Proven strategies for maintaining and optimizing legacy code to get the most out of your
existing applications. Examples in C-sharp C++ and Java as well as strategies for better
using the industry standard modeling language: UML 2.0 Addresses the very concrete problems
that programmers face working in the context of large untested code bases Based on successful
classes for Object Mentor the author helps organizations maintain older systems rather than go
to the cost of developing new ones This book provides programmers with the ability to cost
effectively handle common legacy code problems without having to go through the hugely
expensive task of rewriting all existing code. It describes a series of practical strategies
that developers can employ to bring their existing software applications under control. The
author provides useful guidance about how to use these strategies when refactoring or making
functional changes to code bases. One of the book's key points is that it teaches developers to
write tests that can be used to make sure they are not unintentionally changing the application
as they optimize it. Examples are provided in Java C++ and Csharp and the book assumes that
the reader has some knowledge of UML notation. Strategies using UML and code in C++ and Java
primarily while language independent advice will be delivered in side bars and appendices for
language specific users.
