In this talk, I'll introduce an open source designer for Enterprise Integration Patterns (EIP) based on Eclipse Sirius. The goal of this designer is to provide fluidity and continuity whilst filling the gap existing between Enterprise Architecture practices and concrete software development. During this session, I will come back on project genesis and designer realization process. I will show you - through a real world use-case - how the combination of Sirius / EMF / Acceleo and Eclipse plugin technologies may be used to provide efficient, taylored but extensible working environments.

Enterprise Integration

4. @lbroudoux#EIPDesignerSiriusCon
How to describe
an integration flow behaviour ?
? ??
?
?
?
?
?

5. @lbroudoux#EIPDesignerSiriusCon
UML ?

6. @lbroudoux#EIPDesignerSiriusCon
UML happens to hurt you…
Optional sequences or
alternatives with guard
conditions.

7. @lbroudoux#EIPDesignerSiriusCon
… again …
Break conditions and
parallelism.

8. @lbroudoux#EIPDesignerSiriusCon
… and again.
Loop definitions.
Lacks and limits in context of
Enterprise Integration :
- How to qualify a processing step ?
(Acts on data ? Use external
resources ?),
- Readability when having numerous
partners,
- Accessibility : who does
understand ??

9. @lbroudoux#EIPDesignerSiriusCon
Other candidates ?
BPMN ?
OK for modeling options, sequences and parallelism
KO for qualifying processing steps
Visio or PowerPoint ?
OK if you have defined your own concepts & representations sets
Difficult to share (think about your contractors…)
Difficult to automate
Text document ?
Ambiguous
Impossible to automate

10. @lbroudoux#EIPDesignerSiriusCon
Enterprise Integration Patterns
• Gregor Hohpe and Bobby Woolf in 2003
• 65 patterns for describing recurring problems

11. @lbroudoux#EIPDesignerSiriusCon
Enterprise Integration Patterns
A terminology and its notation for primitives…
Router
Splitter
Enricher

12. @lbroudoux#EIPDesignerSiriusCon
Enterprise Integration Patterns
With some defined assemblies
Normalizer
Scatter-Gather

13. @lbroudoux#EIPDesignerSiriusCon
EIP Support
A « de-facto standard » claimed by major vendors
- Just a source code abstraction…
- Implicit mapping most of time !

14. @lbroudoux#EIPDesignerSiriusCon
But…
designer for EIP
designer for EIP
EIP is not a language, has no
metamodel. It’s just a notation…

15. @lbroudoux#EIPDesignerSiriusCon
1st step : « Conceptualize Everything »
EIP MetaModel

16. @lbroudoux#EIPDesignerSiriusCon
Enterprise Architecture

17. @lbroudoux#EIPDesignerSiriusCon
Enterprise Architecture Service vision
Most of EA methodologies have Service and consumptions
concepts
Service
Application
Service
Application
Function
consumes
usesrealizes
But don’t go further and address the question of « how ? »

18. @lbroudoux#EIPDesignerSiriusCon
Service / API Behaviour
Specification Describe internal processing and
partners interactions
Additional activities
Service / API Realization
Enterprise Architecture activities
In order to fill the gap before actually developping
Service / API Interface
Specification
Describe exchanged data (IN /
OUT)

19. @lbroudoux#EIPDesignerSiriusCon
Easy to provide tooling for some…
Service / API Realization
Enterprise Architecture activities
Service / API Interface
Specification
Service / API Behaviour
Specification
Well-known metamodels and
standards artifacts
… some others are less obvious !
?

20. @lbroudoux#EIPDesignerSiriusCon
Using EIP for behaviour specification
Service / API Realization
Enterprise Architecture activities
Service / API Interface
Specification
Service / API Behaviour
Specification
Bring some fluidity between activities
Use the EIP tooling to
ensure transition

21. @lbroudoux#EIPDesignerSiriusCon
2nd step : « Bring fluidity in process »
PDE Model transformation
Model to Text generation

22. @lbroudoux#EIPDesignerSiriusCon
Using EIP for behaviour specification
Service / API Realization
Enterprise Architecture activities
Service / API Interface
Specification
Service / API Behaviour
Specification
Adding a feedback loop
Because real-life is
never a top-down only
process !

23. @lbroudoux#EIPDesignerSiriusCon
3rd step : « Have a feedback loop »
Model ComparisonPDE

24. @lbroudoux#EIPDesignerSiriusCon
EIP Designer project

25. @lbroudoux#EIPDesignerSiriusCon
EIP Designer
A simple, vendor-independant way of formelly describe the
behaviour of an integration flow (aka. an Enterpise
Service),
Kickstarters for generating code templates for the most
commons solutions,
Reverse and control tools for checking development
compliance, detecting design caveats,
A Bridge System to extend other designers such as
Enteprise Architecture oriented ones.
