Desde hace décadas que el mantenimiento y la evolución de los sistemas de información son una de las principales fuentes de preocupación de los responsables y directivos de las organizaciones, que ven cómo el presupuesto dedicado a estas tareas puede superar el 80% del total de los recursos, mermando la posibilidad del desarrollo de nuevos sistemas e imposibilitando la prestación de nuevos servicios. Actualmente, la transformación digital ha enfatizado aún más la importancia de la gestión y evolución de los sistemas heredados (legacy), ya que resulta muchas veces casi imposible adaptar el software existente a nuevos requisitos o cambios tecnológicos En este libro se presentan de forma clara los conceptos fundamentales relacionados con el mantenimiento y la evolución de los sistemas de información, y se ofrece un tratamiento sistemático de los estándares internacionales relacionados con el proceso de mantenimiento y la mantenibilidad del software. Además, se proponen varias metodologías, contrastadas en decenas de proyectos realizados a lo largo de más de 20 años para abordar el mantenimiento de los sistemas de información, analizando algunas técnicas y herramientas que pueden facilitar la evolución del software. A lo largo de esta obra se ha combinado el rigor académico con la experiencia práctica, proporcionando a sus lectores una panorámica actual y completa sobre la problemática asociada al mantenimiento y la evolución de los sistemas de información.
Management Information Systems provides comprehensive and integrative coverage of essential new technologies, information system applications, and their impact on business models and managerial decision-making in an exciting and interactive manner. The twelfth edition focuses on the major changes that have been made in information technology over the past two years, and includes new opening, closing, and Interactive Session cases.
Este libro presenta de forma clara y resumida los conceptos fundamentales relacionados con el proceso de mantenimiento del software, así como un tratamiento sistemático de los estándares internacionales y de las herramientas relacionadas con el mantenimiento. Así mismo, se exponen los aspectos más significativos de la externalización y del outsourcing del mantenimiento, junto con soluciones metodológicas y varios casos reales de mantenimiento de software.
Includes articles in topic areas such as autonomic computing, operating system architectures, and open source software technologies and applications.
This book contains the best papers of the First International Conference on Software and Data Technologies (ICSOFT 2006), organized by the Institute for Systems and Technologies of Information, Communication and Control (INSTICC) in cooperation with the Object Management Group (OMG). Hosted by the School of Business of the Polytechnic Institute of Setubal, the conference was sponsored by Enterprise Ireland and the Polytechnic Institute of Setúbal. The purpose of ICSOFT 2006 was to bring together researchers and practitioners int- ested in information technology and software development. The conference tracks were “Software Engineering”, “Information Systems and Data Management”, “Programming Languages”, “Distributed and Parallel Systems” and “Knowledge Engineering.” Being crucial for the development of information systems, software and data te- nologies encompass a large number of research topics and applications: from imp- mentation-related issues to more abstract theoretical aspects of software engineering; from databases and data-warehouses to management information systems and kno- edge-base systems; next to that, distributed systems, pervasive computing, data quality and other related topics are included in the scope of this conference. ICSOFT included in its program a panel to discuss the future of software devel- ment, composed by six distinguished world-class researchers. Furthermore, the c- ference program was enriched by a tutorial and six keynote lectures. ICSOFT 2006 received 187 paper submissions from 39 countries in all continents.
The Database and Expert Systems Applications (DEXA) conferences have established themselves as a platform for bringing together researchers and practitioners from various backgrounds and all regions of the world to exchange ideas, experiences and opinions in a friendly and stimulating environment. The papers presented at the conference represent recent developments in the field and important steps towards shaping the future of applied computer science and information systems. DEXA covers a broad field: all aspects of databases, knowledge based systems, knowledge management, web-based systems, information systems, related technologies and their applications. Once again there were a good number of submissions: out of 183 papers that were submitted, the program committee selected 92 to be presented. In the first year of this new millennium DEXA has come back to the United Kingdom, following events in Vienna, Berlin, Valencia, Prague, Athens, London, Zurich, Toulouse, Vienna and Florence. The past decade has seen several revolutionary developments, one of which was the explosion of Internet-related applications in the areas covered by DEXA, developments in which DEXA has played a role and in which DEXA will continue to play a role in its second decade, starting with this conference.
Dispelling much of the folklore surrounding software maintenance, Software Maintenance Success Recipes identifies actionable formulas for success based on in-depth analysis of more than 200 real-world maintenance projects. It details the set of factors that are usually present when effective software maintenance teams do their work and instructs on
Software maintenance, the work done on a software system after it becomes operational, consumes at least half of all technical and management resources expended in the software area. This volume supplies an overview of software maintenance : what it is, how to do it, how to manage it, and trends in current research. The thirty-one papers included are frequently requested from their authors, from hard-to-find sources, cover the foundations of current thinking on this topic, and extend the frontiers of research.
