This document discusses migrating applications from ABF and OpenROAD to n-tier OpenROAD architectures and HTML5. It describes tools to help analyze existing code and generate 3-tier and HTML5 versions, including the OpenROAD Application Analyzer and a HTML5 frame generator. Consolidate Systems provides services and tools to help customers leverage their applications by migrating them to more modern architectures.

2. Presentation
Consolidate Systems, LLC
New company founded by John Mahony and Roy
Deal Simon
Mission:
Provide Tools and Services to help ABF and
OpenROAD customers leverage the potential of
their Applications

3. Agenda
• Background
• Jenga
• The New Transforge
• Existing OpenROAD Applications
• HTML5
03-06-2011 Copyright Consolidate Systems, LLC 3

4. Background
• Unistar ERP developed by Bording Data
– Written in ABF, C and OpenROAD
– Development started in 1987
– 800.000 lines of 4GL
– 14 Applications
• Converting to OpenROAD will take at least
another 10 calendar years
• TransForge was an option we didn’t like
– Ingres suggested a shared development project
03-06-2011 Copyright Consolidate Systems, LLC 4

5. Outcome
• Transforged Unistar is now running in
production
• Utilizing OpenROAD Server
• No Ingres/Net requirements in client
• Installed and upgraded using LoadnRun
• New effective Development environment

6. TransForge: the good parts
• Discovery process / reporting
• Works out of the box
• Frame layout preserved
• The Business logic is preserved
• 4GL wrappers around C-functions
• Unfortunately into user classes
03-06-2011 Copyright Consolidate Systems, LLC 6

7. The Jenga TransForge
• Code explosion a factor of 6
• Same code generated all over the place
• Not very OpenROAD like
• Strange object wrappers on just about everything
• Upside down frame instantiation
• Very hard to learn and understand
• Insane amount of interdependencies
• You need to decide on stuff you do not know yet
• 2 Tier Ingres/Net based Client
• Styling was close to impossible
• Single frame debugging not possible
• User events used as procedure calls

8. Let’s ”Transforge” TransForge
Objective:
– A new development environment
– Easier to recognize for an ABF Developer
– Generate less code
– No code duplication
• Use include files
– Remove dependency of Ingres/Net
– Untangle the enormous amount of interdependencies
– Utilize OpenROAD Server
03-06-2011 Copyright Consolidate Systems, LLC 8

9. The New TransForge
What did we accomplish?
– Utilize OpenROAD Server
– Eliminate Ingres/Net on Client
• LoadnRun for deployment
– Strange Object wrappers removed
• C-functions wrapped in 4gl procedures
– Code explosion eliminated
– ABF preprocessing
– ABF Previous / Next

10. The New TransForge
• Stylesheets implemented
– a bit like CSS
• SQL-Statements extracted from the code
– can run either at Client or Server
• 3GL wrapped in single 4GL proc
– can run either at Client or Server
• OpenROAD Servers created
– Can run out of the box

12. ASO Explorer

13. SOA Ready
• SQL in a separate application layer
• Accessed by proxy
• 3GL in a separate application layer
• Accessed by proxy
• Data in a separate application Layer
• Shared between Client and Server
• Mixed Remote and Local access
• Configurable for each call

14. SOA in Action
OpenROAD Client Data
(HTTP or Ingres/Net) (Transport Layer)
Local Remote
Proxy
OpenROAD
Server
3GL
SQL
(Data Access Layer)

15. The New TransForge
Generated on the fly

16. Existing OpenROAD Applications
Use the knowledge from the New TransForge
to create OpenROAD Transformations
similar to ABF
03-06-2011 Copyright Consolidate Systems, LLC 16

17. OpenROAD Transformation
• What do we have
– OpenROAD Application Analyzer
– Antlr OpenROAD Parser
• What is planned
– Code Generator
• The Outcome
– 3-tier OpenROAD Applications
• No Ingres/Net dependency in Client
• No SQL in Client
• No 3GL in Client
03-06-2011 Copyright Consolidate Systems, LLC 17

18. OpenROAD Application Analyzer
• Generates an html based “Discovery” report
– Identifies number of statements, and tokens
– Identifies 4GL statement types
– Identifies System, 4GL, UI, External, and Database
dependencies
• All the things that the Workbench does not
provide

20. HTML5
• Objective
• Convert OpenROAD Thin Client to HTML
• Access OpenROAD Servers using Web Services
• What do we have
• OpenROAD Application Analyzer
• Antlr OpenROAD Parser
• HTML 5 Frame Generator
• Generating JavaScript and CSS3

23. Possibilities
Develop in OpenROAD
Generate HTML5 Client
Deploy everywhere:
 Mac
 Smartphones
 Tablets
Business to Business

24. Summary
• How to get ABF to 3-Tier OpenROAD
• The OpenROAD Application Analyzer
• The OpenROAD Server Explorer
• How to get existing OpenROAD Applications
to use OpenROAD Server
• How to generate a HTML5 client from an
OpenROAD client
03-06-2011 Copyright Consolidate Systems, LLC 24

25. Considerations
• Bording and John Mahony have spent more than 8
man-years of enhancing TransForge
• All development has been given back to Ingres
and Consolidate Systems
• You can benefit from our joint effort
