Resumo: | As computer systems become ubiquitous, the demand for rigorous and compositional development methods increase dramatically. In the component-based model driven development (CB-MDD) approach, complex systems (sometimes intractable by humans) are build from simple elements, called components. To achieve the CB-MDD goals towards becoming a rigorously development discipline, components and composition rules must be formalised. Moreover, as requirements continuously evolve, there must be mechanisms to refine and safely extend component-based systems. The BRIC component model formalises the CB-MDD core concepts and supports a constructive design based on composition rules that preserves behavioural properties, but do not provide support for component model evolution. In this work we propose inheritance and refinement relations for BRIC. We define a congruent semantics for this model that considers component structure and behaviour. We define refinement as a preorder relation, which is monotonic with respect to the BRIC composition rules. We enhance this component model with support for extensibility via inheritance. The proposed relations allow extension of functionality, whilst preserving service conformance, which we define by means of a convergence notion. We also establish an algebraic connection between component extensibility and refinement. As far as we are aware this is the first time componente inheritance relations are developed for a formal and sound CB-MDD approach. We also integrate the aspect-oriented paradigm into BRIC. We contribute with an approach to capture, specify and use aspects to safely evolve component-based systems. We establish that components extended by aspects preserve the proposed convergence relation that guarantees service conformance. Furthermore, we establish a connection between componente inheritance and aspects, presenting inheritance as a mechanism to define families of componentes and aspects to capture orthogonal concerns over them. The practical relevance of the proposed relations is illustrated by three case studies. One is an autonomous healthcare system, which evolve by the addition of new functionalities via inheritance and by the modularisation of its crosscutting concerns in a reusable and maintainable manner with aspects. Another case study is a bank system, whose functionalities are progressively realised and extended by refinement and inheritance, respectively. Finally, we model a P2P system extended by inheritance to reduce the network traffic. |

No desenvolvimento baseado em componentes (CB-MDD), sistemas complexos (muitas vezes humanamente intangíveis) são construídos a partir de elementos mais simples, chamados componentes. Para atingir os objetivos desta abordagem na direção de torná-la uma disciplina formal de desenvolvimento, componentes e regras de composição devem ser formalizados. Além disso, considerando que os requisitos de um sistema estão em constante evolução, necessitamos de mecanismos para refinar e estender de forma confiável tais sistemas. O modelo de componentes BRIC formaliza os conceitos chave da abordagem CB-MDD, além de garantir corretude por construção se baseando em regras de composição que preservam propriedades comportamentais. BRIC, porém, por não possuir relações de extensão, não suporta evolução de modelos baseados em componentes. Neste trabalho propomos relações de herança e refinamento para BRIC. Definimos uma semântica congruente que considera tanto a estrutura quanto o comportamento de componentes. Definimos refinamento como uma relação de pré-ordem, a qual é monotônica em relação as regras de composição de BRIC. Estendemos este modelo de componentes com suporte a extensibilidade via herança. As relações propostas permitem extensão de funcionalidade, ao mesmo tempo em que preservam conformidade de serviços, a qual é definida em termos de uma noção de convergência. Estabelecemos também uma conexão algébrica entre extensibilidade de componentes e refinamento. Até onde estamos cientes, este trabalho é pioneiro no desenvolvimento de noções de herança de componentes para uma abordagem CB-MDD formal e consistente. Também integramos o paradigma orientado a aspectos em BRIC. Contribuímos com uma abordagem para capturar, especificar e adotar aspectos no desenvolvimento confiável de sistemas baseados em componentes. Estabelecemos que componentes estendidos por aspectos preservam convergência, o que garante conformidade de serviços. Além disso, desenvolvemos uma conexão entre herança e aspectos, apresentando herança como um mecanismo para definir famílias de componentes e aspectos para capturar conceitos ortogonais sobre as mesmas. Ilustramos a relevância prática das relações propostas através de três estudos de caso. No primeiro, modelamos um sistema autônomo de cuidados médicos, estendido pela adição de novas funcionalidades via herança e pela modularização de conceitos transversais de forma reusável e manutenível via aspectos. Na sequência, modelamos um sistema bancário, cujas funcionalidades são progressivamente implementadas e estendidas pelo uso de herança e refinamento. Finalmente, modelamos um sistema P2P cujo tráfico é reduzido por extensão via herança.porUniversidade Federal de PernambucoPrograma de Pos Graduacao em Ciencia da ComputacaoUFPEBrasilAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessherança de componentesrefinamento de componentescorreção por construçãodesign orientado a aspectos para modelos de componentesconvergência comportamentalCSPcomponent inheritancecomponent refinementcorrectness by constructioncomponent-based aspect-oriented designbehavioural convergenceCSPConstructive extensibility of trust worthy component-based systemsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisdoutoradoreponame:Repositório Institucional da UFPEinstname:Universidade Federal de Pernambuco (UFPE)instacron:UFPETHUMBNAILTESE_JOSE_DIHEGO_DA_SILVA_OLIVEIRA_CIN_UFPE_2016.pdf.jpgTESE_JOSE_DIHEGO_DA_SILVA_OLIVEIRA_CIN_UFPE_2016.pdf.jpgGenerated Thumbnailimage/jpeg1216https://repositorio.ufpe.br/bitstream/123456789/19522/5/TESE_JOSE_DIHEGO_DA_SILVA_OLIVEIRA_CIN_UFPE_2016.pdf.jpg8a9cb9a145f13ed21b3bbe74f4a90453MD55ORIGINALTESE_JOSE_DIHEGO_DA_SILVA_OLIVEIRA_CIN_UFPE_2016.pdfTESE_JOSE_DIHEGO_DA_SILVA_OLIVEIRA_CIN_UFPE_2016.pdfapplication/pdf1113539https://repositorio.ufpe.br/bitstream/123456789/19522/1/TESE_JOSE_DIHEGO_DA_SILVA_OLIVEIRA_CIN_UFPE_2016.pdf124effe0f62c8dd44008517c1e0045eeMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
