RESUMO

The major goal of this work is to apply object-oriented techniques for structuring complex object-oriented applications, and to relate them to the improvement of quality and reliability of large computer applications. We use a collection of object-oriented concepts, features and mechanisms, such as data abstraction, inheritance, delegation, abstract classes, polymorphism and dynamic binding. We propose an approach for the provision of environmental fault tolerance and distribution, based on the incorporation of redundaucy in an incremental way, so that the complexity can be kept under controI. ln addition, we show how such techniques can be used to develop reusable and easier to extend software components. For the understanding and validation of these techniques, we developed a prototype of an object-oriented distributed and dependable railway controller application. Besides, we use design pattems and metapattems - two promising approaches for software reuse - for developing an object-oriented framework for a railway controller subdomain
