Refactoring has proven its value in a wide
range of development projects–helping software professionals improve system
designs, maintainability, extensibility, and performance. Now, for the first
time, leading agile methodologist Scott Ambler and renowned consultant
Pramodkumar Sadalage introduce powerful refactoring techniques specifically
designed for database systems.
Ambler and Sadalage demonstrate how small
changes to table structures, data, stored procedures, and triggers can
significantly enhance virtually any database design–without changing
semantics. You’ll learn how to evolve database schemas in step with source
code–and become far more effective in projects relying on iterative, agile
methodologies.
This comprehensive guide and reference helps
you overcome the practical obstacles to refactoring real-world databases by
covering every fundamental concept underlying database refactoring. Using
start-to-finish examples, the authors walk you through refactoring simple
standalone database applications as well as sophisticated multi-application
scenarios. You’ll master every task involved in refactoring database schemas,
and discover best practices for deploying refactorings in even the most
complex production environments.
The second half of this book systematically
covers five major categories of database refactorings. You’ll learn how to use
refactoring to enhance database structure, data quality, and referential
integrity; and how to refactor both architectures and methods. This book
provides an extensive set of examples built with Oracle and Java and easily
adaptable for other languages, such as C#, C++, or VB.NET, and other
databases, such as DB2, SQL Server, MySQL, and Sybase.
Using this book’s techniques and examples, you can reduce waste, rework,
risk, and cost–and build database systems capable of evolving smoothly, far
into the future.
