While you are annotating an XML schema in the IBM XML Schema Mapping Designer, you can hide DB2® tables and map links in the right pane to clear your work area. If you want to see all the tables and map links in an annotated XML schema, you can redisplay the hidden tables and map links at any time.
Requirement: An annotated XML schema must be open in the IBM XML Schema Mapping Designer, with one or more DB2 tables or map links previously hidden.
To show hidden tables and map links:
All the tables and map items that you hid previously are redisplayed in the right pane. If any tables overlap, you can move them to rearrange their order.
