Maintaining a model feature in three places, the SQL, the class and a manual mapping, violates the basic principles of database modelling (store facts once), at the meta level (rather than the data level). ORM is a flawed attempt to remedy this. It is flawed because client/server sql databases create a distributed system, and distribution is hard to abstract away. Other solutions solution are to ditch the SQL model (something like bigtable, db4o or Gemstone?), or to ditch the object model (something like PHP or Access?). |
