Innovation and the Next Generation of COBOL Apps Take a look at the future. Our live demos show the way forward for modernising COBOL application development and deployment in new architectures. Presenters: Scot Nielsen, Snr Product Manager, COBOL and Alwyn Royall, Solutions Consultant

1. Innovation and the
Next Generation of
COBOL Applications

2. Application modernization encompasses many needs
DATAWeb Services

3. Web services and COBOL
 Mature software architecture,
supported by diverse software
tooling
 Easily integrate with other
programming languages/systems
 Add mobile services to your
application
 Build your ‘API Economy’
“Web Services offers
a rapid approach to
extending COBOL
application logic to
new use cases”

4. Web Services are stateless

5. Web Services using Managed Code
C#/VB/Java/COBOL

6. Web Services using Micro Focus SOA

7. The Demo App
A car allowance mileage log

8. The Trip Log Application
Purpose:
• Collate my business mileage
claims
• Calculate my tax rate based on
total mileage claimed
• Helps me become ‘tax efficient’
How it works:
• Trips entered using
postcode
• Rate tables held internally
• Distances held on look up
ISAM file
• Classic green-screen app in
need of a facelift

9. Wrapping up
• Web Services
• an industry standard approach to extending application value
- well suited to COBOL apps
• Inherently a stateless architecture - but REST helps
• Multiple web service frameworks to choose from - JVM, .NET
or Micro Focus SOA and the IMTK
• We created a COBOL Web Service, Javascript, .NET client,
Android and WPF demos
• What existing application logic can you offer to your clients?
