Agenda

Development Challenges• Skills Gap• Platform and Middleware• Existing Applications

The EGL Solution • What is EGL?• How does EGL solve the Development Challenges? • EGL Development Options• Migration Options• Value of EGL



Rational Focus on System i and z

New Organization formed in March 2006

• Headed by Hayden Lindsey, Distinguished Engineer and Director. Under auspices of Lee Nackman VP Development for Rational.

• Commitment to bringing existing Rational products to System i and z

• Commitment to identifying and resolving unique business systems issues for System i and z customers



IBM is Committed to Enterprise Generation Language

Key product in new System i and z organization

Large and expanding development team

New standalone product for business system developers

Major marketing initiatives• Sales, media, and market awareness

• Focused analyst awareness: Gartner, IDC, etc.



Business Systems Development – What do System i Customers Need?

WebSphere, SOA, Process modernization • Well received and recognized and needed

Customers need to improve aging systems • Better, safer maintenance, reduce production problems

• Improved response times for Business Systems Development

• Provide new user interfaces, B2B interfaces, and leverage emerging technology.



Platform & Middleware

Skills

Huge InvestmentThousands of lines of codeMust somehow co-existReuse, Re-write, Migrate …

Skills GapBusiness Oriented Developers lack Java and OO skillsVery Expensive to attain, very riskyLack of transferability of people across projects

The Challenge

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



Rational addresses the three key issues holding back IT modernization

Skills gap• Rapid adoption by business oriented

programmers

• Fast ROI Platforms & Middleware

• Cross-platform deployment

• SOA Existing Applications

• Migration/conversion/reuse of existing application components

• New (EGL) application development

Not only do we address them but we provide the most cost-effective solutions for each …



Skills Gap

New code cost 5X than reusing existing codeSoftware Productivity Research (SPR)

200 Billion lines of COBOL code in existence, eWeek

5 Billion lines of COBOL code added yearlyBill Ulrich, TSG Inc.

Between 850K and 1.3 Million COBOL developers with 12,000 per year attrition, IDC

Majority of customer data still on mainframes, even though a lot of it is front-ended through the Web

and e-Commerce applicationsDon Greb, Mellon Financial Corp from Computerworld

Rewriting existing applications & moving them to new platforms is not always viable considering …

But …..

Re-training COBOL developers to Java/J2EE costs over $50K each, and only 12% may actually succeed Gartner

Moving them into a productive business–oriented software development platform like RAD/EGL is a viable solution …

All callable from EGL

Make excellent EGL programmers

Easily accessed by EGL; all UIs supported



So Who are we retraining?

Business-Oriented Developers - they are Everywhere!!!!!

People who need to solve business problems quickly and efficiently • need higher productivity

• need to deploy to diverse platforms

• want to focus on business logic, not system plumbing or platform issues

They are 4GL and C/S developers• Software AG: Natural

• CA: Cool:Gen, IDEAL, Telon, Synon

• IBM: VAGen, CSP, Informix 4GL

• Oracle Forms, Visual Basic, PowerBuiler

• They are legacy developers• RPG, COBOL



A Case for SOA SOA is less expensive to maintain

• Developers don’t have to learn every new or proprietary technology

• Provides a cost-effective way to build, maintain and integrate application

SOA enables reuse• Business service are ‘exposed’ through standard interfaces making re-

use possible and beneficial SOA promotes business flexibility

• Reduces the time to create new applications

• Adapt to business requirements in a timely, effective manner

• Easier application integration; Services can be used by multiple apps and invoked by disparate clients

• No need to modify the apps code or database access when business requirements change

With EGL you don’t have to learn Java or Web Services to do SOA!



How does IT respond with existing applications? Rip & Replace

Replace legacy systems altogether (realistic?) and reduce in-house development staff

Buy commercial packaged software

Outsource

Rewrite legacy systems in-house (replicate needed function formerly handled by legacy, and add new business requirements) do you have the staff? Do they have the skills? How costly is it?

Leave & Leverage - Provides viable , cost-effective options

Modernization options

Migration

SOA

Develop new functions

In reality most companies deal with a mixture of these scenarios

In all cases the skills issue is huge



Why Are IT Shops Interested in Leave & Leverage Options?

Take advantage of new Market opportunities• Adapt business processes to align with new strategies

• Increase Business Agility Reduce overall Costs

• Legacy Software license fees are increasing

• Cost of legacy and 4GL skills are increasing & more difficult to find

• Lost business due to lack of application functionality

• Approximately 25-50% additional maintenance costs for legacy applications

Breathe new life into core business applications Reposition IT as ‘Business-Enablers’

Learning & Adoption Problem Java for business developers:

6 months training,

2 years to proficiency!

“Re-training COBOL developers to Java/J2EE costs over $50K each, and only 12% may actually succeed” – Gartner Group

“The task force had an initial meeting and identified challenges to teaching Java based on the literature and our experiences.” – ACM Education Board Java Task Force http://www.sigcse.org/topics/javataskforce/

An insurance company spent approximately $250,000 to train 12 RPG developers. One out of 12 succeeded. This person had a MS in Computer Science and 8 years of C programming experience. – Bob Cancilla



Java without the Java?

EGL is a combination of high level language and advanced Eclipse based development tools.

EGL can be learned by anyone with a basic understanding of programming in any language.

can be learned in 1 week – expert in a month.



What is Enterprise Generation Language (EGL)?

A simple high-level language• Programmers will easily learn EGL

Code Generation, but not a 4GL• EGL is the culmination of 25 years of experience in Code

Generation from CSP to VisualAge Generator to EGL!

• Generates Java and COBOL

Complete application development environment• Build core business applications, not just UI

• Full SOA support!

Hides the Technology• Example is MQ Series: get queueName, put queueName
