What Happened! How Did We Get In The Red?

Business and competitive landscapes change, surpassing application capabilities

Product Invented Spread

Electricity 1873 46

PC 1975 16

Cell 1983 13

Internet 1991 7

Technologies change, outpacing older ones


How Bad Is It?

Is the application increasingly costly to enhance and support?Is the time and effort needed to customize the application for new

requirements affecting the ability to keep up with the business?Do architectural or design limitations hinder the addition of desired

new functions that would increase the application’s value or marketability?

Carl BrewerPresident, Integrated Warehousing Solutions

“IRMS Warehouse Management System was beginning to show it’s age”

“Needed to provide significant advantages to support emerging opportunities and market demand for Supply Chain Visibility solutions”

“FY2005 sales of IRMS increased 28%, and early FY2006 results clearly indicate that sales could easily exceed 30% above projected numbers”


Can a New Application Architecture Help?

YES! New design patterns… Distributed applications… Latest technology and tools…

…all lead to Service-Oriented Architecture (SOA)…


Is It Just Us?

“By 2008, SOA will be a prevailing software-

engineering practice, ending the 40-year

domination of monolithic software architecture”-- Gartner Research

“An increasingly common strategy for mid-scale

applications is to leave the Cobol in place while

using a service-oriented architecture (SOA) to

expose key interfaces that insulate developers

from the code. ”-- “Rebuilding the Legacy – Modernizing Mainframe Code”ComputerWorld, April 24, 2006


SOA

A service-oriented architecture (SOA) is the underlying structure supporting communications between services. A service is a unit of work to be performed on behalf of some computing entity, such as a human user or another program. SOA defines how two computing entities, such as programs, interact in such a way as to enable one entity to perform a unit of work on behalf of another entity. Service interactions are defined using a description language. Each interaction is self-contained and loosely coupled, so that each interaction is independent of any other interaction.


Now, I Know What You’re Thinking But…


SOA Is Here - Are You Ready for IT?

SOA-1 Fundamentals of Service-Oriented Architecture

ServiceOrientedArchitecture



Loosely coupled applications will impact IT organizations

ServiceServices: Represent logical groupings of operations provided by an application. If ItemProfiling is a service, then, Lookup Item by item number, List Item by name and item number, and Save data for new items represent the associated operations.



Loosely coupled applications will impact IT organizations

Oriented: to place in the right position; bring into the right relationship with the architecture.

Oriented



Without a focus on architecture, your SOA may be DOA

Architecture: The overall structure, logical components, and the logical interrelationships of a computer, its operating system, a network, or application oriented towards providing services.

We Can Help!OpenEdge 10

OpenEdge Architect• a set of tools for developing business process-centric

applications with OpenEdge

ProDataSets• ProDataSets allow data to

be manipulated as an object. Now bus ready with to/from XML conversion!

Object-Oriented Extensions to the ABL.• Helps developers better

manipulate objects in a SOA


We Can Help!OpenEdge 10

XML and Web Services• XML is the standard protocol for the Service Bus. OE10

supports SAX, making communication more saxxy!• Your applications can easily use the web services standards

OpenEdge Adapters for Sonic ESB• Your objects are now native services on the #1 bus!

Pitfalls

False presumptions about understanding of the legacy system

Direct Database Access

Modernization process is different than standard development

Shared Variable instead of parameters (good) or ProDataSets (best!)

Few resources, balancing with new requirements

Legacy Design of Process Management

Outdated training Application Data Management

No long term commitmentOlder Design of Transaction Management

Organizational Inhibitors Technical Gotchas!


How About Some Positives!Some Stuff I Can Do Now!

Identify & Understand• Code that can be transformed quickly

Harvest• Logic which is independent of user interaction

• Logic which is used many times in the application

Transform• Encapsulate direct database access, eliminate shared resources from the client• Create individual procedures, or Business Entities, based upon distinct process logic

functions

The Guide





It’s Not about Technology

Over 80 Progress customers worldwide going through transformation

Progress services can help…• Identify & Understand - application and staff

• Harvest - capture old & reuse, define new

• Transform – Mentoring on architecture and skills. Use of existing tools and methodologies

Competitive Advantage is Not Built by Technology,It’s Built by People


In Summary

Identify & Understand• Transformation is achievable

and can be evolutionary Harvest

• You can retain and reuse valuable investment

Transform!• Help is out there and many

organizations have gone through the process
