Active Data - Enabling Smart Data Life Cycle Management for Large Distributed Scientific Data Sets / Active Data − Gestion Intelligente du Cycle de Vie des Grands Jeux de Données Scientifiques Distribués

Simonet, Anthony 08 July 2015 (has links)
Dans tous les domaines, le progrès scientifique repose de plus en plus sur la capacité à exploiter des volumes de données toujours plus gigantesques. Alors que leur volume augmente, la gestion de ces données se complexifie. Un point clé est la gestion du cycle de vie des données, c'est à dire les diverses opérations qu'elles subissent entre leur création et leur disparition : transfert, archivage, réplication, suppression, etc. Ces opérations, autrefois simples, deviennent ingérables lorsque le volume des données augmente de manière importante, au vu de l'hétérogénéité des logiciels utilisés d'une part, et de la complexité des infrastructures mises en œuvre d'autre part.Nous présentons Active Data, un méta-modèle, une implémentation et un modèle de programmation qui permet de représenter formellement et graphiquement le cycle de vie de données présentes dans un assemblage de systèmes et d'infrastructures hétérogènes, en exposant naturellement la réplication, la distribution et les différents identifiants des données. Une fois connecté à des applications existantes, Active Data expose aux utilisateurs ou à des programmes l'état d'avancement des données dans leur cycle de vie, en cours d'exécution, tout en gardant leur trace lorsqu'elles passent d'un système à un autre.Le modèle de programmation Active Data permet d'exécuter du code à chaque étape du cycle de vie des données. Les programmes écrits avec Active Data ont à tout moment accès à l'état complet des données, à la fois dans tous les systèmes et dans toutes les infrastructures sur lesquels elles sont distribuées. Nous présentons des évaluations de performance et des exemples d'utilisation qui attestent de l'expressivité du modèle de programmation et de la qualité de l'implémentation. Enfin, nous décrivons l'implémentation d'un outil de Surveillance des données basé sur Active Data pour l'expérience Advanced Photon Source qui permet aux utilisateurs de suivre la progression de leurs données, d'automatiser la plupart des tâches manuelles, d'obtenir des notifications pertinente parmi une masse gigantesque d'événements, ainsi que de détecter et corriger de nombreuses erreurs sans intervention humaine.Ce travail propose des perspectives intéressantes, en particulier dans les domaines de la provenance des données et de l'open data, tout en facilitant la collaboration entre les scientifiques de communautés différentes. / In all domains, scientific progress relies more and more on our ability to exploit ever growing volumes of data. However, as datavolumes increase, their management becomes more difficult. A key point is to deal with the complexity of data life cycle management,i.e. all the operations that happen to data between their creation and there deletion: transfer, archiving, replication, disposal etc.These formerly straightforward operations become intractable when data volume grows dramatically, because of the heterogeneity ofdata management software on the one hand, and the complexity of the infrastructures involved on the other.In this thesis, we introduce Active Data, a meta-model, an implementation and a programming model that allow to represent formally and graphically the life cycle of data distributed in an assemblage of heterogeneous systems and infrastructures, naturally exposing replication, distribution and different data identifiers. Once connected to existing applications, Active Data exposes the progress of data through their life cycle at runtime to users and programs, while keeping their track as it passes from a system to another.The Active Data programming model allows to execute code at each step of the data life cycle. Programs developed with Active Datahave access at any time to the complete state of data in any system and infrastructure it is distributed to.We present micro-benchmarks and usage scenarios that demonstrate the expressivity of the programming model and the implementationquality. Finally, we describe the implementation of a Data Surveillance framework based on Active Data for theAdvanced Photon Source experiment that allows scientists to monitor the progress of their data, automate most manual tasks,get relevant notifications from huge amount of events, and detect and recover from errors without human intervention.This work provides interesting perspectives in data provenance and open data in particular, while facilitating collaboration betweenscientists from different communities.

