Today's Goals

• How can your current Application code play a role
  in a Service Oriented Architecture

3
Today's Goals

• How to expose existing 4GL code to non Progress
  technologies

4
Today's Goals

• How to use this 4GL code as an integration service

5
Agenda

• Business Today
• The Industry Evolution
• OpenEdge Architecture
• Episode 1 AppServer
• Integration
• Episode 2 Sonic ESB

Application Problems
my confession

• Growth is limited
• And very expensive
• If load shifts, people take the hit
• One single entrance point into BL
• I have no clue about integration !!!

8
Customer Needs
.NET, Java, XML, Web services, Lets see how
they cope with that

• Expand business
• E-business functionality
• New Devices!
• Minimize human errors
• Maintain current hardware
• Integrate with legacy application
• Low maintenance costs

9
Developer Needs
Ooooh How will we cope with all that

• Time-to-market - ROI
• Platform independency
• Fashionable UIs
• No rewrite every x years
• Open to future technologies
• Integration possibilities
• Focus on functionality vs technical
  infrastructure

10
Industry Rules

• Service-Oriented Architecture
• Web services
• Shift to self-servicing
• Real-time enterprise
• Use MOM, XML, SOAP!
• ESB - integrating core business processes to
  anyone, anywhere
• .NET, J2EE

11
Our Opinion?
The Worlds Best Applications

• Will not be bound
• by any one user interface technology,
  methodology, or platform
• Cannot exist
• as an island, Interoperability, central to the
  design and integration, must be easy
• Will be
• business processes expressed as software

The one where we impress the audience by
showing them that by moving to a SOA, multiple
(user) interfaces will be able to connect to
central business logic.

In 4GL coding (GetCreditlimit.p)
DEFINE INPUT PARAMETER iCustNum AS INTEGER
NO-UNDO. DEFINE OUTPUT PARAMETER oOrderTotal AS
DECIMAL NO-UNDO. DEFINE OUTPUT PARAMETER
oCreditLimit AS DECIMAL NO-UNDO. DEFINE OUTPUT
PARAMETER oOverCredit AS LOGICAL NO-UNDO. FIND
FIRST Customer WHERE / Calculate Order Total
/ FOR EACH order OF customer NO-LOCK, / Check
Credit Limit / IF oOrderTotal gt
customer.creditlimit THEN ASSIGN oOverCredit
TRUE. ELSE ASSIGN oOverCredit FALSE.
17
Client side coding

• VB.NET
• Dim orders As New OEDemo_Orders
  (Appserver//nbtvanpol5162/ASOpenEdgeSL, "",
  "","")
• orders.GetCreditLimit(cCustNum, ototal, oLimit,
  oOverLimit)

• JAVA / C
• OEDemo_Orders orders new OEDemo_Order
  ("Appserver//nbtvanpol5162/ASOpenEdgeSL","","",
  )
• orders.GetCreditLimit(cCustNum, ototal, oLimit,
  oOverLimit)

If your app is a success
you will encounter other Apps
in all sorts of technologies
what about integration ???

Cant we keep it simple?

• ASCII, CVS, XML, ?
• FTP/HTTP/TCP/File Polling?
• Security? User Maintenance?
• Reliability guarantees?
• High Availability? FT?
• Centralized Logging?
• Firewalls? Certificates?

21
Web Services solve all your problems
22
DO they solve the problem?

• Its an interface, not an architecture!
• Not every application is able to handle/migrate
  to Web Services
• Reliability guarantees?
• High Availability? FT?
• Centralized Logging?
• Firewalls? Certificates?

In Summary

• SOA is a processyou can take it step by
  stepBUT you have to start stepping!
• Use the standards that are available today!
  (But keep in mind that not everyone is capable
  of doing so)
