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.

For almost a hundred years the academic study of migration concentrated on evolving standardised models of migration behaviour based on data from censuses or the registration of births, marriages and deaths. More recently, it has been realised that such models fail to take into account the decision-making behind migration and that better understanding will come from study of the behaviour of individuals as well as aggregate numbers. In this book the imaginative use of alternative sources DS for example, apprentice books, guild and craft records, legal and court documents, diaries and biographies DS gives fresh insights into the processes of movement to reveal much more complex circulatory behaviour than the standard models derived from census and registration sources alone have suggested.The first chapter confronts the issue of rural mobility in post-famine Ireland and is followed by a study centred on Alpine rural families which built impressive networks across pre-industrial Western Europe. Two chapters focus on the particular characteristics of worker groups: mining families of south Lancashire during the period of rapid increase in coal production in the eighteenth century; and the organised mobility of skilled labour in nineteenth-century central Europe. Next, an imaginative and rigorous deployment of the techniques of family reconstruction and record linkage embracing a variety of sources (vital event registers, wills, port books, apprentice records) teases out the migration histories of those who settled in eighteenth-century Liverpool. There are two chapters on female migrant behaviour, drawing attention in the case of eighteenth-century Rheims to the opportunities and restrictions on the life of migrant women at different points in their lifecycles; and showing how poor women struggled to survive in nineteenth-century Dublin. The final chapter uses family histories assembled by numerous genealogists and family historians to challenge the orthodox view of direct stepwise migration from a smaller to a larger town in the urban hierarchy.

To understand why people migrate during periods of modernization, Barbara Anderson contends that one must study the place of origin, since the persons at the origin are the potential migrant population. Using data from the 1897 Imperial Russian Census, the author examines two types of migration: that to an already settled, relatively modern area, such as the major cities; and that to a sparsely populated, relatively traditional area, such as the agricultural frontier. Originally published in 1980. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Mobility and Modernity uses voluminous German data on migrations over the past two centuries to demonstrate why conventional assumptions about the relationship between mobility and modernity must be revised. Thus far the changing total volume of migration has not been traced over a long period for any country. Unique migration registration statistics, both detailed and broadly geographical in coverage, allow the precise plotting of migration rates in Germany since 1820. Steve Hochstadt combines careful quantitative methods, easily understood numerical data, and social analysis based upon broad reading in German social history to show that current beliefs about the direction and timing of changes in German mobility, which have been based on late nineteenth-century anxieties about urbanization and industrialization, do not match the data. Migration rates in Germany rose continuously throughout the nineteenth century, and have fallen during the twentieth century. Mobility, Hochstadt argues, was not an unprecedented accompaniment to industrialization, but a traditional rural response to specific economic changes. Hochstadt's more precise analysis of urban in- and outmigration shows the mechanism of urbanization to have been the migration of families rather than the much greater, but also more circular, migration of single men and women. Hochstadt demonstrates the importance of examining historical behavior, powerfully justifying the methods of historical demography as a path to social understanding. The data and specific conclusions are German, but the methods and reinterpretaion of migration history have much wider application, both to other modern European nations and to currently developing countries. Those who study the modern social history of Europe, the mechanisms that formed urban working classes, and the methods of historical demography will be interested in Hochstadt's work.

Without established design patterns to guide them, developers have had to build distributed systems from scratch, and most of these systems are very unique indeed. Today, the increasing use of containers has paved the way for core distributed system patterns and reusable containerized components. This practical guide presents a collection of repeatable, generic patterns to help make the development of reliable distributed systems far more approachable and efficient. Author Brendan Burns—Director of Engineering at Microsoft Azure—demonstrates how you can adapt existing software design patterns for designing and building reliable distributed applications. Systems engineers and application developers will learn how these long-established patterns provide a common language and framework for dramatically increasing the quality of your system. Understand how patterns and reusable components enable the rapid development of reliable distributed systems Use the side-car, adapter, and ambassador patterns to split your application into a group of containers on a single machine Explore loosely coupled multi-node distributed patterns for replication, scaling, and communication between the components Learn distributed system patterns for large-scale batch data processing covering work-queues, event-based processing, and coordinated workflows

Cloud computing is the most significant technology development of our lifetimes. It has made countless new businesses possible and presents a massive opportunity for large enterprises to innovate like startups and retire decades of technical debt. But making the most of the cloud requires much more from enterprises than just a technology change. Stephen Orban led Dow Jones's journey toward digital agility as their CIO and now leads AWS's Enterprise Strategy function, where he helps leaders from the largest companies in the world transform their businesses. As he demonstrates in this book, enterprises must re-train their people, evolve their processes, and transform their cultures as they move to the cloud. By bringing together his experiences and those of a number of business leaders, Orban shines a light on what works, what doesn't, and how enterprises can transform themselves using the cloud.

Most organizations rely on complex enterprise information systems (EISs) to codify their business practices and collect, process, and analyze business data. These EISs are large, heterogeneous, distributed, constantly evolving, dynamic, long-lived, and mission critical. In other words, they are a complicated system of systems. As features are added to an EIS, new technologies and components are selected and integrated. In many ways, these information systems are to an enterprise what a brain is to the higher species--a complex, poorly understood mass upon which the organism relies for its very existence. To optimize business value, these large, complex systems must be modernized--but where does one begin? This book uses an extensive real-world case study (based on the modernization of a thirty year old retail system) to show how modernizing legacy systems can deliver significant business value to any organization.
