There is no more authoritative pair of authors on Querying XML than Jim Melton and Stephen Buxton. Best of all, as readers of Jim's other books know, his informal writing style will teach you what you need to know about this complex subject without giving you a headache. If you need a comprehensive and accessible overview of Querying XML, this is the book you have been waiting for.
This manual describes Oracle XML DB, and how it stores, generates, manipulates,
manages, and queries XML in the database using Oracle XML DB.
After introducing you to the heart of Oracle XML DB, namely the XMLType
framework and Oracle XML DB repository, the manual provides a brief introduction to
design criteria to consider when planning your Oracle XML DB application. It
provides examples of how and where you can use Oracle XML DB.
The perfect resource for beginning XML programmers, this guidebook clearly shows you what XML is, how to use it, and what technologies surround it. The authors build on the strengths of previous editions while covering the latest changes in the XML landscape such as XQuery, RSS and Atom, and Ajax. The most recent specifications are presented along with best practices to follow when developing XML solutions.
The fourth edition will help you quickly progress from XML basics to more advanced programming techniques.
XQuery can be a challenging topic to teach. There is only enough time to cover
what it is, what it can do, and its basic syntax, but not in any depth. This
module leaves the detailed coverage of XQuery for later courses. Just as Course
1913A, Exchanging and Transforming Data Using XML and XSLT, is a fiveday
course on Extensible Stylesheet Language Transformations (XSLT), it is
possible to devote a full five-day course to XQuery after it is fully specified and
achieves W3C Recommendation status.
This lesson introduces XPath and the reasons for using it. To understand the
rest of the module, the students must understand how XPath expressions are a
navigational language for XML documents. Stress that XPath is an XML
language that provides access to nodes and their contents, wherever the nodes
are located in an XML document.
Cái bộ (Set of) Nodes do XPath trả về được gọi là Collection. Thông thường trong lập trình, từ "Collection" được dùng để nói đến một tập hợp các objects đồng loại. Ta có thể lần lượt đi qua (iterate through) các objects trong một Collection nhưng không được bảo đảm thứ tự của chúng, tức là gặp object nào trước hay object nào sau.
This reference describes Oracle XML Developer's Kits (XDK) and Oracle XML DB
APIs. It primarily lists the syntax of functions, methods, and procedures associated
with these APIs.This guide is intended for developers building XML applications in Oracle.
To use this document, you need a basic understanding of object-oriented
programming concepts, familiarity with Structured Query Language (SQL), and
working knowledge of application development using either C or C++.
LINQ is the project name for a set of extensions to the .NET Framework that provide a generic approach to querying data from different data sources. LINQ will premier in Visual Studio 2008, and will become the next must–have skill for .NET developers. For more information about LINQ, you can check out the author’s portal at

[ Team LiB ] Recipe 8.10 Filling a DataSet Using an XML Template Query Problem You have an XML template query that you need to use from ADO.NET. You need to fill a DataSet using an XML template query. Solution Use an XML template query to fill a DataSet using the SQLXML Managed Classes.
We present an implemented XML data model and a new, simpliﬁed query language for multi-level annotated corpora. The new query language involves automatic conversion of queries into the underlying, more complicated MMAXQL query language. It supports queries for sequential and hierarchical, but also associative (e.g. coreferential) relations. The simpliﬁed query language has been designed with non-expert users in mind.
Giới thiệu Trong bài đầu tiên của loạt bài này, Điều chỉnh SQL với Optim Query Tuner, Phần 1: Tìm hiểu về các đường dẫn truy cập, đã giới thiệu khái niệm về một đường dẫn truy cập. Với một câu lệnh SQL cụ thể, thường có nhiều sự lựa chọn đường dẫn truy cập, và các đường dẫn truy cập khác nhau thường có đặc điểm hiệu năng khác nhau.
After completing this unit, you should be able to: List the characteristics of an XML document that help determine the right type of database, define and describe content management databases, compare relational database structures to XML document structures, list the limitations of relational data tables with structured data, define and describe what Object-Oriented databases provide, describe the status of XML-based queries.
Bài giảng Lập trình hướng đối tượng 2: Language Integrated Query (LINQ) gồm có những nội dung chính sau: Giới thiệu LINQ, LINQ to Object, LINQ to XML, LINQ to ADO.NET. Mời các bạn cùng tham khảo để nắm bắt các nội dung chi tiết.
In this paper we describe the X-TRACT workbench, which enables efficient termbased querying against a domain-specific literature corpus. Its main aim is to aid domain specialists in locating and extracting new knowledge from scientific literature corpora. Before querying, a corpus is automatically terminologically analysed by the ATRACT system, which performs terminology recognition based on the C/NCvalue method enhanced by incorporation of term variation handling.
Chapter 10 describes the XML language, and then presents different ways of expressing queries on data represented in XML,and transforming XMLdata from one form to another. This chapter presents the following content: Structure of XML data, XML document schema, querying and transformation, application program interfaces to XML, storage of XML data, XML applications.
In the previous chapter, I introduced you to LINQ. I provided some examples to whet your appetite,
and shared some premature tips. You may be perplexed though by some of the syntax. If so, it is
probably because the C# you witnessed in that chapter is new and improved. The reason for the C#
language upgrade is that C# 2.0 just didn’t have the muscle to pull off LINQ. In this chapter, I introduce
you to the more powerful C# 3.0.
Oracle Database Application Developer's Guide - Object-Relational Features describes
how to use the object-relational features of the Oracle Server, 10g Release 1 (10.1).
Information in this guide applies to versions of the Oracle Server that run on all
platforms, and does not include system-specific information. Oracle Database Application Developer's Guide - Object-Relational Features is intended
for programmers developing new applications or converting existing applications
to run in the Oracle environment.
creating tables with XML columns, and allows declaring XML variables and using them as parameters and return values. XQuery is a W3C-recommended language created to query and format XML documents. XQuery can be used to query XML documents just like a SQL query is used to retrieve information from relational tables. The XML data type implements a limited subset of the XQuery speciﬁcation and a T-SQL query can use XQuery to retrieve information from XML columns or variables.
