This book combines case studies with practical examples of how to implement modernization techniques using Oracle (and partner) products to modernize to the Oracle Platform. The book also weighs the pros and cons of specific modernization use cases. Finally, we explore some of the emerging trends in technology and how they apply to legacy modernization. Legacy system architects, project managers, program managers, developers, database architects and decision makers who own mainframe and heterogeneous systems, and are tasked with modernization will all find this book useful. The book assumes some knowledge of mainframes, J2EE, SOA, and Oracle technologies. The reader should have some background in programming and database design.
