I corrected the connection test as you suggested, don't know how that slipped by.
Your second point is a good one, but eliminates the need for Class::DBI in that context. Class::DBI is not an end all be all for relationship integrity management. Class::DBI can however be used to manage relationships in situations where
"You said nothing about how DBI::Class handles queries with one or more JOIN"
- The management of relationships has to be done at an application level vs. the database (somewhat database engine agnostic design)
- The the database doesn't support more robust features, for which there are numerous examples and converting table format isn't an available solution because *insert subjective reason here*
Yes Class::DBI has many features and transparent SQL is one of them, but they are not within the context of an introduction. I plan to release a mid range tutorial after I complete my present project using Class::DBI. I am open for suggestions and or tidbits of what should be included in that node.
