Language-Integrated Query (LINQ) es un conjunto de características presentado en Visual Studio 2008 que agrega capacidades de consulta eficaces a la sintaxis de los lenguajes C# y Visual Basic. LINQ incluye patrones estándar y de fácil aprendizaje para consultar y actualizar datos, y su tecnología se puede extender para utilizar potencialmente cualquier tipo de almacén de datos. Visual Studio incluye ensamblados de proveedores para LINQ que habilitan el uso de LINQ con colecciones de .NET Framework, bases de datos SQL Server, conjuntos de datos de ADO.NET y documentos XML.

This book teaches OO PHP by doing it. If you are a PHP programmer who wants to make the switch to an OO approach, Object-Oriented PHP can ease the transition from procedural to object-oriented programming (OOP). Basic concepts are introduced using simple but useful classes. In short, this book: Brings together information from a variety of sources for a comprehensive overview of OO PHP Explains OO concepts through concrete examples, not in the abstract. Takes a practical and easy-to-understand approach Demonstrates the advantages of OOP rather than just asserting them The classes developed in this book are fully functional and are all available for download at the companion website. This code can be put to work immediately in a variety of situations. The code takes full advantage of the capabilities of PHP 5 but, where possible, a PHP 4 version of the code is also provided, because you don’t always have a choice about where your code is deployed. Additionally, this will ease the transition for anyone ready familiar with OOP under PHP 4.
