Businesses inevitably face a critical choice in the design and maintenance of their software systems: Dismantle older systems and completely replace them, or incrementally modernize existing systems. Many businesses choose the latter course, seeking to maximize their existing investment and preserve valuable business knowledge, while adapting to rapidly evolving technologies. "Modernizing Legacy Systems" is a much-needed guide, showing how to implement a successful modernization strategy and describing specifically a risk-managed, incremental approach--one that encompasses changes in software technologies, engineering processes, and business practices.
Key topics include: Making a case for modernizationUnderstanding requirements and constraintsMaintaining performance, data integrity, and securityDesigning and deploying the target architectureMigrating code and data Estimating costsPlanning the modernization effort
For every topic, this book presents current standards and available products that support legacy system modernization. In addition, a large retail-supply-system case study--a system written in COBOL being modernized to one based on the J2EE architecture--runs throughout this book to demonstrate a real-world legacysystem modernization effort.
