نگهداری و تکامل مؤثر نرم‌افزار: رویکردی مبتنی بر استفاده مجدد

with Software Maintenance Costs Averaging 50% Of Total Computing Costs, It Is Necessary To Have An Effective Maintenance Program In Place. Aging Legacy Systems, For Example, Pose An Especially Rough Challenge As Veteran Programmers Retire And Their Successors Are Left To Figure Out How The Systems Operate. This Book Explores Program Analyzers, Reverse Engineering Tools, And Reengineering Tools In-depth And Explains The Best Ways To Deploy Them. It Also Discusses Using Xml-based Tools, The Roles Of Software Components, Object Technology, And Metaprogramming In Improving Systems Maintenance, As Well As How To Align Software With Business Goals Through Strategic Maintenance. "Effective Software Maintenance and Evolution: A Reuse-Based Approach examines various methods and the issues that can arise. The first part of the book concentrates on conventional methods for software maintenance. It discusses static program analysis and reverse engineering methods, and model-based design, a technique that can ease anticipated changes, as well as software configuration management tools." "Certain problems related to change remain inherently difficult to address with conventional methods. As a result, the second part of the book describes a novel approach called "mixed-strategy." Mixed-strategy exploits similarities in software and in patterns of evolutionary changes, simplifying software maintenance and evolution. Mixed-strategy program representation comprises code along with information about program design and changes that occurred to software over time. It is non-redundant, easy to work with, human-readable, and amenable to automation."--BOOK JACKET Explores program analyzers, reverse engineering tools, and re engineering tools and explains the best ways to deploy them.
