Relationship Mapping Wizard Overview
See Also
When you have foreign-key relationships between database tables, you will usually
want to preserve those relationships in the CMP beans mapped to those tables.
The Relationship Mapping wizard lets you determine how relationships between
mapped CMP beans are stored in the database. Relationships
enable navigation from one bean to another in the same way that a foreign
key enables navigation from one table to another.
The Relationship Mapping wizard takes you through the following steps:
- Establish relationships between related beans and fields.
- Link the mapped tables directly in a 1-1 or 1-n relationship, or using a
join table.
- If you link the mapped tables using a join table, the next step is to map
the relationship field to a key, either local or foreign.
