The type tree analyzer validates the data definitions for internal consistency. The
results of the analysis indicate whether your data definitions are sufficient to
distinguish the objects in your data stream. The analysis indicates if something in
your data definition may prevent accurate data mapping.

Logical analysis addresses the integrity of the relationships that you define.
Structural analysis addresses the integrity of the underlying database. Typically,
you should not encounter structural analysis errors.
