Open Source XML Database Toolkit
An in-depth look at making XML work with database applications Open Source XML Database Toolkit This guide will arm you with the nuts-and-bolts information and tools you'll need to exploit XML's powerful capabilities. Focusing specifically on how XML works with database technologies-including relational and object-oriented databases-the book provides clear technical coverage of the key issues involved with storing XML in databases and using databases with XML applications. Expert Liam Quin first introduces you to the main concepts of XML and then reveals how to work with this technology. He offers helpful tips and techniques to show you how to move data stored in relational databases in and out of an XML application. You'll also learn how to store XML documents in a database, find and use the best XML database tools and applications, and store links in a database for metadata access. You'll also gain a better understanding of W3C specifications for XQL, XSL, Xlink, and Xpointer. Programmers, Web developers, and technical managers who need to extract database contents as XML or store XML in a database will find this book to be an invaluable resource. This book concentrates on techniques rather than specific tools, but mentions a wide range of software, both commercial and open source, including: * FreeBSD, Solaris, and Linux * MySQL * XT and other XML processors * Apache * Oracle * SoftQuad XMetal and other XML editing software * Object Design's ObjectStore The companion Web site at www.wiley.com/compbooks/quin features: * Additional resources * Utilities * Examples from the book * Updated information
Relational Database Design and Implementation
Fully revised, updated, and expanded, Relational Database Design and Implementation, Third Edition is the most lucid and effective introduction to the subject available for IT/IS professionals interested in honing their skills in database design, implementation, and administration. This book provides the conceptual and practical information necessary to develop a design and management scheme that ensures data accuracy and user satisfaction while optimizing performance, regardless of experience level or choice of DBMS.The book begins by reviewing basic concepts of databases and database design, then briefly reviews the SQL one would use to create databases. Topics such as the relational data model, normalization, data entities and Codd's Rules (and why they are important) are covered clearly and concisely but without resorting to "Dummies"-style talking down to the reader.Supporting the book's step-by-step instruction are three NEW case studies illustrating database planning, analysis, design, and management practices. In addition to these real-world examples, which include object-relational design techniques, an entirely NEW section consisting of three chapters is devoted to database implementation and management issues. - Principles needed to understand the basis of good relational database design and implementation practices - Examples to illustrate core concepts for enhanced comprehension and to put the book's practical instruction to work - Methods for tailoring DB design to the environment in which the database will run and the uses to which it will be put - Design approaches that ensure data accuracy and consistency - Examples of how design can inhibit or boost database application performance - Object-relational design techniques, benefits, and examples - Instructions on how to choose and use a normalization technique - Guidelines for understanding and applying Codd's rules - Tools to implement a relational design using SQL - Techniques for using CASE tools for database design
Technology-Enhanced Systems and Tools for Collaborative Learning Scaffolding
Technology-Enhanced Systems and Tools for Collaborative Learning Scaffolding is a major research theme in CSCL and CSCW research community. This book presents up-to-date research approaches for developing technology-enhanced systems and tools to support functional online collaborative learning and work settings. It comprises a variety of research topics that span from the study of frameworks and infrastructures that foster collaborative learning and work through the application of different methods (distributed e-learning repositories, content creation and customization, social networks, collaborative ontologies building, and educational games) to the use of personalization and adaptation techniques to support the development of more powerful e-collaboration settings, including methodologies and tools for analyzing students' interactions with the aim to increase students' collaborative behaviors, performance and group organization. Researchers will find in this book the latest trends in these research topics, which gives them the opportunity to deepen further on the above issues and to extend their knowledge to other areas. Academics will find practical insights on how to use conceptual and experimental approaches in their daily tasks. Developers from CSCL community can be inspired and put in practice the proposed models and evaluate them for the specific purposes of their own work and context.
