This document discusses using Eclipse Modeling to create a domain-specific language (DSL) to model an enterprise travel agency blog. It describes using a DSL to find the intention of a JavaEE file, generating JavaEE code, and creating custom designers. The goals are to simplify development without needing JavaEE skills, and to integrate the results into an enterprise architecture. Key aspects covered include using conventions for code generation, graphical modeling, importing models from UML, and using the DSLs within different viewpoints of a system designed using an enterprise's own vocabulary.

1. Eclipse Modeling to create your DSL

2. OK, you go to ESE or Eclipse Day Paris.
And now?

3. How to industrialise
JavaEE development?

4. My goals for today:
Use a DSL to find the intention
Generate JavaEE
Create my own designers
Integrate the result in an Enterprise Architecture

11. We can create our own "generator by convention"
Conventions exemples :
An Entity is identify by a technical ID associated to a Sequence
The name of the table is by default the name of the Entity

19. Graphical modeling
"Domain-specific modeling (DSM) is a software engineering
methodology for designing and developing systems, such as
computer software. It involves systematic use of a graphical
domain-specific language (DSL) to represent the various facets of a
system."
