توسعه پایگاه داده مبتنی بر آزمون: باز کردن چابکی (سری Lean-Agile اهداف شبکه)

The practice of Test-Driven Development (TDD) has helped thousands of software developers improve quality, agility, productivity, and speed. In __**Test-Driven Database Development**__ , Max Guernsey, III shows how to adapt TDD to achieve the same powerful benefits in database design and development. Guernsey first explains why TDD offers so much potential to database practitioners, and how to overcome obstacles such as the lack of conventional “testable classes.” You’ll learn how to use “classes of databases” to manage change more effectively; how to define testable database behaviors; how to maximize long-term maintainability by limiting a database’s current scope; and how to use “emergent design” to simplify future expansion. Building on this foundation, the author guides you through implementing modern TDD processes and database refactoring. He presents practical techniques for improving legacy databases; for deviating from strict TDD when necessary; and for adapting TDD to applications that persist data in file systems, XML, or serialized objects. Guernsey shows how to • Build a simple infrastructure to track and standardize scripts and databases• Define a sustainable TDD process for database design• Safely change a design without losing data• Design new databases that are lighter, leaner, simpler, more testable, and easier to change• Reduce design costs by eliminating duplication• Gradually bring the benefits of TDD, agility, and modern design to legacy databases• Remediate errors that find their way into database designs• Isolate behaviors and avoid unwanted dependencies that cause tests to fail With this book as a guide, you will learn how to apply the proven practice of TDD to your database needs, and organize and optimize your organization’s data for a significant competitive advantage. __**Test-Driven Database Development**__ __is the newest title in the highly respected NetObjectives Lean-Agile Series.__

Design and build truly agile databases that can be changed frequently, safely, and painlessly, no matter how much existing data they must manage! With this book, you'll finally get past old-fashioned batch-and-queue database development, and construct a truly agile database development environment that works! Pioneering agile database expert Max Guernsey III combines a complete foundation of theoretical knowledge with concrete examples and real solutions to the impediments that have prevented database developers from going agile. Guernsey especially shows how to adapt agile principles to handle massive amounts of existing data that makes database change more difficult.

Test-Driven Database Development is based on the training curricula for the author's pioneering NetObjectives course, Database Agility Online Training, which has helped hundreds of database professionals master critical technical skills for designing databases that can be changed frequently, safely, and painlessly. Reflecting his immense experience with agile database development, Guernsey helps you make sure all databases and data remain consistent in agile environments; ensure stability no matter how fast databases change; and test-drive designs to find and fix errors before they're baked into the system. This book will be an invaluable resource for virtually every database analyst and DBA in agile organizations; for many database team, project, and group managers; and for even more agile development team members in organizations that rely on large and complex databases.
