Chapter 5 Exchanging data with databases supporting XML
XSM User's Guide 217
Generating an annotated schema for Microsoft
SQL Server 2000
Microsoft SQL Server 2000 is an XML-enabled database server. It supports
annotations that can be used on XSD or XDR files, to map XML data to
relational data.
An annotated schema is an XML-coded file, targeted with an XML
language and tagged with specific DBMS annotations, that allows you to
store or retrieve data in an XML format, from relational databases supporting
XML. An XML model allows you to generate an annotated schema (XSD or
XDR) for SQL Server 2000. You need first to map an XML model to a
PDM, then to attach the Microsoft SQL Server extended model definition to
the mapped XML model. If need be, you can complete the mapping by
defining extended attributes to XML objects.
Mapping XML objects to PDM objects
There are several ways to map XML objects to PDM objects:
♦ Using the XML Builder Wizard (See following procedure)
♦ Generating an XML model from a PDM
♦ Generating a PDM from an XML model
♦ Manually
The best way to map an XML model to a PDM is to use the XML Builder
Wizard.
If you do not have a PDM, you can reverse engineer a database into a PDM.
For more information on reverse engineering a database into a PDM,
see chapter Reverse engineering in a PDM, in the PDM User’s Guide.
Caution
The following procedure assumes you have a PDM open in the workspace
and targeted with Microsoft SQL Server 2000 as DBMS.
If the PDM is not targeted with the proper DBMS, select
Database
→
Change Current DBMS.
