TRANSCRIPT
In this session
User interface generation or execution through MDA
•Our experience in creating real world apps with a model
•The main user interface components “extracted”
•A model is possible & convenient
•Can our model be helpful to you and become a standard model?
Scope
Model to collect the information
Complete & Customize with standard programming tools
Templates, standard objects (tool)
+=
First release u.i.
Modeling tools
A1: Start from data!
1
2
Select the data structure
Complete the user interface information
DBWeb
Service(SOA)
Object model
UML Diagram
Extended model
Q2: Model or code?
The more you try to avoid coding the more …
•Your model will look like a programming tool
•Defining a model will take years
v
More functionalities supported …
•More benefits … (quality and time)
•More specific (internal) training for your development team
•High skills to manage the templates
Workflow, testing,security & authorization, platforms & devices indep., business logic, documentation, localization …
A2: Small steps
Incremental approach:
•Define a model that supports the main functionalities and a standard behavior
•Implement the model
•Test in real world apps to evaluate the results
Q3: The model’s format?•Domain Specific Language
•Class diagram & tagged values
•…
A3:Let’s decide together!
Study on real world apps•Starting from 2006 we analyzed over 100 ERP / departmental (data driven) apps (RPG, COBOL, VB4, VB6, Java, .NET, Ruby …)
•Extracted some common behaviors of the user interface

Hard work & possible!
Excellent results
Always possible & highly recommended!
How to go on …Agile process!
- Continuous delivery of valuable model- Work together- Simplicity- Test model (templates and tool) on real world apps
