Yes, that's correct. You cannot exactly model this in TimesTen. You need to omit some of the relationships so that things are defined in TimesTen as a pure parent/child relationship. You may also consider putting the tables into separate cache groups. Of course, there are some consequences to doing this:
1. The 'missing' relationship cannot be enforced by TimesTen. The application must enforce/respect it. If it does not some updates may fail to propagate to Oracle if they violate the relationship in Oracle.
2. If parallel AWT is configured (to improve propagation performance) it will not be used for any tables where there are missing relationships. All updates to those tables will be applied sequentially.