No. of bitstreams: 1 Claudio Miraldo.pdf: 1423858 bytes, checksum: 3a3a49b4e2e0f0eff50452e01285f090 (MD5) Previous issue date: 2016-11-29 / The Active Conflict Mediation was defined as a concept and a method of conflict resolution that seeks consensus and facilitating dialogue between the parties. With this point of vision the Nacional Agency of Suplementary Health of Brazil (ANS) established a procedure called Intermediation Preliminary Notification (NIP), which allows the regulatory agency intermediate conflicts between beneficiaries and health care providers more quickly. From the perspective of healthcare companies these notifications can mean a high cost if not answered promptly. The aim of this work is to present a solution through the implementation of a computerized system requests management and workflow, so that healthcare companies can have ways to ensure the process of responding to requests with a quick information retrieval, allowing answers to ANS, others agencies and the media, timely whenever necessary. This work demonstrates that the implementation of a computerized system contributed to the efficiency of service and improvement of the quality of the services provided by the health care company, presenting significant results in quantitative terms, as well as providing indicators that allow managers to perform real-time monitoring, historical reporting, and quick retrieval of documents. It was used the methodology of action research (Martins & Theóphilo, 2009) in this work and it could contribute to the improvement of services and reduction of risks arising from primary intermediation notifications in healthcare companies. / A Mediação Ativa de Conflitos foi definida como um conceito e um método de solução de conflitos que visa o consenso e a facilitação do diálogo entre as partes. Com esta visão a Agência Nacional de Saúde Complementar (ANS) estabeleceu um procedimento chamado Notificação de Intermediação Preliminar (NIP), que permite à agência reguladora intermediar e mediar conflitos entre os beneficiários e as operadoras de saúde com mais agilidade. Sob a ótica das operadoras estas notificações podem significar um elevado custo caso não sejam respondidas tempestivamente. O objetivo deste trabalho é apresentar uma solução, por meio da implantação de um sistema informatizado de gestão de solicitações e fluxo de trabalho, para que operadoras de saúde possuam meios de garantir o processo de atendimento às solicitações com uma rápida recuperação de informações, permitindo respostas a ANS, respostas a demais órgãos reguladores e resposta a mídia, tempestivamente, sempre que necessário. Como resultado este trabalho demonstra que a implantação de um sistema informatizado contribuiu para eficiência do atendimento e melhoria da qualidade dos serviços prestados de uma operadora de saúde, tendo apresentado como resultados significativos em termos quantitativos, além de proporcionar a apresentação de indicadores que permitem aos gestores fazer a monitoração da operação em tempo real, relatórios históricos e rápida recuperação dos documentos do processo. Neste trabalho foi utilizada a metodologia de pesquisa-ação (Martins & Theóphilo, 2009) e o resultado deve contribuir para as operadoras de saúde que buscam melhorias dos serviços prestados e diminuição dos riscos decorrentes das notificações de intermediação preliminar.

No. of bitstreams: 1 tassioferenzinimartinssirqueira.pdf: 6506958 bytes, checksum: 2145670dd9a80dec1aef328a3f8a0427 (MD5) Previous issue date: 2016-07-12 / Um ecossistema de software científico, além de outras funcionalidades, busca integrar todas as etapas de um experimento, e comumente utiliza workflows científicos para a resolução de problemas complexos. Toda modificação ocorrida em um experimento deve ser propagada para os workflows associados, os quais devem ser mantidos e evoluídos para o prosseguimento com sucesso da pesquisa. Um das forma de garantir este controle é através da gerência de configuração. Para que ela possa ser utilizada, é importante o armazenamento dos dados de execução e modelagem do experimento e workflows associados. Neste trabalho, utilizamos conceitos e modelos relacionados à proveniência de dados para o armazenamento e consulta destes dados. O uso da proveniência de dados traz alguns benefícios neste armazenamento e consulta, conforme veremos nesta dissertação. Assim, nesse trabalho é proposta uma arquitetura para gerenciar a evolução e manutenção de experimentos e workflows científicos, denominada E-SECO ProVersion. A motivação para a especificação e implementação da arquitetura veio a partir da realização de uma revisão sistemática e de um estudo para verificar características de manutenção e evolução em repositórios de workflows existentes. A partir destas análises, as principais funcionalidades da arquitetura foram definidas e detalhadas. Além disso, um roteiro com diretrizes de uso e provas de conceito utilizando workflows extraídos do repositório myEx-periment foram apresentados, com o objetivo de avaliar a aplicabilidade da arquitetura. / A scientific software ecosystem, in addition to other features, seeks to integrate all stages of an experiment, and commonly used scientific workflows to solve complex problems. Any changes that occurred in an experiment must be propagated to the associated workflows, which must be maintained and evolved for further successful research. One of the way to ensure this control is through configuration management. So that it can be used, it is important the storage of performance data and modeling of the experiment and associated workflows. In this study, we use the concepts and models related to the source of data for storage and retrieval of this data. Use the data source brings some advantages in storage and query, as we will see in this dissertation. Thus, this paper proposes an architecture to manage the development and maintenance of scientific experiments and workflows, called E-SECO ProVersion. The motivation for the specification and implementation of architecture came from the realization of a systematic review and a study to check maintenance characteristics and evolution in existing workflows repositories. From these analyzes, the main features of the architecture are defined and detailed. In addition, a roadmap with usage guidelines and proofs of concept using workflows extracted from myExperiment repository were presented in order to evaluate the applicability of architecture.

