SQLXML is a middle-tier COM component that can compose relational data into XML data by using annotated XSD schemas and XML views. Annotated XSD schemas declare a mapping between an XML schema and a relational schema so that SQLXML components can infer the relational operations to execute on the database based on the operations executed against the XML structure. SQLXML provides a managed API that provides Command, DataAdapter, and Parameter classes that specialize in querying annotated XSD schemas. The SQLXML API is defined inside the Microsoft.Data.SqlXml DLL. SQLXML XML view files provide an easy way to manage the format of the resulting XML of multiple Transact-SQL and XPATH queries within the same file.

1. What is the mechanism you use to define a mapping between the XML schema and a relational schema that enables developers to manipulate relational data without having to write Transact-SQL code A. exist() method B. XML schema collection C. Annotated XML schema D. Relational schema 2. What are the main benefits of using XML views and annotated XML schemas to query XML data (Choose all that apply.) A. XML views and annotated XML schemas validate your XML. B. They are stored as files on the file system, so you don t have to recompile the application if you change the files. C. The XML rendering happens where you deploy the XML views and annotated XML schemas, which can be on a different machine than the database server. D. XML views and annotated XML schemas compare the original and current views of the XML data and automatically create the required Transact-SQL commands to synchronize the changes from the XML data into relational data in the database.

Lesson 4: Modifying XML Data
Lesson 4: Modifying XML Data
SQL Server 2005 offers two technologies that give you the capability to modify an XML instance by deleting, adding, or updating nodes in the XML structure or by changing the node contents. The XML data type implements XML data manipulation language (XML DML) as an extension to the XQUERY and XPATH expressions already supported. And the SQLXML middle-tier API gives you the option of using updategrams, so instead of declaring the actual queries to execute, applications just need to provide the final view of the XML instance. By comparing the original and the final versions of the XML structure, SQLXML can formulate the set of Transact-SQL operations required to synchronize the XML data with the relational data. This lesson covers the most important techniques for updating XML data in SQL Server 2005 and, when appropriate, provides references to external documentation so that you can learn more about a specific feature. All the code examples in this lesson use the AdventureWorks sample database installed by the SQL Server 2005 Setup.
After this lesson, you will be able to:
Choose whether to use the XML data type or SQLXML to modify XML data. Use the modify() method of the XML data type to insert, modify, or delete XML content and XML structure elements. Use SQLXML updategrams to generate Transact-SQL INSERT, UPDATE, and DELETE statements without writing any Transact-SQL code.
Estimated lesson time: 30 minutes
Real World
Adolfo Wiernik Previous versions of SQL Server did not provide a way to update XML data at the node level. The only technology available was SQLXML updategrams, which are covered in this lesson. But updategrams enable you to modify relational data represented as XML data. Updategrams provide modification capabilities for data viewed as XML and not stored as XML. Another possibility was to use OPENXML, convert the XML structure into a tabular format, update it, and then convert it back into XML. Of course, this caused heavy processor and memory usage. The last and easiest solution was to update the XML data by using a middle-tier technology such as Document Object Model (DOM) or Simple API for XML (SAX), but this meant that the database was not aware of the changes being made.
