关于XML和SQL的一个练习毕业设计外文资料翻译.doc

附录A外文翻译-原文部分 An Exercise about XML and SQL What This Exercise is About XML is found in more and more applications today. With its non-proprietary format, XML can be used to represent and exchange information in an application. The information for most applications is stored in some fashion. A relational database is the most common location for persisting information. With databases storing information and XML used for representing information, a relationship exists between the two technologies. WebSphere Studio Application Developer has tooling that supports this relationship as well as individual relational database design tools and XML authoring tools. There are tools for working with existing databases schemas or creating new database schemas. There are also editors for specific types of XML documents. In this exercise you will use some of the XML tools and some of the features in the Data Perspective in WebSphere Studio Application Developer. User Requirement User must have DB2(version 7.2) and WebSphere Studio Application Developer installed. The Invest database must be setup (c:\yourbank\lab5\dbsetup.bat) and the source files used in the lab must be available at c:\yourbank\Iab5. What You Should Be Able to Do After completing this lab you should understand how to connect to an active database and import the schema into WebSphere Studio Application Developer. You should be able to add foreign keys to a table schema. By the end of this lab you will also be able to create SQL statements from multiple tables using the SQL statement wizard. Finally，you should be able to use the XML to SQL wizard to query the active database and return the information in an XML document. With the XML results，you will use the XML to XML mapping wizard to translate the results to another XML format.
