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 manual then describes ways you can store and retrieve XML data using Oracle XML DB, APIs for manipulating XMLType data, and ways you can view, generate, transform, and search on existing XML data. The remainder of the manual discusses how to use Oracle XML DB repository, including versioning and security, how to access and manipulate repository resources using protocols, SQL, PL/SQL, or Java, and how to manage your Oracle XML DB application using Oracle Enterprise Manager. It also introduces you to XML messaging and Oracle Streams Advanced Queuing XMLType support.
This Preface contains these topics:
This manual is intended for developers building XML Oracle Database applications.
An understanding of XML, XML Schema, XPath, and XSL is helpful when using this manual.
Many examples provided here are in SQL, PL/SQL, Java, or C, hence, a working knowledge of one or more of these languages is presumed.
Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.

Oracle Database Error Messages. Oracle Database error message documentation is only available in HTML. If you only have access to the Oracle Database Documentation CD, you can browse the error messages by range. Once you find the specific range, use your browser's "find in page" feature to locate the specific message. When connected to the Internet, you can search for a specific error message using the error message search feature of the Oracle Database online documentation.
