The development of software systems must be done using platforms that allow the description of quality, complex, distributed, dynamic and reusable architectural models. We present in this paper PRISMA, an architectural modelling approach based on aspects and components, that uses a component definition language (components, connectors and systems) to define(More)
Model-driven engineering (MDE), implicitly based upon meta-model principles, is gaining more and more attention in software systems due to its inherent benefits. Its use normally improves the quality of the developed systems in terms of productivity, portability, inter-operability and maintenance. Therefore, its exploitation for the development of(More)
Aspect-Oriented Programming (AOP) has emerged in recent years as a new paradigm for software development. PRISMA is an approach for developing complex and large software systems. It combines the Aspect-Oriented Software Development (AOSD) and the Component-Based Software Development (CBSD) in an elegant and novel way achieving a better management of(More)
The impact of architecture is not only significant in the final structure of software, but also in the development process. Architecture itself is assembled by a network of design decisions (DD) composing a design rationale. Such rationale has often been neglected; however it is essential to deal with future change. This is also the role of traceability,(More)
— As the software for avionics becomes more complex, the challenge to provide the required reliability and safety mechanisms becomes also more complex. Embracing the ARINC 650 and 653 standards to provide a means to embark several systems into a single hardware cabinet opens the door to the development of even more elaborated software avionics systems, by(More)
