expensive to
attain, very risky
Lack of transferability of people&
skills across projects
Proven, tested, in production
applications
Core to running the
business
Platforms & Middleware
 Ability to support and target the broadest variety of platforms and middleware
 e.g. Mergers/acquisitions, right/down/up size, QoS requirements, strategic redirections,
SOA, On-Demand etc.
A comprehensive approach to Enterprise Application Transformation & Modernization.

Why Transform to RBD (EGL)?
 Fastest, most cost-effective migration path off legacy code
 Leverage your huge investment - Time & Treasure
 Reuse of existing, mission-critical, production tested software assets
 Establish a Modern, More Flexible Development Platform
 Design and Develop the widest rage of applications possible with a single,
integrated software development platform
 Exploit a more cost-effective development environment
 The Rational SDP is a fraction of the cost of most legacy environments
 Maximize on the existing in-house IT skills & domain expertise
 No need for outside hiring or extensive, expensive training

Why Use EGL as the Target?
 It is the “GLUE” that allows app transformation to happen smoothly
 DNA (Discovery aNd Analysis) and Transformation Process is Highly
Automated
 95%-100%
 Mapping between EGL and 4GLs, COBOL and RPG is Excellent!
 Source Code (EGL) produced is easy to Read and highly Maintainable
 JumpStarts EGL Application Development
 Low learning curve for most 3GL & 4GL programmers (weeks)
 Supports Open Standards
 Direction - Open & Extensible EGL Community
 PROVIDES A VIABLE BUSINESS PATH OFF LEGACY DEVELOPMENT

 Project Management - like any IT project you
must keep the project on track, stay on task,
meet milestones and move rapidly to production
 Addressing Code Remediation (as required)
 Data Base conversion
 Batch processing
– e.g. JCL
 UI issues
– TUI, Web (JSF), RUI
 Messaging issues
 Adequate Testing (Unit, Systems, Performance,
Acceptance, User ..)
 Retraining (Retaining) of IT staff (and possibly users)
 Customer (in-house) IT role in all of the above

 Core strategy for modernizing 7000 System z and 200,000 System i customers
 Part of System i Marketing materials
 IBM’s only enterprise class “cross platform” e2e solution
 Under Industry Standardization process (OMG)
 RBD V7.1 is one of the designated key products for Rational in 2008 (RBD v7.5 fall 2008)
 Additional Marketing efforts
 Additional Resources (technical and sales)
 Large IBM install base of stabilized legacy 4GL
 CSP, VisualGen, VisualAge Generator Customers (over 3,000)
 Natural/ADABAS, CA Cool:Gen, Maestro, COBOL, RPG …………
 Include very large and critical IBM accounts with significant investment
 Strategic Migration path for legacy application development

Summary

Enterprise Application Transformation is not trivial, but with the right
amount of Time, Treasure and Automation it is a Viable, Cost-Effective
approach for modernizing aging application technologies




Preserve your huge investment in these systems
Maintain the full functionality of these systems
Replace the part of the system that “inhibits”
Allows for Reuse of proven functionality extracted from tested,
production-ready systems
 Enables the Redeployment of business-critical, stable functionality as
Services (SOA)

Rational Business Developer (EGL) makes this possible
 High level of language compatibility, readability and maintainability of
converted code
 Provides maximum deployment flexibility and use of IT resources with
Maximum Leverage of existing IT staff with minimal training expense

More cost-effective than Replacement or Rewrite options

Why Use RBD (EGL) as the Target?
 What is Enterprise Generation Language?
Rational Business Developer (RBD) is the component of the IBM Rational
Software Delivery Platform that’s specifically designed to fulfill the needs of
business-oriented developers. The product provides a comprehensive
Eclipse-based development workbench for IBM Rational Enterprise
Generation Language (EGL) - a powerful, easy-to learn and highly
productive modern language that equips developers of almost any
background with a simplified and more abstract development paradigm
that allows them to quickly deliver cross-platform, transactional datacentric services and applications. As a business programming language,
EGL is designed to let you write full-function applications quickly and
independently from the target run-time platform, freeing you to focus on
business problems rather than complex software technologies
