About MDA - Model Driven Architecture
Allegro use Model Driven Architecture (MDA) methodology, to manage code by conceptual models.
Main concepts of the MDA methodology are :
- A unique Platform Independent Model (PIM), with all business concepts (with MagicDraw UML designer);
- Transform the PIM into one Platform Specific Model (PSM) for each targeted platform :
- PSM are generate by a Model-to-Model transformation, suing MIA-transformation software.
- According to the defined architecture, two PSMs are generated : a client and a server model.
- Use PSFM to generate specific code for the targeted platform :
- Code generation use AndroMDA, a "powerful Open Source MDA Generator".
- Generated files are :
- Web Service layer : Spring configuration file for Xfire;
- Business Layer : Spring configuration, Java Interface and a default implementation,
- DAO layer : Spring configuration, Hibernate mapping files, Java Beans (Entities), CRUD interfaces, default CRUD implementations
