Legacy System

Moving legacy systems into the Web-centered future: an intelligent, step-by-step guideCreates a framework to assess, upgrade, and migrate legacy applications and data structures Leverage your legacy systems for competitive business advantage! Your legacy systems embody core business knowledge that is difficult to enhance-but impossible to replicate. You've made enormous investments in these systems. They work. But they were never designed for today's high-speed, Web-centered business environments. In "Legacy Systems: Transformation Strategies," you'll discover exactly how to maximize the business value of legacy systems as you build the flexible, high-value, component-based architectures you need to stay competitive. Leading IT and business architecture consultant William M. Ulrich explores: Creating an environment that supports legacy transformation: strategies, organizing disciplines, techniques, and toolsMoving incrementally to component architectures: minimizing the risks of deploying J2EE, .NET, and/or Web Services Legacy data and application mining, integration, and transformation 7 myths that surround legacy systems: how they can damage or enrich your business-and what to do about it Transition strategies for the new era: how to move forward without abandoning systems that work The wrong decisions about legacy systems can damage your business-or even destroy it. The right decisions will liberate you to meet tomorrow's business challenges without needless disruption or expense. Make the right decisions: read "Legacy Systems: Transformation Strategies.

A proven Java(TM)-based approach to standardizing and streamlining legacy migration This book focuses on the key challenges developers face when using the Java 2 platform Enterprise Edition (J2EE) to encapsulate legacy applications for delivery in a multi-tier Internet environment. Leading Sun architects Torbjoern Dahlen and Thorbioern Fritzon show how to standardize encapsulation using an integration tier that shields the J2EE elements of an application from the properties and demands of its legacy elements. Using this approach, enterprises can promote reuse, accelerate legacy migration projects, and make the most of their COBOL/mainframe and Java expertise. Above all, they can take portability beyond hardware and operating systems, systematically migrating virtually any legacy system without extensive redesign or reprogramming.Presents a pragmatic approach to domain modeling for legacy application migrationPromotes reuse and portability through a standardized, fine-grained domain object modelShows how to streamline the transformation of domain models to working systemsIntroduces a proven, pattern-based J2EE application architecture for Internet-enabling legacy systemsIncludes superior algorithms for object queries, data cleansing and merging, and artificial XA support Advanced J2EE Platform Development presents detailed examples and sample code, including a start-to-finish case study that demonstrates integration between three different legacy systems.

Legacy system - A legacy system is an existing computer system or application program which continues to be used because the user (typically an organization) does not want to replace or redesign it. Many people use this term to refer to "antiquated" systems.

Legacy code - Legacy code is source code that relates to a no-longer supported or manufactured operating system or other computer system. The term can also mean code inserted into modern software for the purpose of maintaining an older or previously supported feature—for example supporting a serial interface even though most modern systems don't have a serial port.

Stovepipe system - In engineering and computing, a stovepipe system is a legacy system that is an assemblage of inter-related elements that are so tightly bound together that the individual elements cannot be differentiated, upgraded or refactored. The stovepipe system must be maintained until it can be entirely replaced by a new system.

Legacy support - In the field of computing, legacy support is an automated approach to dealing with legacy systems. A computer operating system can detect, install and troubleshoot legacy devices (i.
