For me a CRUD application has none or very few business rules and a simple data model. I sometimes look an application and think that it could probably be written with a generic CRUD app with a few customisations, perhaps a list of data elements. An app is no longer CRUD when you have: 1. more than a couple of SQL statements (other than CRUD!) 2. are implementing a business process (multiple steps, multiple people) 3. you are performing calculations or analysis
