Rose::DB is a wrapper and abstraction layer for DBI-related functionality. A Rose::DB object "has a" DBI object; it is not a subclass of DBI. Please see Rose::DB::Tutorial for an example usage scenario that reflects "best practices" for this module. Are you looking for an object-relational mapper (ORM)? If so, please see the Rose::DB::Object module. Rose::DB::Object is an ORM that uses this module to manage its database connections. Rose::DB alone is simply a data source abstraction layer; it is not an ORM.
