Want to be study in Modelling Approaches for RIAs?

In a model-driven or model-based approach, we need a model language that provides model
Elements that allow us to model these distinguishing features of RIAs. Depending on the level
Of abstraction, we require different type of model elements. On business level (computational
independent model in the MDA terminology), we need model elements, which allow a draft
representation of the features that the RIA will provide to the user, i.e. the facilities the user
Will perceive. On design level these features need a refinement indicating e.g. more precisely
How is the user interaction and the client-server communication. Finally, when building the
Platform specific model or at code level, the technologies used need to be specified in detail.
The need of an engineering support for RIA development has been recently addressed by
Several methods. We distinguish four types of approaches:
1. The extension of an already existing method with RIA features for modelling,
additional transformations, and specific generation mechanisms, such as OOHRIA,
OOHDM, UWE-R and Web ML.
2. Combination of a method for the development of web applications with a method for
User interfaces design and generation, e.g. RUX combined with Web ML and UWE.
3. A new method for designing and implementing RIAs, e.g. the ADRIA approach and
The work of Martinez-Ruiz et al.
4. Pattern-based approach as the design recommendations based on best practices, e.g.
library proposed by Scott or Mahemoff and the UML-based patterns proposed by
UWE.
