商品描述

Working it's way towards W3C Recommendation status sometime in 2002, the XQuery language and associated specifications are the biggest project to date from the World Wide Web Consortium since it ratified XML in 1998. XQuery is to XML data as SQL is to data in relational databases and more - a single syntax that allows us to specify queries on structured XML data, independent of how and on what platform it is stored, and return the results as XML in a structure of your choosing. It is also one of the first large scale attempts to get the various W3C specifications in line with each other, uniting the XSL, XQuery, and XML Schema working groups in its creation.

Early Adopter XQuery presents the facts about this ambitious new technology, covering its history and development to date, and what changes might occur in the future before it is ratified. We present easy-to-follow introductions to the XQuery language for those already familiar with SQL and XSLT that others can follow too and a look at the early implementations of XQuery that exist around the internet. In particular, we look at .NET and Java classes which you can use to incorporate XQuery into your own work and a basic case study demonstrating how to build your own XQuery engine.

What does this book cover?

The History of XQuery, its predecessors and how to work with the current set of XQuery documents
The XQuery Data Model, Formal Semantics and Use Cases
XQuery from a SQL perspective
XQuery from an XSLT/XML perspective
The current set of XQuery implementations available today, in particular Microsoft's .NET classes for XQuery and FatDog's Java implementation
How to set about building your own XQuery engine

商品描述(中文翻譯)

在2002年，XQuery語言和相關規範正朝著W3C推薦狀態邁進，這是自1998年W3C批准XML以來，該組織迄今為止最大的項目。XQuery對於XML數據的處理，就像SQL對於關聯數據庫中的數據一樣，甚至更多 - 它提供了一種單一的語法，允許我們在結構化的XML數據上指定查詢，獨立於數據存儲的方式和平台，並以您選擇的結構返回結果。它也是W3C規範之間首次大規模嘗試協調一致的項目之一，將XSL、XQuery和XML Schema工作組聯合起來進行創建。

《早期採用者XQuery》介紹了這項雄心勃勃的新技術的歷史和發展情況，以及在正式批准之前可能發生的變化。我們提供了易於理解的XQuery語言介紹，適用於已熟悉SQL和XSLT的人，其他人也可以跟隨。我們還介紹了互聯網上存在的早期XQuery實現，特別是.NET和Java類，您可以使用這些類將XQuery集成到自己的工作中，並提供了一個基本案例研究，演示如何構建自己的XQuery引擎。

本書涵蓋了以下內容：
- XQuery的歷史、前身以及如何使用當前的XQuery文檔集合
- XQuery數據模型、形式語義和使用案例
- 從SQL的角度看XQuery
- 從XSLT/XML的角度看XQuery
- 當前可用的XQuery實現，特別是微軟的.NET XQuery類和FatDog的Java實現
- 如何構建自己的XQuery引擎
