Advances in Object-Oriented Information Systems: OOIS 2002 Workshops, Montpellier, France, September 2, 2002 Proceedings (Lecture Notes in Computer Science #2426)
by Jean-Michel Bruel Zohra BellahseneFor the ?rst time four workshops have been held in conjunction with the 8th Object-Oriented Information Systems conference, OOIS 2002, to encourage - teraction between researchers and practitioners. Workshop topics are, of course, inline with the conference’s scienti?c scope and provide a forum for groups of researchers and practitioners to meet together more closely and to exchange opinions and advanced ideas, and to share preliminary results on focused issues in an atmosphere that fosters interaction and problem solving. The conference hosted four one-day workshops. The four selected workshops were fully in the spirit of a workshop session hosted by a main conference. Indeed, OOIS deals with all the topics related to the use of object-oriented techniques for the development of information systems. The four workshops are very speci?c and contribute to enlarging the spectrum of the more general topics treated in the main conference. The ?rst workshop focused on a very speci?c and key c- cept of object-oriented development, the specialization/generalization hierarchy. The second one explored the use of “non-traditional” approaches (at the edge of object-oriented techniques, such as aspects, AI, etc.) to improve reuse. The third workshop dealt with optimization in Web-based information systems. And ?nally the fourth workshop investigated issues related to model-driven software development.

Incident on Simpac III: A Scientific Novel (Science and Fiction)
by Doug BruggeA few hundred years into the future, a wave of space colonization follows a disastrous earlier attempt to inhabit nearby extrasolar planets. It is guided by a new computational method based on massive data-driven socio-cultural and socio-epidemiological modeling and using novel biological computers, fed with data on Earth’s history of successes and failures. Yet, in the newly settled Simpac system, some unexpected and worrying anomalies begin cropping up, making an urgent expedition to the system necessary: is it the underlying data, the computations, or is some unknown entity tampering with the space colonization program? A race against time ensues as the lives of four strangers begin to converge. While grounded in the social systems aspect, the author posits that the future is likely to be characterized by more biology-based tools than most contemporary science fiction – which most often relies entirely on non-biological hardware in terms of advanced technologies – predicts. The result is an entertaining and skillful blend of thriller and SF, complemented by a nontechnical appendix describing the underlying science.

Objektorientierte und verteilte Lösung von Optimierungsproblemen (Beiträge zur Wirtschaftsinformatik #25)
by Frank Josef BrüggemannReale Optimierungsprobleme erfordern die Berechnung hochkomplexer Computermodelle. Die dazu notwendige Rechenleistung kann kostengünstig durch Workstation-Cluster bereitgestellt werden, die die Leistungsfähigkeit von Mini-Supercomputern erreichen und oft nur zu einem geringen Teil ausgelastet sind. Im Buch wird auf Basis von OMT ein objektorientierter Ansatz für die verteilte Lösung von Optimierungsproblemen entwickelt und in ein Prototyp-System umgesetzt. Der in C++ implementierte Prototyp verfügt über eine graphische Oberfläche zur Steuerung der Optimierungsrechnung und zeigt, wie existierende Softwarepakete aus Fortran oder C in die verteilte Berechnung integriert werden können.
Verläßliche IT-Systeme: Proceedings der GI-Fachtagung VIS ’95 (DuD-Fachbeiträge)
by Hans H. Brüggemann Waltraud Gerhardt-HäcklInformationstechnische Systeme sind heute aus dem Leben nicht mehr wegzudenken. In relativ kurzer Zeit und in unterschiedlichsten Lebensbereichen hat der Gebrauch von IT-Systemen zu Abhängigkeiten zwischen diesen Systemen und dem erwarteten Funktionieren der automatisierten Prozesse geführt. Diese Wechselwirkungen sind verschieden groß, abhängig von den Eigenschaften des betreffenden IT-Systems, der Umgebung des IT-Systems sowie der Art und Intensität seines Gebrauchs. Ein Bewertungsmaßstab, den insbesondere Benutzer und Betreiber eines IT Systems an die erwartungsgemäße Unterstützung der automatisierten Prozesse anlegen, wird durch den Begriff Verläßlichkeit charakterisiert. Verläßlichkeit umfaßt ein Bündel von Systemeigenschaften, die über die klassischen Sicherheitsanforderungen der Verfügbarkeit, Integrität und Vertraulichkeit hinausgehen. Hinzu treten mindestens noch Forderungen bezüglich der Durchschaubarkeit der Wirkungen einer Benutzer-Aktion und umgekehrt der Rückverfolgbarkeit einer Wirkung zu den auslösenden Aktionen und Personen. Ein umfassendes Kriterium ist die Verantwortbarkeit der Nutzung eines IT Systems unter verschiedenen Aspekten wie z.B. der Wahrung von Persönlichkeitsrechten, sicherheitstechnischer Anforderungen oder der Realisierung von Unternehrnenszielen. Verläßlichkeitskriterien sind ein Schlüssel für das Vertrauen, das Benutzer und Betreiber in technische Systeme setzen. Sie sind damit zu Akzeptanzkriterien für technische Systeme geworden. Verläßlichkeitskriterien sowie Methoden und Techniken zur Durchsetzung von Verläßlichkeit sind bisher meist im eingeschränkten Kontext der Systemsicherheit diskutiert worden. Verläßlichkeit verlangt aber nicht nur Schutz vor unberechtigten Zugriffen auf Daten oder Funktionen, sondern z.B. auch die (mathematisch) beweisbare oder die (technisch) garantierbare Funktionalität eines Systems.

