Oracle Apps 11i, Release 11.5.4 and earlier - Relational Constructs.

Are relational structures such as primary keys, foreign keys, and alternate
candidate keys (i.e. unique indexes) enforced with application code, or are
they enforced through the dbms?  Is there an application data dictionary
that acts as a virtual replica of dbms data dictionary, or does 11i ensure
that the dbms enforces these conventions by prividing the definitions for
ddl upon installation/migration?



Thanks in advance,



Dan
