Today, reliable software systems are the basis of any business or company. The continuous further development of those systems is the central component in software evolution. It requires a huge amount of time- man power- as well as financial resources. The challenges are size, seniority and heterogeneity of those software systems. Christian Wagner addresses software evolution: the inherent problems and uncertainties in the process. He presents a model-driven method which leads to a synchronization between source code and design. As a result the model layer will be the central part in further evolution and source code becomes a by-product. For the first time a model-driven procedure for maintenance and migration of software systems is described. The procedure is composed of a model-driven reengineering and a model-driven migration phase. The application and effectiveness of the procedure are confirmed with a reference implementation applied to four exemplary systems.
The authors use a systems approach to examine contemporary international migration and other types of population flows between countries. They investigate the effect of those flows on both sending and receiving countries in the areas of economic, political, and social links of the countries concerned. This work includes a set of comparative case studies as well of theoretical chapters which will be of interest to demographers, sociologists, economists, social historians, as well as policymakers.
This book explores the norms, practices, and main actors in the EU Migration System of Governance (EUMSG). Bringing a fresh perspective to the analysis of asylum and migration in Europe, the volume unpacks the European Union’s approach to migration and points to the principles and actions of EU member states. Moreover, it explores the EUMSG’s performance through the lenses of three alternative yet coexistent understandings of justice (non-domination, impartiality, and mutual recognition), thereby overcoming a unilateral ethical viewpoint and moving away from the ‘open-closed borders’ debate.
This new dictionary provides over 2,000 clear and concise entries on human geography, covering basic terms and concepts as well as biographies, organisations, and major periods and schools.

This book constitutes the refereed proceedings of the First International Conference on Systems Modelling and Management, ICSMM 2020, planned to be held in Bergen, Norway, in June 2020. Due to the COVID-19 pandemic the conference did not take place physically or virtually. The 10 full papers and 3 short papers were thoroughly reviewed and selected from 19 qualified submissions. The papers are organized according to the following topical sections: verification and validation; applications; methods, techniques and tools.
This book offers a timely and critical exploration of leisure and forced migration from multiple disciplinary perspectives, spanning sociology, gender studies, migration studies and anthropology. It engages with perspectives and experiences that unsettle and oppose dehumanising and infantilising binaries surrounding forced migrants in contemporary society. The book presents cutting edge research addressing three inter-related themes: spaces and temporalities; displaced bodies and intersecting inequalities; voices, praxis and (self)representation. Drawing on and expanding critical leisure studies perspectives on class, gender, sexuality and race/ethnicity, the book spotlights leisure and how it can interrogate and challenge dominant narratives, practices and assumptions on forced migration and lives lived in asylum systems. Furthermore, it contributes to current debates on the scope, relevance and aims of leisure studies within the present, unfolding global scenario. This is an important resource for students and scholars across leisure, sport, gender, sociology, anthropology and migration studies. It is also a valuable read for practitioners, advocates and community organisers addressing issues of forced migration and sanctuary.
This two-volume set LNCS 4277/4278 constitutes the refereed proceedings of 14 international workshops held as part of OTM 2006 in Montpellier, France in October/November 2006. The 191 revised full papers presented were carefully reviewed and selected from a total of 493 submissions to the workshops. The first volume begins with 26 additional revised short or poster papers of the OTM 2006 main conferences.
Companies need to migrate data not only when technology needs to be replaced, but also for consolidation, load balancing, and disaster recovery (DR). Data migration is a critical operation, and this book explains the phases and steps to ensure a smooth migration. Topics range from planning and preparation to execution and validation. The book explains, from a generic standpoint, the appliance-based, storage-based, and host-based techniques that can be used to accomplish the migration. Each method is explained through practical migration scenarios and for various operating systems. This publication addresses the aspects of data migration efforts while focusing on fixed block storage systems in open environment with the IBM® FlashSystem 9100 as the target system. Therefore, the book also emphasizes various migration techniques using the Spectrum Virtualize built-in functions. This document targets storage administrators, storage network administrators, system designers, architects, and IT professionals who design, administer or plan data migrations in large data Centers. The aim is to ensure that you are aware of the current thinking, methods, and products that IBM can make available to you. These items are provided to ensure a data migration process that is as efficient and problem-free as possible. The material presented in this book was developed with versions of the referenced products as of February, 2020.
DoD's Corp. Info. Management initiative was started to save billions of dollars by streamlining operations and deploying standard info. systems to support common business operations. A key part of this initiative is DoD's migration effort which involves replacing its functionally duplicative and inefficient automated info. systems with DoD's best existing info. systems. This report provides info. on the status and progress of DoD's migration effort, and assesses whether DoD has effective controls in place to manage and oversee the initiative. Highlights the implications of the findings as it responds to the investment management requirements of the Clinger-Cohen Act.
