XATA 2006: XML: aplicações e tecnologias associadas

Esta é a quarta conferência sobre XML e Tecnologias Associadas. Este evento tem-se tornado um ponto de encontro para quem se interessa pela temática e tem sido engraçado observar que os participantes gostam e tentam voltar nos anos posteriores. O grupo base de trabalho, a comissão científica, também tem vindo a ser alargada e todos os que têm colaborado com vontade e com uma qualidade crescente ano após ano. Pela quarta vez estou a redigir este prefácio e não consigo evitar a redacção de uma descrição da evolução da XATA ao longo destes quatro anos: 2003 Nesta "reunião", houve uma vintena de trabalhos submetidos, maioritariamente da autoria ou da supervisão dos membros que integravam a comissão organizadora o que não envalidou uma grande participação e acesas discussões. 2004 Houve uma participação mais forte da comunidade portuguesa mas ainda com números pouco expressivos. Nesta altura, apostou-se também numa forte participação da indústria, o que se traduziu num conjunto apreciável de apresentações de casos reais. Foi introduzido o processo de revisão formal dos trabalhos submetidos. 2005 Houve uma forte adesão nacional e internacional (Espanha e Brasil, o que para um evento onde se pretende privilegiar a língua portuguesa é ainda mais significativo). A distribuição geográfica em Portugal também aumentou, havendo mais instituições participantes. Automatizaram-se várias tarefas como o processo de submissão e de revisão de artigos. 2006 Nesta edição actual, e contrariamente ao que acontece no plano nacional, houve um crescimento significativo. Em todas as edições, tem sido objectivo da comissão organizadora, previlegiar a produção científica e dar voz ao máximo número de participantes. Nesse sentido, este ano, não haverá oradores convidados, sendo o programa integralmente preenchido com as apresentações dos trabalhos seleccionados. Apesar disso ainda houve uma taxa significativa de rejeições, principalmente devido ao elevado número de submissões. Foi introduzido também, nesta edição, um dia de tutoriais com o objectivo de fornecer competências mínimas a quem quer começar a trabalhar na área e também poder assistir de uma forma mais informada à conferência. Se analisarmos as temáticas, abordadas nas quatro conferências, percebemos que também aqui há uma evolução no sentido de uma maior maturidade. Enquanto que no primeiro encontro, os trabalhos abordavam problemas emergentes na utilização da tecnologia, no segundo encontro a grande incidência foi nos Web Services, uma nova tecnologia baseada em XML, no terceiro, a maior incidência foi na construção de repositórios, motores de pesquisa e linguagens de interrogação, nesta quarta edição há uma distribuição quase homogénea por todas as áreas temáticas tendo mesmo aparecido trabalhos que abordam aspectos científicos e tecnológicos da base da tecnologia XML. Desta forma, podemos concluir que a tecnologia sob o ponto de vista de utilização e aplicação está dominada e que a comunidade portuguesa começa a fazer contributos para a ciência de base.Microsoft

XATA 2005: XML: aplicações e tecnologias associadas

Esta é a terceira conferência sobre a temática do XML, que tenta reunir anualmente a comunidade XML portuguesa. Olhando para o passado, e estudando o que aconteceu, podemos observar uma evolução interessante. Na primeira conferência (2003), houve uma vintena de trabalhos submetidos, maioritariamente da autoria ou da supervisão dos membros que integravam a comissão organizadora. Na segunda conferência (2004), houve uma participação mais forte da comunidade portuguesa mas ainda com números pouco expressivos. Nesta altura, apostou-se também numa forte participação da indústria, o que se traduziu num conjunto apreciável de apresentações de casos reais. Nesta terceira edição, a participação excedeu as nossas expectativas. Houve uma forte adesão nacional e internacional (Espanha e Brasil, o que para um evento onde se pretende privilegiar a língua portuguesa é ainda mais significativo). A distribuição geográfica em Portugal também aumentou, havendo mais instituições participantes. Se analisarmos as temáticas, abordadas nas três conferências, percebemos que também aqui há uma evolução no sentido de uma maior maturidade. Enquanto que no primeiro encontro, os trabalhos abordavam problemas emergentes na utilização da tecnologia, no segundo encontro a grande incidência foi nos Web Services, uma nova tecnologia baseada em XML e, no terceiro, a maior incidência é na construção de repositórios, motores de pesquisa e linguagens de interrogação. Isto poderá revelar que, de certa forma, os investigadores e os utilizadores já dominam bem a tecnologia, já têm as sua linhas de produção documental em XML e que agora é chegado o momento de armazenar aquela informação em repositórios e de a utilizar a partir deles. Se reflectirmos um pouco sobre o ciclo de vida documental, podemos concluir que o armazenamento aparece como uma das últimas fases. Por isso, podemos dizer que a comunidade portuguesa de XML "está a fechar" o ciclo de desenvolvimento documental XML. Nesta edição, houve um elevado número de submissões o que levou a uma sobrecarga de trabalho por parte dos revisores. Estes conseguiram desempenhar bem o seu papel e cumprir as datas definidas pelo "chair". Mas o que aconteceu fez-nos pensar que há necessidade de alargar ainda mais a Comissão Científica. Como consequência do número elevado de submissões houve algumas rejeições. Aos respectivos autores, fica aqui expresso um voto para que melhorem os respectivos trabalhos e de que esperamos ter contribuído para isso com os relatórios de revisão que foram enviados.Microsoft Portuga

MACHS: Mitigating the Achilles Heel of the Cloud through High Availability and Performance-aware Solutions

