This work deals with main goals and principles of ERP systems. On the basis of the presented principles it presents the proALPHA ERP system and examines it in order to determine external access possibilities. The external access into the proALPHA system is the main goal of this work. The materials management module has been chosen as the part of the system to be accessed. The access will be realized via proALPHA INWB module based on Sonic ESB which is described as well. All set goals of this work were reached.

Factory shop floors of the future will see a significant increase in interconnected devices for monitoring and control. However, if a Service Orientated Architecture (SOA) is implemented on all such devices then this will result in a large number of permutations of services and composite services. These services combined with other business level components can pose a huge challenge to manage as it is often difficult to keep an overview of all the devices, equipment and services. This thesis proposes an SOA based novel assimilation architecture for integrating disparate industrial hardware based processes and business processes of an enterprise in particular the plastics machinery environment. The key benefits of the proposed architecture are the reduction of complexity when integrating disparate hardware platforms; managing the associated services as well as allowing the Micro Injection Moulding (µIM) process to be monitored on the web through service and data integration. An Enterprise Service Bus (ESB) based middleware layer integrates the Wireless Sensor Network (WSN) based environmental and simulated machine process systems with frontend Google Gadgets (GGs) based web visualisation applications. A business process framework is proposed to manage and orchestrate the resulting services from the architecture. Results from the analysis of the WSN kits in terms of their usability and reliability showed that the Jennic WSN was easy to setup and had a reliable communication link in the polymer industrial environment with the PER being below 0.5%. The prototype Jennic WSN based µIM process monitoring system had limitations when monitoring high-resolution machine data, therefore a novel hybrid integration architecture was proposed. The assimilation architecture was implemented on a distributed server based test bed. Results from test scenarios showed that the architecture was highly scalable and could potentially allow a large number of disparate sensor based hardware systems and services to be hosted, managed, visualised and linked to form a cohesive business process.

Enterprise Service Bus (ESB) est actuellement l'approche la plus prometteuse pour l'implémentation d'une architecture orientée services (SOA : Service-Oriented Architecture) par l'intégration des différentes applications isolées dans une plateforme centralisée. De nombreuses solutions d'intégration à base d'ESB on été proposées, elles sont soit open-source comme : Mule, Petals, ou encore Fuse, soit propriétaires tels que : Sonic ESB, IBM WebSphere Message Broker, ou Oracle ESB. Cependant, il n'en existe aucune en mesure de traiter, à la fois des aspects : d'intégration et de traitement massivement parallèle, du moins à notre connaissance. L'intégration du parallélisme dans le traitement est un moyen de tirer profit des technologies multicœurs/multiprocesseurs qui améliorent considérablement les performances des ESBs.Toutefois, cette intégration est une démarche complexe et soulève des problèmes à plusieurs niveaux : communication, synchronisation, partage de données, etc.Dans cette thèse, nous présentons l'étude d'une nouvelle architecture massivement parallèle de type ESB.

Cette thèse se situe dans le domaine de l'informatique orientée service. Elle propose un ESB (Enterprise Service Bus) autonomique, c'est-à-dire capable de s'autogérer sur un ensemble d'aspects. Cet ESB, nommé Cilia autonomique, permet de construire des applications de médiation sensibles au contexte. Précisément, la version autonomique de Cilia, que nous proposons, permet l'optimisation de l'utilisation des ressources de la plate-forme d'exécution et l'adaptation dynamique des chaînes de médiation au niveau de la configuration et de la topologie. Notre framework permet également de présenter à tout moment un modèle simplifié des phénomènes liés à l'exécution des chaînes et, ainsi, de faciliter le raisonnement et la prise de décisions d'adaptation. Les travaux de cette thèse ont été validés dans le cadre de l'informatique pervasive. En particulier, Cilia autonomique a été utilisé et instrumenté pour la mise en œuvre d'applications de maintien à domicile et de suivi de la santé des usagers. Les résultats sont disponibles en open source.

Service Oriented Architecture (SOA) is an architectural paradigm that allows building of infrastructures for diverse application interaction and integration via services across different platforms, domains of technology and locations. SOA differs from traditional architectures, as it focuses on integrating capabilities that are distributed and implemented using a mixture of technologies. SOA provides a set of methodologies and strategies to accomplish interoperability and integration among different technology stacks.   Vattenfall is the fifth the largest energy supplier within Europe. Having operational systems in different countries brings the challenge of integrating all these distributed systems and this integration is a vital requirement for Vattenfall. The company is currently using Microsoft proprietary products to achieve integration across different technological platform, but requires a better integration infrastructure which is easily extensible and cost effective.   This thesis investigates the impact of implementing Service Oriented Architecture (SOA) using open source or proprietary software products within Vattenfall, from technological and financial perspectives. For this purpose, different technical and non-technical function blocks are identified which are essential for the implementation of SOA. These function blocks are mapped with SOA solutions provided by Red Hat’s JBoss Open Source SOA Platform and Microsoft’s SOA Platform. After mapping, a vendor specific technical and non-technical comparative analysis is carried out based on the function blocks, highlighting the strengths and weaknesses of each vendor.   Finally, an evaluation scheme is purposed based on the technical comparative analysis of vendors, SOA solution cost and SOA competence required. The results from this evaluation scheme are used to recommend the best solution vendor for Vattenfall Nordic. Moreover, this evaluation scheme can also be used to facilitate management in arriving at an appropriate decision about implementation of SOA, while remaining within their requirements and constraints.

