Welcome to the 5th International Conference on Open Source Systems! It is quite an achievement to reach the five-year mark - that's the sign of a successful enterprise. This annual conference is now being recognized as the primary event for the open source research community, attracting not only high-quality papers, but also building a community around a technical program, a collection of workshops, and (starting this year) a Doctoral Consortium. Reaching this milestone reflects the efforts of many people, including the conference founders, as well as the organizers and participants in the previous conferences. My task has been easy, and has been greatly aided by the hard work of Kevin Crowston and Cornelia Boldyreff, the Program Committee, as well as the Organizing Team led by Bjorn Lundell. All of us are also grateful to our attendees, especially in the difficult economic climate of 2009. We hope the participants found the conference valuable both for its technical content and for its personal networking opportunities. To me, it is interesting to look back over the past five years, not just at this conference, but at the development and acceptance of open source software. Since 2004, the business and commercial side of open source has grown enormously. At that time, there were only a handful of open source businesses, led by RedHat and its Linux distribution. Companies such as MySQL and JBoss were still quite small.

Conceptual modeling has always been one of the cornerstones for information systems engineering as it describes the general knowledge of the system in the so-called conceptual schema.Krogstie, Opdahl and Brinkkemper compiled 20 contributions from renowned researchers covering all aspects of conceptual modeling on the occasion of Arne Slvberg's 67th birthday. Many friends of this information systems modeling pioneer happily contributed their latest research results from fields like data modeling, goal-oriented modeling, agent-oriented modeling, and process-oriented modeling. Overall, the contributions reflect the most important developments and application areas of conceptual modeling in recent years, and they also pinpoint trends in conceptual modeling for the next decade.This wide selection corresponds to the broad spectrum of Arne's activities and long-term responsibilities with the VLDB Endowment, IFIP, and ERCIM. Arne was presented with this book at CAiSE 2007, when the event which he cofounded in 1989 returned to his hometown of Trondheim.

Extensive research and development has produce mutation tools for languages such as Fortran, Ada, C, and IDL; empirical evaluations comparing mutation with other test adequacy criteria; empirical evidence and theoretical justification for the coupling effect; and techniques for speeding up mutation testing using various types of high performance architectures. Mutation has received the attention of software developers and testers in such diverse areas as network protocols and nuclear simulation. Mutation Testing for the New Century brings together cutting edge research results in mutation testing from a wide range of researchers. This book provides answers to key questions related to mutation and raises questions yet to be answered. It is an excellent resource for researchers, practitioners, and students of software engineering.

The papers are centered around topics like architectures and quality of information systems, artificial intelligence in information systems, data and knowledge engineering, enterprise and information systems engineering, security of information systems.

Studienarbeit aus dem Jahr 2016 im Fachbereich Informatik - Software, Note: 2,3, FOM Essen, Hochschule für Oekonomie & Management gemeinnützige GmbH, Hochschulleitung Essen früher Fachhochschule, Sprache: Deutsch, Abstract: Diese Hausarbeit beschreibt die schriftliche Ausarbeitung zum Thema ¿Vorstellung und Vergleich von Vorgehensmodellen in der Softwareentwicklung¿. Sie ist Bestandteil des Faches Software-Engineering im Studiengang Wirtschaftsinformatik. Mit dem ersten Kapitel sollen zunächst Grundbegriffe der Softwareentwicklung erläutert werden. Dabei wird der Begriff Software definiert und zu Beginn die geschichtliche Entwicklung des Software-Engineerings näher erläutert.Durch die erzielten Fortschritte im Bereich der Technik konnten immer leistungsstärkere Rechner entwickelt werden, die auch für sehr komplexe Rechenprozesse bzw. Aufgaben nur noch Bruchteile von Sekunden benötigen. Diese Performancesteigerung war die Basis zur Entwicklung von deutlich komplexeren Anwendungen und Softwaresystemen. Software wurde früher nur für wenige Bereiche wie für wissenschaftliche Einrichtungen, das Militär oder für große Unternehmen hergestellt. Dadurch, dass die Gerätevielfallt für den Einsatz von Software anstieg, haben immer mehr Verbraucher auch ohne professionelle Kenntnisse mit dem Computer, Software bezogen. Nun aber haben wir einen Standpunkt erreicht, in dem es so gut wie kein Unternehmen oder sogar keinen Haushalt gibt, welches keine Software gesteuerten Geräte wie z.B. Computer benutzt. Technologien wie Computer, Tablets, Notebooks oder Smartphones sind längst fester Bestandteil unseres Alltags. Um diesen Wandel zu überstehen, wurde im Gebiet der Softwareentwicklung stets reagiert. Um neue Anforderungen und die damit entstehenden komplexen Herausforderungen zu überstehen, wurden immer neue Methoden und Werkzeuge entwickelt, um die Probleme zu lösen. Eine wichtige Entwicklung ist dabei beispielsweise die objektorientierte Programmierung. Diese schafft virtuelle Objekte, die mit Eigenschaften und Methoden ausgestattet werden können. Durch diese Programmiertechnik kann es sehr einfach sein, komplexe Prozesse einfach darzustellen. In der heutigen Zeit ist die objektorientierte Programmierung deswegen zu einem unverzichtbaren Ansatz der modernen Entwicklung von Softwares-Lösungen geworden. Aber es sind auch weitere Methoden und Techniken im Laufe der Zeit entstanden sind. Einige dieser Methoden werden in den nachfolgenden Kapiteln definiert und vorgestellt.