Internet Histories
by Niels Brügger Gerard Goggin Ian Milligan Valérie SchaferIn 2017, the new journal Internet Histories was founded. As part of the process of defining a new field, the journal editors approached leading scholars in this dynamic, interdisciplinary area. This book is thus a collection of eighteen short thought-provoking pieces, inviting discussion about Internet histories. They raise and suggest current and future issues in the scholarship, as well as exploring the challenges, opportunities, and tensions that underpin the research terrain. The book explores cultural, political, social, economic, and industrial dynamics, all part of a distinctive historiographical and theoretical approach which underpins this emerging field.The international specialists reflect upon the scholarly scene, laying out the field’s research successes to date, as well as suggest the future possibilities that lie ahead in the field of Internet histories. While the emphasis is on researcher perspectives, interviews with leading luminaries of the Internet’s development are also provided. As histories of the Internet become increasingly important, Internet Histories is a useful roadmap for those contemplating how we can write such works. One cannot write many histories of the 1990s or later without thinking of digital media – and we hope that Internet Histories will be an invaluable resource for such studies. This book was originally published as the first issue of the Internet Histories journal.
The Historical Web and Digital Humanities: The Case of National Web Domains (Digital Research In The Arts And Humanities Ser.)
by Niels Brügger Ditte LaursenThe Historical Web and Digital Humanities fosters discussions between the Digital Humanities and web archive studies by focussing on one of the largest entities of the web, namely national and transnational web domains such as the British, French, or European web. With a view to investigating whether, and how, web studies and web historiography can inform and contribute to the Digital Humanities, this volume contains a number of case studies and methodological and theoretical discussions that both illustrate the potential of studying the web, in this case national web domains, and provide an insight into the challenges associated with doing so. Commentary on and possible solutions to these challenges are debated within the chapters and each one contributes in its own way to a web history in the making that acknowledges the specificities of the archived web. The Historical Web and Digital Humanities will be essential reading for those with an interest in how the past of the web can be studied, as well as how Big Data approaches can be applied to the archived web. As a result, this volume will appeal to academics and students working and studying in the fields of Digital Humanities, internet and media studies, history, cultural studies, and communication.

Der IT Business Case: Kosten erfassen und analysieren - Nutzen erkennen und quantifizieren - Wirtschaftlichkeit nachweisen und realisieren (Xpert.press)
by Ralf BruggerObwohl sich das Potential der Informationstechnologie in den letzten Ja- zehnten vervielfacht hat und dadurch die Informatik zweifelsfrei an Bed- tung gewonnen hat, hat sich eines nicht verändert – die Tatsache, dass die Informatik primär als Kostenverursacher wahrgenommen wird. Wenn es um die Kosten geht, hat die Informatik ein angeschlagenes Image. Viele Unternehmenslenker assoziieren Informationstechnologie mit einem - durchsichtigen „Technologie-Schwamm“, der problemlos in der Lage ist, jedes auch noch so hohe Budget zu absorbieren – wobei der Rückfluss in den meisten Fällen ungewiss ist. Die Informatik begegnet diesem Bild, indem sie der Unternehmensf- rung eine zu eindimensionale Sichtweise vorwirft und auf die qualitativen Aspekte ihrer Arbeit verweist. So ist beispielsweise die Rede von „in- grierter Information“, „schnellerer Verfügbarkeit“, „höherer Automatis- rung“, „effizienteren Prozessen“, „größerer Flexibilität“, „stärkerer In- gration“, „einheitlicher Architektur“, „erhöhter Transparenz“ und „weniger Medienbrüchen“. Diese Argumentationsstrategie trägt jedoch nicht wirklich dazu bei, die an die Informatik gerichteten Vorwürfe der intransparenten Wertgener- rung zu entkräften. Die qualitativen Merkmale werden von der Geschäf- leitung kaum wahrgenommen. Die schwache Akzeptanz von qualitativen Auswirkungen beruht zum einen auf der mangelnden Transparenz dieser Eigenschaften. Ein ursächlicher Zusammenhang zwischen den investierten Ressourcen (sowohl in finanzieller, als auch in personeller Hinsicht) und den erzielten Qualitätsmerkmalen ist nur schwer ersichtlich. Noch sch- rer nachvollziehbar ist gar der Einfluss von Informatik-Ausgaben auf das Unternehmensresultat. Doch was schlussendlich zählt, ist nun einmal das Geschäftsergebnis – und dieses wird zunächst durch die IT-Kosten - schmälert.
Der IT Business Case: Kosten erfassen und analysieren - Nutzen erkennen und quantifizieren - Wirtschaftlichkeit nachweisen und realisieren (Xpert.press)
by Ralf BruggerWie jede Unternehmensfunktion muss auch die Informationstechnik (IT) ihren finanziellen Wertbeitrag nachweisen. Dafür bedarf es eines Brückenschlags zwischen Grundsätzen des finanziellen Managements einerseits und Merkmalen der Informationstechnologie andererseits. Diese Verbindung stellt der Autor her, indem er IT-orientiertes Finanzwissen vermittelt und aufzeigt, wie die Forderung nach einer wirtschaftlichen Positionierung der IT in die Tat umgesetzt werden kann. Die 2. Auflage wurde korrigiert und um das Thema Opportunitätskosten erweitert.
