Annotated XML schema decomposition can become complex. To make the task more manageable, you should take several things into consideration.
Annotated XML schema decomposition requires
you to map possibly multiple XML elements and attributes to multiple columns
and tables in the database. This mapping can also involve transforming the
XML data before inserting it, or applying conditions for insertion.
The following are items to consider when annotating your XML schema, along
with pointers to related documentation:
- Understand what decomposition
annotations are available to you.
- Ensure, during mapping, that the type of the column is compatible with the XML schema type of the element or attribute
it is being mapped to.
- Structure your XML schema to minimize
demands made on system memory resources.
- Ensure complex types derived by restriction or extension are properly
annotated.
- Confirm that no decomposition limits and restrictions are violated.
- Ensure that the tables and columns referenced in the annotation exist
at the time the schema is registered with the XSR.
