PRISMA:: Towards quality, aspect oriented and dynamic software architectures

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 architectural types at a high abstraction level and a configuration language to design the architecture of software systems. The component definition language increases reuse allowing importation of COTS and reduces complexity by integrating two modern software development approaches: Component-Based Software Development and Aspect-Oriented Software Development. The configuration language designs the architecture of software systems by creating and interconnecting instances of the defined types including possible imported COTS. PRISMA has a metalevel with reflexive properties for these two languages. For this reason, the types of PRISMA may evolve and the topologies of PRISMA may be reconfigured dynamically.
