It’s probably just a function of the apps I happen to have worked on, but I have rarely (maybe never?) seen ORMs pay for themselves by the end. The classic joke

It’s probably just a function of the apps I happen to have worked on, but I have rarely (maybe never?) seen ORMs pay for themselves by the end. The classic joke about the business is that they see all of the costs and none of the value. But the developers tend to see all of the value and none of the costs. And the costs of ORM on a project have a very long tail. For most projects, if you really want to control what and how the developers interact with the database, a better approach is to have one or more separate db developers who create an API for the data via stored procedures.
