Class Table Inheritance implementation
I know that Rails uses the Single-Table Inheritance as mentioned in the wiki (http://wiki.rubyonrails.com/rails/pages/SingleTableInheritance).

Table Inheritance based on a function
Hello, we have a problem in a CMS project that we believe is basic for RoR developement and could concern others as well - or have already: RoR implements the ''Single Table Inheritance'' (STI) Pattern: http://www.martinfowler.com/eaaCatalog/singleTableInheritance.html .. through its ''ActiveRecord'' ORM. The Fowler example mentions a ''type'' column and RoR implements this directly - which we consider inconsistent with DB abastraction: It forces a ''type'' column in the database followi...
