With the XQuery 1.0 standard, you finally have a tool that will make it much easier to search, extract and manipulate information from XML content stored in databases. This in-depth tutorial not only walks you through the XQuery specification, but also teaches you how to program with this widely anticipated query language. XQuery is for query writers who have some knowledge of XML basics, but not necessarily advanced knowledge of XML-related technologies. It can be used both as a tutorial, by reading cover to cover, and as a reference, by using the comprehensive index and appendixes. Either way, you will find the background knowledge in namespaces, schemas, built-in types and regular expressions that is relevant to writing XML queries. This book provides: A high-level overview and quick tour of XQuery Information to write sophisticated queries, without being bogged down by the details of types, namespaces, and schemas Advanced concepts for users who want to take advantage of modularity, namespaces, typing and schemas Guidelines for working with specific types of data, such as numbers, strings, dates, URIs and processing instructions A complete alphabetical reference to the built-in functions and types You will also learn about XQuery's support for filtering, sorting, and grouping data, as well as how to use FLWOR expressions, XPath, and XQuery tools for extracting and combining information. With this book, you will discover how to apply all of these tools to a wide variety of data sources, and how to recombine information from multiple sources into a single final output result. Whether you're coming from SQL, XSLT, or starting from scratch, this carefully paced tutorial takes you through the final 1.0 standard in detail.

SQL Server 2005 Integration Services (SSIS) lets you build high-performance data integration solutions. SSIS solutions wrap sophisticated workflows around tasks that extract, transform, and load (ETL) data from and to a wide variety of data sources. This Short Cut begins with an overview of key SSIS concepts, capabilities, standard workflow and ETL elements, the development environment, execution, deployment, and migration from Data Transformation Services (DTS). Next, you'll see how to apply the concepts you've learned through hands-on examples of common integration scenarios. Once you've finished this Short Cut, you'll have the background and understanding you need to start building your own SSIS integration solutions.

Pro Access 2007M covers the features of Microsoft Access 2007, including working with SharePoint Office Server and customizing Ribbons.

What you'll learn Creating custom menus using RibbonX Get up and running building Visual Basic for Applications Classes Learn about Microsoft Office SharePoint Server and how it fits into Access Working with SQL Server and using the new Microsoft Access 2007 to SQL Server 2005 tools Code examples provided to highlight real-world issues Use Access and .NET to present information via the Internet

This Short Cut introduces you to how SQL injection vulnerabilities work, what makes applications vulnerable, and how to protect them. It helps you find your vulnerabilities with analysis and testing tools and describes simple approaches for fixing them in the most popular web-programming languages. This Short Cut also helps you protect your live applications by describing how to monitor for and block attacks before your data is stolen. Hacking is an increasingly criminal enterprise, and web applications are an attractive path to identity theft. If the applications you build, manage, or guard are a path to sensitive data, you must protect your applications and their users from this growing threat.

The goal of database performance tuning is to minimize the response time of your queries. It is also to optimize your server’s resources by minimizing network traffic, disk I/O, and CPU time. This IBM IBM Redbooks publication helps you to understand the basics of identifying and tuning the performance of Structured Query Language (SQL) statements using IBM DB2 for i5/OS . DB2 for i5/OS provides a comprehensive set of tools that help technical analysts tune SQL queries. The SQL Performance Monitors are part of the set of tools that IBM i5/OS provides for assisting in SQL performance analysis since Version 3 Release 6. These monitors help to analyze database performance problems after SQL requests are run. In V5R4 of i5/OS iSeries Navigator provides a series of new tools to do SQL Performance analysis that we cover in this book. Among the new tools that we will covering are:

Since the enormous number of features made available with MySQL release 5.0, MySQL has been gaining steam as a viable alternative to database behemoths like Oracle and IBM DB2. MySQL users now have the ability to extend MySQL with new SQL commands, optimize query execution, and embed MySQL within low-resource environments like embedded devices and kiosks. Expert MySQL, by Dr. Charles A. Bell, is the first book to examine these opportunities in detail, showing you how to wield maximum control over this powerful open source database. You'll learn how to create your own custom storage handlers, ensuring maximum flexibility and speed within your specialized applications. You'll also gain valuable insight into MySQLs architecture and learn how to tweak its behavior through custom changes to the source code.

Compared to industrial-strength database products such as Microsoft's SQL Server, Access is a breeze to use. It runs on PCs rather than servers and is ideal for small- to mid-sized businesses and households. But Access is still intimidating to learn. It doesn't help that each new version crammed in yet another set of features; so many, in fact, that even the pros don't know where to find them all. Access 2007 breaks this pattern with some of the most dramatic changes users have seen since Office 95. Most obvious is the thoroughly redesigned user interface, with its tabbed toolbar (or "Ribbon") that makes features easy to locate and use. The features list also includes several long-awaited changes. One thing that hasn't improved is Microsoft's documentation. To learn the ins and outs of all the features in Access 2007, Microsoft merely offers online help. Access 2007: The Missing Manual was written from the ground up for this redesigned application. You will learn how to design complete databases, maintain them, search for valuable nuggets of information, and build attractive forms for quick-and-easy data entry. You'll even delve into the black art of Access programming (including macros and Visual Basic), and pick up valuable tricks and techniques to automate common tasks -- even if you've never touched a line of code before. You will also learn all about the new prebuilt databases you can customize to fit your needs, and how the new complex data feature will simplify your life. With plenty of downloadable examples, this objective and witty book will turn an Access neophyte into a true master.

Microsoft SQL Server Analysis Services provides fast access to data by means of multidimensional data structures and the multidimensional query languag MDX.

XML represents a fundamental change in computing. It allows applications to move away from proprietary file and data formats to a world of open data interchange. XML has become ubiquitous not only because of its range of applications, but also because of its ease of use. Although XML solves many problems by providing a standard format for data interchange, some challenges remain. In the real world, applications need reliable services to store, retrieve, and manipulate data. These services have traditionally been offered by DB2 for i5/OS. In this IBM Redbooks publication, we discuss the challenges of representing XML hierarchies in the relational database model. We provide an in-depth explanation of the three most popular approaches to bridge the hierarchy, the relational model dichotomy: Programmatically process the XML documents and map their hierarchy into a relational database. Use database middleware to handle the XML parsing and XML-to-relational database mapping. Use Extensible Stylesheet Language (XSL) Transformation to transform inbound XML documents directly to SQL scripts. We also share best practices and techniques aimed at streamlining the XML and DB2 for i5/OS integration. Please note that the additional material referenced in the text is not available from IBM.
