In this paper we propose a new software development process which is called M2T (MDA 2 Tracks). The M2T process provides an implementation of the MDA approach while relying on a Y shaped development cycle. The left branch of the Y cycle corresponds to Platform Independent Model (PIM) while the right one corresponds to what we call an explicit Platform Description Model (PDM) representing the ta...

The MDA (Model Driven Architecture) is a new way of writing specifications and developing applications, based on a platform-independent model. A complete MDA specification consists of a definitive platformindependent base UML model, plus one or more platform-specific models and interface definition sets, each describing how the base model is implemented on a different middleware platform. A MDA...

The Model Driven Architecture (MDA) approach defined by OMG advocates a clear separation between platform-independent models (PIMs) and platform-specific models (PSMs) in distributed applications. As such, MDA would ease the migration of applications to new platforms. However, it deals only with the evolution of the platform underlying the applications not the evolution of the business part of ...

The most common applications of the today’s IT world are information systems. The problems related to their design and implementation have sufficiently been solved. However, the true problems occur when an IS is already deployed and user requirements change. In this paper we introduce DaemonX – an evolution management framework which enables to manage evolution of complex applications efficient...

There is a need to integrate XML schemas, i.e., schemas written in XML Schema, into UML-based software development processes. Not only the production of XML schemas out of UML models is required, but even more the integration of given XML schemas as input into the development process. In the model driven architecture, a two step integration is assumed, comprising a platform specific model and a...

Mapping and transformation is a twin process in a high level system abstraction, which they playing corner stone of model driven architecture (MDA) technique. But the researchers on this field gave most attention for the static systems abstraction, while we find that almost systems in the world are dynamic with high frequency behavior changing. In this paper we will focus on what is the work ha...
