Portable wireless mobile computing is the ability to retrieve information from the main computer system and/or repository of information on a wireless device at anytime and anywhere. An obvious plus here is the ability to also enter or update information on those main computer systems remotely via our wireless device. This gives us all the freedom to theoretically manipulate all information from afar.

The specific type of wireless devices used in our portable wireless mobile architecture is the Personal Digital Assistant, better known as the PDA. The usage of these types of devices is growing at an alarming rate. In the next five years, most cellular telephones will have Internet capabilities, and a large number of individuals will be porting a PDA of some sort.

The goal of this book is to introduce to you, the reader, how to build databases on personal digital devices to be used with PDA applications. Of course, we also try to show how to build PDA applications to use the data within the database.

The focus of this book is effective databases for text and document management inclusive of new and enhanced techniques, methods, theories and practices. The research contained in these chapters is of particular significance to researchers and practitioners alike because of the rapid pace at which the Internet and related technologies are changing our world. Already there is a vast amount of data stored in local databases and Web pages (HTML, DHTML, XML and other markup language documents). In order to take advantage of this wealth of knowledge, we need to develop effective ways of extracting, retrieving and managing the data. In addition, advances in both database and Web technologies require innovative ways of dealing with data in terms of syntactic and semantic representation, integrity, consistency, performance and security.

One of the objectives of this book is to disseminate research that is based on existing Web and database technologies for improved information extraction and retrieval capabilities. Another important objective is the compilation of international efforts in database systems, and text and document management in order to share the innovation and research advances being done at a global level.

Beginning VB 2008 Databases teaches you everything you need to know about relational databases, SQL, and ADO.NET 2.0, giving you a sound start in developing console and Windows database applications. The book also includes chapters on the new SQL Server XML data type and the forthcoming LINQ enhancements to the next version of Visual Basic.

In addition to teaching you database basics like using SQL to communicate with databases, this book provides you with detailed, code-practical techniques to access data in Visual Basic 2008 across a range of coding situations. Code-heavy and full of practical detail, this book has been fully revised and upgraded for .NET 3.5 and offers you the best contemporary practice in this core programming area, so that you’ll find yourself using it in nearly all your .NET projects.

• Provides step-by-step instructions on how to install and configure necessary tools
• Presents all essential SQL query and update concepts and syntax, so you don’t need prior familiarity with relational databases or SQL
• Describes how to use ADO.NET transactions, exceptions, and events
• Covers ADO.NET features for handling XML, text, and binary data within a Visual Basic 2008 context
• Explains all concepts through straightforward code examples

This guide is an ideal introduction to Hibernate, the framework that lets Java developers work with information from a relational database easily and efficiently. Databases are a very different world than Java objects, and with Hibernate, bridging them is significantly easier. This new edition lets you explore the system, from download and configuration through a series of projects that demonstrate how to accomplish a variety of practical goals.

Harnessing Hibernate is an ideal introduction to the popular framework that lets Java developers work with information from a relational database easily and efficiently. Databases are a very different world than Java objects, and they often involve people with different skills and specializations. With Hibernate, bridging these two worlds is significantly easier, and with this book, you can get up to speed with Hibernate quickly.

Rather than present you with another reference, Harnessing Hibernate lets you explore the system, from download and configuration through a series of projects that demonstrate how to accomplish a variety of practical goals. The new edition of this concise guide walks you through Hibernate's primary features, which include mapping from Java classes to database tables, and from Java data types to SQL data types. You will also learn about Hibernate's data query and retrieval facilities, and much more.

It hasn't taken Web developers long to discover that when it comes to creating dynamic, database-driven Web sites, MySQL and PHP provide a winning open source combination. Add this book to the mix, and there's no limit to the powerful, interactive Web sites that developers can create. With step-by-step instructions, complete scripts, and expert tips to guide readers, veteran author and database designer Larry Ullman gets right down to business: After grounding readers with separate discussions of first the scripting language (PHP) and then the database program (MySQL), he goes on to cover security, sessions and cookies, and using additional Web tools, with several sections devoted to creating sample applications. This guide is indispensable for intermediate- to advanced level Web designers who want to replace their static sites with something dynamic. In this edition, the bulk of the new material covers the latest versions of both technologies: PHP 6 (due out in 2008) and MySQL 5 (available now). The book's publication date is likely to beat the official release of PHP 6, making it one of the first books available on the subject.