Cloud computing is continuously growing as a business model for hosting information and communication technology applications. However, many concerns arise regarding the quality of service (QoS) offered by the cloud. One major challenge is the high availability (HA) of cloud-based applications. The key to achieving availability requirements is to develop an approach that is immune to cloud failures while minimizing the service level agreement (SLA) violations. To this end, this thesis addresses the HA of cloud-based applications from different perspectives. First, the thesis proposes a component’s HA-ware scheduler (CHASE) to manage the deployments of carrier-grade cloud applications while maximizing their HA and satisfying the QoS requirements. Second, a Stochastic Petri Net (SPN) model is proposed to capture the stochastic characteristics of cloud services and quantify the expected availability offered by an application deployment. The SPN model is then associated with an extensible policy-driven cloud scoring system that integrates other cloud challenges (i.e. green and cost concerns) with HA objectives. The proposed HA-aware solutions are extended to include a live virtual machine migration model that provides a trade-off between the migration time and the downtime while maintaining HA objective. Furthermore, the thesis proposes a generic input template for cloud simulators, GITS, to facilitate the creation of cloud scenarios while ensuring reusability, simplicity, and portability. Finally, an availability-aware CloudSim extension, ACE, is proposed. ACE extends CloudSim simulator with failure injection, computational paths, repair, failover, load balancing, and other availability-based modules

Systematische Prozessunterstützung für die Entwicklung laufzeitkritischer Softwaresysteme: Systematische Prozessunterstützung für die Entwicklung laufzeitkritischer Softwaresysteme: PROKRIS-Methodik und -Framework

In vielen Bereichen des täglichen Lebens, angefangen vom Online-Banking bis hin zur Steuerung im Flugzeug, kommt Software mit laufzeitkritischen nicht-funktionalen Eigenschaften (NFE) zum Einsatz. Die Erfüllung der NFE spielt in diesen Anwendungen eine zentrale Rolle. Um dies zu erreichen, ist eine systematische und zielorientierte Behandlung dieser Anforderungen während der Entwicklung zwingend erforderlich. NFE zeichnen sich im Gegensatz zu funktionalen Eigenschaften durch besondere Merkmale aus, die ein adaptives Vorgehen zur Definition des Entwicklungsprozesses erzwingen. In der Arbeit wird eine Methodik zur kontextbasierten Anpassung von Vorgehensmodellen an laufzeitkritische NFE auf der Basis von Prozessmustern sowie das PROKRIS-Framework als unterstützende Umgebung vorgestellt

Design principles for supply network systems

Supply networks crossing organizational boundaries become more and more critical for success in the dynamics of supply relationships. The ability to quickly find, connect and qualify business partners as sources of supply on a regional, national and international basis, and to sustain those relationships crossing intercultural barriers along the completion of business cases, is and will remain a key competitive differentiator in the global economy. Supply networks in particular are characterized by wide inter-organizational settings of connected entities, with the key focus on supply management and procurement in the provision of goods and services. As such, they describe the value generation flow between connected business partners. Supporting supply networks on an individual company level, the primary target of enterprise resource planning systems is to standardize structured data and to streamline business processes within a company. Extending this scope, e-procurement and supplier-relationship management systems focus on supply networks beyond the boundary of a single company. They enable integration across companies by establishing standards for document exchange between different systems. However, these approaches still result in costly, rigid, and complex data and process integration of peer-to-peer nodes in dynamic supply networks. Also, the emergence of e-marketplaces in the early 2000s could not overcome these challenges, and many of the most promising e-marketplace providers and concepts disappeared when the .com-bubble burst – primarily because of the data and process integration complexity that arises when connecting dyadic and many-to-many network relationships on a single platform. Besides this integration challenge, e-procurement and supplier-relationship management systems are targeted on streamlining structured business processes and handling of structured data. Structured data and processes have fixed coded meaning, format and sequence - from start to completion of a business transaction. Structured data is normally stored in database fields, and structured processes follow pre-defined patterns of transactional steps to complete standardized business cases. The coverage of structure data and processes is mostly sufficient where the use case is commonly defined and accepted by the involved business partners, composed mostly of routine steps and not requiring much direct human interaction. To cope with the increasing challenges in the highly collaborative, inter-organizational settings and to leverage Web 2.0 and Enterprise 2.0 capabilities in supply networks, the support of unstructured interactions become more important. Unlike structured data and processes, unstructured interactions like instant messages, feeds, or blogs have no or limited fixed format, are directly derived from human interactions resulting in textual data, and can hardly be computed without any prior transformation. Many of these happen before, during, and after the actual execution of structured business processes, but are rarely supported by the corresponding supply management systems. This is a particular challenge, as Cappuccio (2012) predicts that enterprise data will grow by 650% over the next five years, with 80% of that data being unstructured. In summary, by designing systems providing utility for companies and business professionals in supply networks, the two comprehensive challenges of (1) data and process integration and (2) support of unstructured interactions need to be addressed. Addressing these challenges, the doctoral thesis proposes a design that tightly bundles both structured and unstructured data and process perspectives - following suggestions “[to find] new ways to generate and maintain connections within and between social units, and new social connection-focused IT capabilities” (Oinas-Kukkonen et al. 2010, p. 61). Through not looking at both challenges independently, the overarching research question is: Which design principles instantiated in a software artifact advance supply networks for professionals, by connecting both structured and unstructured data and processes? The answer to this research question consists of aggregated design principles for the design and implementation of supply network systems supporting business professionals in supply management and procurement. Their individual performance in supply networks should increase, and their effort to execute supply network tasks should decrease, assuming that improvements at individual levels will also lead to supply network advances overall. In order to answer the research question, Action Design Research (ADR) is employed, based on the Design Science Research (DSR) paradigm. The design principles of ‘networked business objects (n-BO)’ and ‘social augmentation’ are conceptualized, which are used to derive and implement related design decisions in a software artifact. Finally, testable hypotheses are derived and evaluated towards the utility of both the artifact and the underlying design principles
