Relationship Maintenance

The relationship maintenance phase of a reorganization restores the referential integrity defined by the rules of the latest schema definition and includes the following actions.

• Adding an inverse

• Removing some, but not all, inverses from a relationship (that is, after the change, inverses still exist between the properties involved)

• Condition maintenance

• Inverse definition changes; for example, changing the inverse-required option

• Changes to dictionary specifications; for example, key definitions or the no-duplicates constraint

• Changes to the physical attributes of a collection; for example, block size and expected population

• Validation of the member objects of a collection against its member type definition

• Validation of reference property type changes

• Moving exclusive collections up or down the class hierarchy
