Current realization techniques for service-oriented architectures (SOA) and business process management (BPM) cannot be efficiently applied to any kind of application scenario. For example, an important requirement in the finance sector is the continuous evaluation of stock prices to automatically trigger business processes--e.g. the buying or selling of stocks--with regard to several strategies. In this paper, we address the continuous evaluation of message streams within BPM to establish a common environment for stream-based message processing and traditional business processes. In detail, we propose the notion of standing processes as (i) a process-centric concept for the interpretation of message streams, and (ii) a trigger element for subsequent business processes. The demonstration system focuses on the execution of standing processes and the smooth interaction with the traditional business process environment.

Mémoire numérisé par la Direction des bibliothèques de l'Université de Montréal. / OSI définit une suite de protocoles pour les réseaux ouverts hétérogènes. De tels réseaux peuvent être très difficile à gérer à cause de la diversité des manufacturiers de composantes, chacun définissant sa propre méthode de gestion. C'est pourquoi OSI définit également CMIS, un service générique de gestion de réseaux qui permet de normaliser les interfaces de gestion, c'est-à-dire de les rendre indépendantes de leur manufacturier. Afin d'etre générique, CMTS est très complexe. Il utilise plusieurs autres services d'OSI et peut tenir compte de plusieurs détails des activités de gestion. Une application de gestion utilisant CMIS est donc passablement difficile à réaliser. On trouve sur le marche des plate-forme de développement qui libèrent le programmeur d'une application de gestion des détails de bas niveau, comme le transfert de données entre applications et l'utilisation d'un format de transfert commun. Mais ces interfaces programmatiques sont également très complexes et difficiles à utiliser. C'est pourquoi, dans le cadre de sa maîtrise, l'auteur a développé un cadre d'application qui, se servant d'une interface programmatique de bas niveau, offre au programmeur une interface orientée objet de haut niveau plus facile à utiliser. De plus, le cadre d'application effectue plusieurs tâches génériques de CMIS qui ne sont pas couvertes par l'interface programmatique commerciales. Layla, le cadre d'application, est présenté sous la forme d'un ensemble de patrons de conceptions, de "recettes" à suivre pour réaliser une application. Certains de ces patrons ont déjà été publiés dans la littérature, d'autres sont des adaptations des concepts de CMIS. Enfin, deux de ces patrons sont originaux et ont été formalisés lors de la conception de Layla. Les patrons sont suivis d'une description plus détaillée du cadre d'application et de trois exemples d'applications réalisées avec Layla.

Modern Web or ¿Eternal-Beta¿ applications necessitate a flexible and easy-to-use data management platform that allows the evolutionary development of databases and applications. The classical approach of relational database systems following strictly the ACID properties has to be extended by an extensible and easy-to-use persistency layer with specialized DB features. Using the underlying concept of Software as a Service (SaaS) also enables an economic advantage based on the ¿economy of the scale¿, where application and system environments only need to be provided once but can be used by thousands of users. Within this tutorial, we are looking at the current state-of-the-art from different perspectives. We outline foundations and techniques to build database services based on the SaaS-paradigm. We discuss requirements from a programming perspective, show different dimensions in the context of consistency and reliability, and also describe different non-functional properties under the umbrella of Service-Level agreements (SLA).

No. of bitstreams: 0 Previous issue date: 2009 / Os gastos com saúde vêm aumentando sua participação nas despesas nacionais,parte em função de fatores como a mudança do perfil epidemiológico da população e o envelhecimento da estrutura etária, e parte é atribuída à proliferação e incorporação de novas tecnologias. É necessária a busca pelo equilíbrio: controlar os gastos em saúde sem reduzir o acesso, sem estagnar o processo de desenvolvimento tecnológico do setor e atender as demandas da sociedade. A decisão de incorporação e uso de tecnologias em saúde de forma não sistematizada e sustentável, com pouca ou nenhuma evidência científica, pode implicar em riscos para os usuários e para os profissionais de saúde ou serem ineficientes, sob o ponto de vista do impacto no estado de saúde da população e na definição dos recursos. Na área oncológica vários fatores têm levado a eventuais incorporações ou continuidade de uso de tecnologias em saúde, sem o respaldo em estudos de eficácia, eficiência, efetividade e utilidade devidamente comprovados. Dentre os fatores mais influentes encontram-se a diversidade na oferta de tecnologias, a constante inovação tecnológica e a crescente pressão para incorporação de tecnologias, seja por fornecedores, profissionais ou usuários. Diante disso, existe uma premência em implementar melhorias na gestão de tecnologias em saúde, reconhecendo e fortalecendo o uso de informações embasadas na ciência e no método científico, no processo de tomada de decisão sobre incorporação e uso dessas tecnologias, buscando assim, também, minimizar a utilização ineficiente de recursos. Neste trabalho propõe-se um processo de gestão de tecnologias em saúde para o Instituto Nacional de Câncer, à luz do seu papel como centro de referência de alta complexidade e agente referencial para a prestação de serviços oncológicos no âmbito do Sistema Único de Saúde e das políticas e ações do Ministério da Saúde sobre gestão de tecnologias. A proposição circunscreve-se ao processo de planejamento institucional, de forma a articular as instâncias envolvidas em processos de avaliação, uso, descontinuidade ou incorporação de tecnologias, com base em informações consistentes e fundamentadas, que viabilizem tomada de decisões responsáveis, transparentes e legítimas. / Disbursement of funds for health has increased its share on national public expenditure partly due to factors as changes in the population epidemiologic profile, aging structure decay, and partly owing to the expansion of new technologies implementation. It is necessary to search for balanced health expenditure: to control ought to be sought with no reduction in the accessibility to public health services, neither technological development stagnation of the sector and to consider society demands. The decision of incorporating and using health technologies in a non-systematic and sustainable way, with little or no scientific evidence, may imply risks for users and health professionals or else be inefficient regarding the impact on population health and the definition of resources. As regards oncology, several factors have caused certain incorporations or continuities in the use of health technologies without the support from rightly proven studies on effectiveness, efficiency and usefulness. The diversity of available technologies, the constant technological innovation and the growing pressure towards their incorporation – be it from suppliers, professionals or users – are among the most influent factors. Therefore, there is urgency to implement improvements in the management of health technologies which would recognize and strengthen the use of information based on science and on scientific method, as well as on decision-making processes regarding incorporation and use of these technologies, thus, aiming also to minimize the inefficient use of resources. This study proposes a health technology management process for the Brazilian National Cancer Institute – INCA, considering this institute’s role as a highly complex reference center and agent in oncology assistance in the range of Brazilian Unified National Health System (Sistema Único de Saúde – SUS) and the Ministry of Health policies and actions on technology management. The present proposition is encompassed within the institutional planning process so as to articulate the instances involved in the assessment, use, discontinuity or incorporation of technologies, based on consistent and funded information, which allow for responsible, transparent and legitimate decision making processes.
