I think you mean ORMs (object-relational mapper e.g DBIC, CDBI, RDBO,
Tangram, Hibernate etc) not RDBMS (relational database management 
system e.g. Oracle, DB2, Sybase, Postgres, MySQL, MSSQL) don't you?

In some ways you're comparing apples with Wednesday. What do you mean by
'full support'? DBIC has /some/ many-to-many relationship support - see
DBIx::Class::Relationship - has_many(), belongs_to(), many_to_many().
If you can express a query you'd perform in SQL, you can use DBIC's
SQL::Abstract support to perform a join that isn't directly supported by
the higher level API.
