Book Description
A business history of the software industry from the days of custom programming to the age of mass-market software and video games. From its first glimmerings in the 1950s, the software industry has evolved to become the fourth largest industrial sector of the US economy. Starting with a handful of software contractors who produced specialized programs for the few existing machines, the industry grew to include producers of corporate software packages and then makers of mass-market products and recreational software. This book tells the story of each of these types of firm, focusing on the products they developed, the business models they followed, and the markets they served. By describing the breadth of this industry, Martin Campbell-Kelly corrects the popular misconception that one firm is at the center of the software universe. He also tells the story of lucrative software products such as IBM's CICS and SAP's R/3, which, though little known to the general public, lie at the heart of today's information infrastructure.With its wealth of industry data and its thoughtful judgments, this book will become a starting point for all future investigations of this fundamental component of computer history.
Conception d'un système de gestion de bases de données réparties
Author: Stefano SpaccapietraPublisher: FeniXX
ISBN: 2307360301
Category : Computers
Languages : fr
Pages : 162
Book Description
Au cours des prochaines années, l'utilisation des systèmes informatiques répartis deviendra une des composantes essentielles de notre société. Le succès de leurs applications dépendra, étroitement, de la conception des systèmes de gestion des bases de données, réparties (SGBDR) en vue de leur bonne adaptation aux besoins des utilisateurs. C'est pourquoi les utilisateurs et les informaticiens doivent réfléchir, dès maintenant, aux problèmes que pose la conception de ces nouveaux systèmes. Le but de ce livre, actuellement unique en son genre en langue française, est d'aider les uns et les autres dans cette tâche. Il propose une analyse détaillée et progressive, en vue d'identifier les problèmes et de choisir les solutions, qui jalonnent le processus de la conception d'un SGBDR. Il permet de comprendre les principes de base de ces systèmes, et d'en connaître, précisément et complètement, les possibilités fonctionnelles. Cette analyse privilégie, en effet, l'étude des interactions entre les besoins des utilisateurs et les spécifications du système : c'est dans la conformité de celles-ci à ceux-là, plus que dans les processus techniques, que se joue l'avenir de cette informatique. L'ouvrage s'adresse donc à la fois aux utilisateurs, auxquels la clarté de la rédaction le rend facilement accessible, aux ingénieurs qui ont à évaluer l'apport de ces nouvelles techniques, aux informaticiens, qui auront à concevoir des systèmes répartis, et aux chercheurs qui veulent s'initier à ce domaine de l'informatique. Les principaux points abordés par l'auteur sont les suivants : - pourquoi recourir à l'informatique répartie ? - qu'est-ce qu'un système de gestion de bases de données réparties ? - définition de l'environnement réparti et de l'environnement local ; - définition du schéma global d'un SGBDR ; - la répartition des données ; - l'architecture du système, les différentes fonctions ; - les utilisateurs face à la répartition. L'ouvrage est complété par deux chapitres, l'un sur les tendances actuelles de la recherche, l'autre sur les conséquences de l'informatique répartie sur la vie des entreprises, sur les libertés individuelles et sur le développement de l'informatique.

Local Applications of the Ecological Approach To Human-Machine Systems
Author: Peter A. HancockPublisher: CRC Press
ISBN: 1351434837
Category : Technology & Engineering
Languages : en
Pages : 335
Book Description
There is a growing consensus in the human factors/ergonomics community that human factors research has had little impact on significant applied problems. Some have suggested that the problem lies in the fact that much HF/E research has been based on the wrong type of psychology, an information processing view of psychology that is reductionistic and context-free. Ecological psychology offers a viable alternative, presenting a richer view of human behavior that is holistic and contextualized. The papers presented in these two volumes show the conceptual impact that ecological psychology can have on HF/E, as well as presenting a number of specific examples illustrating the ecological approach to human-machine systems. It is the first collection of papers that explicitly draws a connection between these two fields. While work in this area is only just beginning, the evidence available suggests that taking an ecological approach to human factors/ergonomics helps bridge the existing gap between basic research and applied problems.
Faecal Sludge Management
Author: Linda StrandePublisher: IWA Publishing
ISBN: 1780404735
Category : Technology & Engineering
Languages : en
Pages : 428
Book Description
It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
