Download or read book Modernizing Legacy Systems written by Robert C. Seacord and published by Addison-Wesley Professional. This book was released on 2003 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Model Driven Software Migration A Methodology written by Christian Wagner and published by Springer Science & Business Media. This book was released on 2014-03-10 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Legacy System Wrapping for Department of Defense Information System Modernization written by and published by . This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document explains the activities, benefits, problems, and issues in using the object-oriented technique of software wrapping to support the migration from legacy information systems to modernized systems. DoD legacy systems have obsolete technologies such as closed systems, stovepipe design, and outmoded programming languages or database systems. Software wrapping is used to create an interface around data, individual modules, subsystems, or whole systems, allowing access to the entities in the original system. Examples of wrapping implementation and guidelines, using the Ada programming language (Ada 83), are given for functions or subprograms originally written in the Cobol, C, Fortran, and Assembler. In addition, software wrapping is analyzed in the broader context of alternative migration strategies for a whole system. The unite-and-conquer strategy appears to be better suited to software wrapping, using a unified object model throughout progressive stages of migration, as compared to the other three strategies (divide-and-conquer, divide-and-wrap, one-short-rebuild).

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.
