Collaboration and Virtualization in Large Information Systems Projects

A project is evolving through different phases from idea and conception until the experiments, implementation and maintenance. The globalization, the Internet, the Web and the mobile computing changed many human activities, and in this respect, the realization of the Information System (IS) projects. The projects are growing, the teams are geographically distributed, and the users are heterogeneous. In this respect, the realization of the large Information Technology (IT) projects needs to use collaborative technologies. The distribution of the team, the users' heterogeneity and the project complexity determines the virtualization. This paper is an overview of these aspects for large IT projects. It shortly present a general framework developed by the authors for collaborative systems in general and adapted to collaborative project management. The general considerations are illustrated on the case of a large IT project in which the authors were involved.large IT projects, collaborative systems, virtualization, framework for collaborative virtual systems

Doświadczenia międzynarodowe w zakresie systemu elektronicznej identyfikacji

Autorzy mówili modele systemów identyfikacji elektronicznej stosowane w krajach europejskich i USA. W wielu krajach państwo w ramach zapewnienia bezpieczeństwa i interoperacyjności określiło jedynie podstawowe standardy funkcjonowania dla zaangażowanych instytucji. Scharakteryzowano rynek usług zaufania w Europie, podkreślając jego duże zróżnicowanie. Najczęstszą usługą zaufania oferowaną przed przedsiębiorców, instytucji prywatnych i publicznych jest wyda-wanie kwalifikowanych certyfikatów. Natomiast najrzadziej, prawdopodobnie ze względu na poziom skomplikowania przedsięwzięcia dostawcy usług zaufania podejmują się stworzenia kwalifikowanych usług, rejestrowanych elektronicznych doręczeń. Omówiono także kwestie bezpieczeństwa w elektronicznej identyfikacji podejmowane w państwa EU.The authors have discussed the models of electronic identification systems used in the European countries and the USA. In many countries, the state has defined only the basic standards of functioning for the engaged institutions as part of safety and interoperability guarantee. The trust services market in Europe has been defined, while putting an emphasis on its diversity. The most common trust service offered by entrepreneurs or private and public institutions is the issuance of qualified certificates. On the other hand, the trust services providers very rarely undertake to create qualified electronically registered services, probably due to the complexity of the enterprise. Also the issues of electronic identification security undertaken by the EU states

On the Move to Meaningful Internet Systems: OTM 2015 Workshops: Confederated International Workshops: OTM Academy, OTM Industry Case Studies Program, EI2N, FBM, INBAST, ISDE, META4eS, and MSC 2015, Rhodes, Greece, October 26-30, 2015. Proceedings

International audienceThis volume constitutes the refereed proceedings of the following 8 International Workshops: OTM Academy; OTM Industry Case Studies Program; Enterprise Integration, Interoperability, and Networking, EI2N; International Workshop on Fact Based Modeling 2015, FBM; Industrial and Business Applications of Semantic Web Technologies, INBAST; Information Systems, om Distributed Environment, ISDE; Methods, Evaluation, Tools and Applications for the Creation and Consumption of Structured Data for the e-Society, META4eS; and Mobile and Social Computing for collaborative interactions, MSC 2015. These workshops were held as associated events at OTM 2015, the federated conferences "On The Move Towards Meaningful Internet Systems and Ubiquitous Computing", in Rhodes, Greece, in October 2015.The 55 full papers presented together with 3 short papers and 2 popsters were carefully reviewed and selected from a total of 100 submissions. The workshops share the distributed aspects of modern computing systems, they experience the application pull created by the Internet and by the so-called Semantic Web, in particular developments of Big Data, increased importance of security issues, and the globalization of mobile-based technologies

Organisational Intelligence and Distributed AI

The analysis of this chapter starts from organisational theory, and from this it draws conclusions for the design, and possible organisational applications, of Distributed AI systems. We first review how the concept of organisations has emerged from non-organised "blackbox" entities to so-called "computerised" organisations. Within this context organisational researchers have started to redesign their models of intelligent organisations with respect to the availability of advanced computing technology. The recently emerged concept of Organisational Intelligence integrates these efforts in that it suggests five components of intelligent organisational skills (communication, memory, learning, cognition, problem solving). The approach integrates human and computer-based information processing and problem solving capabilities.<br/

E-gov Transparency Implementation Using Multi-agent System: a Brazilian Study-Case in Lawsuit Distribution Process

Electronic government (e-gov) processes need transparency in order to allow citizens to access, understand and verify valuable information in a democratic society. As a crosscutting characteristic, transparency should be present in different e-gov perspectives, such as business processes, information, business rules and information systems. Thus, in this article, we present a multi-agent system (MAS) to implement transparent lawsuit distribution process. We demonstrate that the MAS paradigm emphasizes the organizational operating environment and the information systems alignment, being adequate to implement process transparency under a Brazilian study-case in lawsuit distribution that used real data from the Superior Labor Court of Brazil. The Tropos agent-oriented software development methodology is used to define the hard and soft goals of agents. The MAS architecture and the prototype were defined and implemented using JADE Framework

Code Generation for Big Data Processing in the Web using WebAssembly

Traditional clusters for cloud computing are quite hard to configure and setup, and the number of cluster nodes is limited by the available hardware in the cluster. We hence envision the concept of a Browser Cloud: One just has to visit with his/her web browser a certain webpage in order to connect his/her computer to the Browser Cloud. In this way the setup of the Browser Cloud is much easier than those of traditional clouds. Furthermore, the Browser Cloud has a much larger number of potential nodes, as any computer running a browser may connect to and be integrated in the Browser Cloud. New challenges arise when setting up a cloud by web browsers: Data is processed within the browser, which requires to use the technologies offered by the browser for this purpose. The typically used JavaScript runtime environment may be too slow, because JavaScript is an interpreted language. Hence we investigate the possibilities for computing the work-intensive part of the query processing inside a virtual machine of the web browser. The technology WebAssemby for virtual machines is recently supported by all major browsers and promises high speedups in comparison with JavaScript. Recent approaches to efficient Big Data processing generate code for the data processing steps of queries. To run the generated code in a WebAssembly virtual machine, an online compiler is needed to generate the WebAssembly bytecode from the generated code. Hence our main contribution is an online compiler to WebAssembly bytecode especially developed to run in the web browser and for Big Data processing based on code generation of the processing steps. In our experiments, the runtimes of Big Data processing using JavaScript is compared with running WebAssembly technologies in the major web browsers
