Legacy Systems: Transformation Strategies (Paperback)

• Moving legacy systems into the Web-centered future: an intelligent, step-by-step guide
• Creates 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 tools
• Moving 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.
