Abstract

Nowadays, the software development demands each time more restrictions of time to market and low costs. Moreover, with the increase of the technological dependence, the software quality and dependability became obligatory requirements for developing computing systems. For speeding the development and reducing its cost, the component-based development (CBD) is being each time more adopted. This paper presents a CBD method which aims to maximise the reuse of existing components, improving at the same time the dependability of the final system. For achieving this, the proposed method adopts an architecture-based solution which acts in three complementary ways: (i) a uniform structure of all the critical architectural elements; (ii) separation of concern between the normal and abnormal (exceptional) behaviours; and (iii) a systematic modelling of the exceptional behaviour since the beginning of the software life cycle. The proposed solution was evaluated through a case study of a real financial application.
