Perl DBI wrapper and abstraction layer

 Rose::DB is a wrapper and abstraction layer for DBI-related functionality.
 Instead of dealing with "databases" that exist on "hosts" or are located via
 some vendor-specific addressing scheme, Rose::DB deals with "logical" data
 sources. It supports technologies like the Rose::DB::Object object-relational
 mapper system (see librose-db-object-perl for details).
