This XML Fundamentals training introduces you to the basics of XML. In this 2 day hands on course, you will learn the central XML technologies, including writing well formed and valid XML, creating Document Type Definitions (DTDs) and XML schema documents and using XPath and XQuery.

Learn To:

• Create well-formed and valid XML documents.
• Use XML Namespaces in an XML document to resolve name ambiguities in XML documents.
• Create Document Type Definition and XML schema documents to validate XML documents.
• Use XPath expressions and functions to find and select nodes in XML documents.
• Transform XML documents by using stylesheets and XPath expressions.
• Use Oracle JDeveloper to view, create, edit, and test XML and other XML-related documents.
• Use XQuery to query, generate, and transform XML content. 
• Identify the features and benefits of Oracle XML DB

XML schema

This course covers the components of an XML schema, how to create and XML schema document and how to validate XML documents using XML schemas. Validating documents using Document Type Definitions (DTDs) are discussed as well.

Benefits To You

Additionally, you’ll be introduced to the support for XML offered in various Oracle products, like the Oracle XML DB and Oracle JDeveloper. Use the XQuery XML query language, which is built on XPath expressions, to query data from both XML files and relational databases. Review how to use XQuery to generate and transform XML content. You’ll learn how to use the XML concepts while exploring XML Namespaces that are used to apply uniqueness to elements.

This course introduces students to Oracle XML DB, a feature of the Oracle Database. Students learn to store, retrieve, generate, and manipulate XML data in Oracle Database 11g. 

Students learn about the different storage models for storing XML documents in Oracle XML DB. Students query XMLType data by using SQL/XML standard functions and XQuery. Students generate and manipulate XML data and learn to use Oracle XML DB Repository. In addition, students access and manipulate repository resources using protocols such as SQL, and PL/SQL. Students learn to manage changes in an XML schema after registering it with Oracle XML DB. Students also learn how to import and export XML data.

Oracle SQL Developer is the major development tool in this course. SQL*Plus is also available as an optional tool.Learn To:

• Store and retrieve XML Data in Oracle XML DB
• Generate XML Data from relational data in the database
• Use XQuery to query, generate, and transform XML data
• Manipulate XML Data in Oracle XML DB
• Use Oracle XML DB Repository
• Export and Import XMLType Data
