Object-Oriented eBooks

Foreword by Kent Beck "The authors of this book have led a revolution in the craft of programming by controlling the environment in which software grows.' --Ward Cunningham 'At last, a book suffused with code that exposes the deep symbiosis between TDD and OOD. This one's a keeper.' --Robert C. Martin 'If you want to be an expert in the state of the art in TDD, you need to understand the ideas in this book.'--Michael Feathers Test-Driven Development (TDD) is now an established technique for delivering better software faster. TDD is based on a simple idea: Write tests for your code before you write the code itself. However, this "simple" idea takes skill and judgment to do well. Now there's a practical guide to TDD that takes...

If you need to create or use formal descriptions of XML vocabularies, the W3C's XML Schema offers a powerful set of tools for defining acceptable document structures and content. An alternative to DTDs as the way to describe and validate data in an XML environment, XML Schema enables developers to create precise descriptions with a richer set of datatypes?such as booleans, numbers, currencies, dates and times?that are essential for today?s applications.Schemas are powerful, but that power comes with substantial complexity. This concise book explains the ins and outs of XML Schema, including design choices, best practices, and limitations. Particularly valuable are discussions of how the type structures fit with existing database and object-oriented p...
