I have an existing J2EE application with an Oracle database.
The Oracle database is replicated. Due to replication and performance issues, not all tables have a foreign key constraint *even* though a record may refer to other records. They have a "logical" foreign key.

As I'm new to Hibernate, I would like to get some feedback on this issue (or non issue). I don't think the lack of foreign key constraints in the schema will make any difference. In a Hibernate entity xml file, I should just point to the column in the table which is the "logical" foreign key.
The fact that the database schema doesn't specify it is irrelevant.

Please confirm.

Correct.