Standardy modelování podnikových procesů / Business Process Modeling Standards

Mezera, Jiří January 2010 (has links)
Today, business process modelling is important part of analysis and design of the information systems. There is number of standards, which is concerned with process modelling, whereas each of them represents a little different approach. The project Opensoul created general metamodel, which defines basic elements and their mutual associations, which all standards should meet. In other words, it defines basic rules for process modelling. The goal of this thesis is to compare chosen standards of process modelling with Business process metamodel of Opensoul initiative. The results of this comparison would have provide basis to answer the question, which standard supports in the best way the rules of process modelling defined by metamodel through the system of elements and their associations. This goal requires specifying the method, on which basis the comparison will be made. This method comprises the extension of metamodel with new elements and their relations to other elements, and the extension of some elements with some workflow patterns defined by Workflow Patterns initiative. That is the main benefit of this thesis.

La vérification de patrons de workflow métier basés sur les flux de contrôle : une approche utilisant les systèmes à base de connaissances / Control flow-based business workflow templates checking : an approach using the knowledge-based systems

Nguyen, Thi Hoa Hue 23 June 2015 (has links)
Cette thèse traite le problème de la modélisation des patrons de workflow sémantiquement riche et propose un processus pour développer des patrons de workflow. L'objectif est de transformer un processus métier en un patron de workflow métier basé sur les flux de contrôle qui garantit la vérification syntaxique et sémantique. Les défis majeurs sont : (i) de définir un formalisme permettant de représenter les processus métiers; (ii) d'établir des mécanismes de contrôle automatiques pour assurer la conformité des patrons de workflow métier basés sur un modèle formel et un ensemble de contraintes sémantiques; et (iii) d’organiser la base de patrons de workflow métier pour le développement de patrons de workflow. Nous proposons un formalisme qui combine les flux de contrôle (basés sur les Réseaux de Petri Colorés (CPNs)) avec des contraintes sémantiques pour représenter les processus métiers. L'avantage de ce formalisme est qu'il permet de vérifier non seulement la conformité syntaxique basée sur le modèle de CPNs mais aussi la conformité sémantique basée sur les technologies du Web sémantique. Nous commençons par une phase de conception d'une ontologie OWL appelée l’ontologie CPN pour représenter les concepts de patrons de workflow métier basés sur CPN. La phase de conception est suivie par une étude approfondie des propriétés de ces patrons pour les transformer en un ensemble d'axiomes pour l'ontologie. Ainsi, dans ce formalisme, un processus métier est syntaxiquement transformé en une instance de l’ontologie. / This thesis tackles the problem of modelling semantically rich business workflow templates and proposes a process for developing workflow templates. The objective of the thesis is to transform a business process into a control flow-based business workflow template that guarantees syntactic and semantic validity. The main challenges are: (i) to define formalism for representing business processes; (ii) to establish automatic control mechanisms to ensure the correctness of a business workflow template based on a formal model and a set of semantic constraints; and (iii) to organize the knowledge base of workflow templates for a workflow development process. We propose a formalism which combines control flow (based on Coloured Petri Nets (CPNs)) with semantic constraints to represent business processes. The advantage of this formalism is that it allows not only syntactic checks based on the model of CPNs, but also semantic checks based on Semantic Web technologies. We start by designing an OWL ontology called the CPN ontology to represent the concepts of CPN-based business workflow templates. The design phase is followed by a thorough study of the properties of these templates in order to transform them into a set of axioms for the CPN ontology. In this formalism, a business process is syntactically transformed into an instance of the CPN ontology. Therefore, syntactic checking of a business process becomes simply verification by inference, by concepts and by axioms of the CPN ontology on the corresponding instance.