This thesis focuses on design of document exchange solution used between Stavební spořitelna České spořitelny a.s. (SSČS) and its external sales network, which is outdated and doesn't meet the needs of SSČS or sales network. The thesis also includes the identification of suitable basic principles used in the service-oriented architecture (SOA) concept and their application in design solutions. The aim of the thesis is a conceptual solution design, based on the principles of SOA and the following technological design of changes in existing environment, so that on this basis could be created a functional and technical specification for suppliers of these applications. Stated objective is achieved through an initial analysis of the current environment, which identifies the possibilities of existing applications, and identifies weaknesses in the process that will be changed in the new solution. The analysis covers as the environment of external sales network as the related environment in SSČS, which together figure in the process of documentation exchange. As the results of the analysis and based on theoretical knowledge and consultation with experts in the field of SOA is then formulated a proposed solution at the conceptual level, which is further elaborated in the description of the proposed changes in individual components of the new solution. The outputs of this thesis will serve SSČS both in terms of describing the existing and the new environment, and as an input for the specifications of the proposed amendments to the supplier concerned applications. Structure of the thesis consists of introduction, devoted to the characterization of SSČS and providing an initial framework for solved domain. This is followed by a description and the analysis of external sales network, particularly in terms of application equipment and communication flows, followed by a description of the environment in SSČS, which contains the components processing sent documents. Next part of thesis is devoted to the formulation of the basic concepts of SOA and selection of appropriate principles that are followed in the subsequent section to draft the solution itself, first at the conceptual level, followed by a detailed description of the necessary changes. Everything is then evaluated in the final part.

Avec l’évolution des technologies de l’internet, les applications et plus généralement lessystèmes distribués sont de plus en plus conçus en composant et interconnectant un ensemblede services distribués. Ces services pouvant être très hétérogènes, plusieurs approches etsolutions pour la gestion de l’intégration et l’interopérabilité ont été proposées. De toutes cespropositions, les bus de services (ESB – Enterprise Service Bus) ont été désignés commeétant la solution la plus adaptée. Toutefois, le problème avec les ESB est qu’ils sont déployésdans un contexte très évolutif et très dynamique; un contexte dans lequel un grand nombre deservices peuvent être fournis et utilisés de façon concurrente à travers le bus. L’utilisationconcurrente de ces services mais aussi des ressources sous-jacentes allouées au bus (mémoire,processeur, etc.) peut conduire à des événements imprévisibles tels qu’une surcharge du bus,une indisponibilité des services, des temps de réponse élevés, une diminution de la fiabilité,etc. Dans ce contexte, des solutions efficaces permettant de garantir ou d'améliorer à la fois laqualité de service et l'évolutivité offertes par les ESB sont nécessaires. Le but de cette thèse est de proposer les principes architecturaux pour la mise en place un busde service autonome (ASB) qui offre une solution de communication scalable guidée par lestransactions des systèmes interconnectés, mais aussi par les ressources disponibles. L’ASBoffre aussi un service d’intégration différentiée en fonction des exigences en termes de qualitéde service spécifiques aux systèmes interconnectés / With the accelerated evolution of Internet, distributed systems are more and more designed asa composition of distributed services that need to be composed to implement complexbusiness processes. Diversity and heterogeneity of these services raise important integrabilityand interoperability requirements. To meet these needs, the Enterprise Service Bus (ESB) hasbeen proposed as a mediator based on open and standard interfaces facilitating theintegrability and interoperability of services. However, in very active and dynamic contextswhere a large number of concurrent services can be provided and consumed via the ESB, thecompetition for using shared services, but also the underlying computing resources allocatedto the ESB (memory, processor, etc.) can lead to unpredictable events such as serviceunavailability, high response time, decrease of reliability, etc. Such anomalies need to beaddressed by proposing efficient strategies able to guarantee or to improve both the QoS andscalability offered by the ESB. The aim of this thesis is to propose an architectural framework for a QoS-aware AutonomicService Bus (ASB) able to offer in an autonomic way a scalable communication solutionguided by distributed systems transactions and the state of the underlying computingresources. The ASB offers also a differentiated integration service based on the QoSrequirements of interconnected systems

Inom Svensk hälso- och sjukvård sker en stor förändring i IT-infrastruktur. En nationell tjänsteplattform som ska möjligt delning av information mellan vårdgivare i olika regioner har implementerats. Flera landsting och regioner har implementerat liknande arkitekturer lokalt för att uppnå samma effekt även internt, men också för att underlätta uppkoppling till den nationella lösningen.Genom en kvalitativ fallstudie undersöker denna uppsats implementationen av en regional tjänsteplattform i Stockholms Läns Landsting med fokus på styrning. I en teoretisk undersökning behandlas teorier gällande IT inom offentlig hälso- och sjukvård, IT-governance, SOA och SOA-governance.Syftet med studien är att analysera och utvärdera teorier gällande SOA-governance i relation till styrning av en regional tjänsteplattform inom offentlig hälso- och sjukvård och på så sätt bidra till utveckling av aktuella teorier genom en diskussion gällande dess användbarhet inom en specifik sektor. Jag syftar också att bidra till utveckling av den studerade verksamheten genom att identifiera/prognostisera möjligheter och problem med aktuella styrningsstrukturer.Resultaten indikerar att utmaningar för att etablera SOA-governance inom offentlig hälso-och sjukvård främst härstammar ur organisationens natur. Exempelvis Politisk styrning eller lagstiftning. Ramverk för SOA-governance kan inte direkt hantera dessa utmaningar, men kan ge ett stöd genom struktur i arbetet samtidigt som de kan agera rådgivande gällande lösningar som fungerat i andra verksamheter. Rekommendationen är att tidigt i processen fastställa omfång av SOA-projektet, men också dess mål relativt verksamheten. Studien tyder också på att en ökad nytta kan erhållas genom att tidigt i processen etablera en styrande grupp som med ett tydligt mandat beslutar om standarder och säkerställer dess efterlevnad redan under etableringsprojektet.
