Hi Helmut

Hi Chandra,

I think there are at least two reasons.

1. It is not quite easy to write such a model generator. Think about Joins, complex where or having clauses, ...

2. Normally you do not get data from just one table and display or edit that data. In real world there are different tables involved in an operation. There is business logic around theses tables and business logic shouldn´t be placed into the controller. According to MVC pattern business logic should be placed into the model and that is an EJB, RFC or Web Service.