Existem muitas pesquisas voltadas para o gerenciamento e execução de experimentos baseados em workflows. No entanto, experimentos complexos envolvem interações entre pesquisadores geograficamente distribuídos, demandando utilização de grandes volumes de dados, serviços e recursos computacionais distribuídos. Este cenário categoriza um ecossistema de experimentação científica. Para conduzir experimentos neste contexto, cientistas precisam de uma arquitetura flexível, extensível e escalável. Durante o processo de experimentação, informações valiosas podem ser perdidas e oportunidades de reutilização de recursos e serviços desperdiçadas, caso a arquitetura de ecossistema para e-Science não considere estes aspectos. Com o objetivo de tratar a flexibilidade, a extensibilidade e a escalabilidade de plataformas de ecossistemas, este trabalho apresenta uma arquitetura orientada a serviços apoiada por uma rede ponto a ponto, desenvolvida para tratar as etapas do ciclo de vida de um experimento científico. Este trabalho apresenta como contribuições uma arquitetura para ecossistemas de software científico, a implementação desta arquitetura, bem como a sua avaliação. / The conception of scientific workflows is a widely used approach in the context of e- Science and scientific experimentation. There are many researches about the management and execution of experiments based on workflows. However, scientific experiments involve complex interactions between geographically distributed researchers, requiring the usage of large amount of data, services and distributed computing resources. This scenario categorizes a scientific experimentation ecosystem. In order to carry out experiments in this context researchers need an architecture for e-Science that supports flexibility, extensibility and scalability. During the experimentation process, valuable information can be unexploited and reusing opportunities of resources and services could be lost if the ecosystem architecture for e-Science does not consider previous mentioned requirements. In order to address the flexibility, extensibility and scalability of ecosystems platforms, this dissertation presents a service-oriented architecture supported by a peer-to-peer network. It was developed to support life-cycle stages of a scientific experiment. This work also presents, as contributions, an architecture to support experiments execution of scientific software ecosystems, the implementation of this architecture, as well as its evaluation.

Abordagem algébrica para seleção de clones ótimos em projetos genomas e metagenomas / Algebraic approach to optimal clone selection in genomics and metagenomics projects.

Mauricio Egidio Cantão 01 December 2009 (has links)
Devido à grande diversidade de microrganismos desconhecidos no meio ambiente, 99% deles não podem ser cultivados nos meios de cultura tradicionais dos laboratórios. Para isso, projetos metagenômicos são propostos para estudar comunidades microbianas presentes no meio ambiente, a partir de técnicas moleculares, em especial o seqüenciamento. Dessa forma, para os próximos anos é esperado um acúmulo de seqüências produzidas por esses projetos. As seqüências produzidas pelos projetos genomas e metagenomas apresentam vários desafios para o tratamento, armazenamento e análise, como exemplo: a busca de clones contendo genes de interesse. Este trabalho apresenta uma abordagem algébrica que define e gerencia de forma dinâmica as regras para a seleção de clones em bibliotecas genômicas e metagenômicas, que se baseiam em álgebra de processos. Além disso, uma interface web foi desenvolvida para permitir que os pesquisadores criem e executem facilmente suas próprias regras de seleção de clones em bancos de dados de seqüências genômicas e metagenômicas. Este software foi testado em bibliotecas genômicas e metagenômicas e foi capaz de selecionar clones contendo genes de interesse. / Due to the wide diversity of unknown organisms in the environment, 99% of them cannot be grown in traditional culture medium in laboratories. Therefore, metagenomics projects are proposed to study microbial communities present in the environment, from molecular techniques, especially the sequencing. Thereby, for the coming years it is expected an accumulation of sequences produced by these projects. Thus, the sequences produced by genomics and metagenomics projects present several challenges for the treatment, storing and analysis such as: the search for clones containing genes of interest. This work presents an algebraic approach that defines it dynamically and manages the rules of the selection of clones in genomic and metagenomic libraries, which are based on process algebra. Furthermore, a web interface was developed to allow researchers to easily create and execute their own rules to select clones in genomic and metagenomic sequence database. This software was tested in genomics and metagenomics libraries and it was able to select clones containing genes of interest.
