Good if you want many data columns without touching db schema.
Excellent module. If you have a large database and don't want to spend time for ALTER TABLE ADD SOME UNIMPORTANT COLUMN, this module will help you. Also, with DBIx::Class::DynamicSubclass it allows make a lot of cool features.
Rated 1 as a result of the author rating his own module 5. I haven't used this module.
Very good module for storing dynamic data range
