Enterprise Integration


How to describe

an integration flow behaviour ?

? ????

??

?


UML ?


UML happens to hurt you…

Optional sequences or alternatives with guard conditions.


… again …Break conditions and parallelism.


… 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 ??


Other candidates ?

BPMN ?OK for modeling options, sequences and parallelismKO for qualifying processing steps

Visio or PowerPoint ?OK if you have defined your own concepts & representations setsDifficult to share (think about your contractors…)Difficult to automate

Text document ?AmbiguousImpossible to automate


Enterprise Integration Patterns

• Gregor Hohpe and Bobby Woolf in 2003• 65 patterns for describing recurring problems



A terminology and its notation for primitives…

Router

Splitter

Enricher



With some defined assemblies

Normalizer

Scatter-Gather


EIP Support

A « de-facto standard » claimed by major vendors

- Just a source code abstraction…- Implicit mapping most of time !


But…designer for EIP

designer for EIP

EIP is not a language, has no metamodel. It’s just a notation…


1st step : « Conceptualize Everything »

EIP MetaModel


Enterprise Architecture


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 ? »


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 InterfaceSpecification

Describe exchanged data (IN / OUT)


Easy to provide tooling for some…




Service / API Behaviour Specification

Well-known metamodels and standards artifacts

… some others are less obvious !

?


Using EIP for behaviour specification





Bring some fluidity between activities

Use the EIP tooling to ensure transition


2nd step : « Bring fluidity in process »

PDE Model transformation

Model to Text generation


Using EIP for behaviour specification





Adding a feedback loop

Because real-life is never a top-down only

process !


3rd step : « Have a feedback loop »

Model ComparisonPDE


EIP Designer project


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.


EIP Designer

Based on cool Eclipse Modeling Technologies

Open Source (http://github.com/lbroudoux/eip-designer)

Supporting open standards

Spring Integration

Obeo TOGAF Designer

SwitchYard / SCA


What else ?

We’re using it for technical migrations !

Current experimentation at Covéa
