Bob Martin believes that Active Record pattern that maps data structures to objects may be a source of confusion. Even though it appears to be an object, it actually is a data structure, vulnerable to the addition of new types.

ActiveRecord fails the DRY principle, especially if your database doesn't follow Rails naming conventions. As well, ActiveRecord associations and validations are redundant specifications of database constraints. Bryan wants to avoid (as much as possible) the situation where he's averse to making changes to his database schema, because of the resulting effort to change his app code.
