I agree with much of what you say. One thing I’d like to append, though, about the persistence of enums: I don’t believe the generation of the enums at build time from the DB values is acceptable, but I also think that the runtime check is not a good solution. I’d define a third means: have a unit test which will check the values of the enum against the database. This prevents “casual” divergence, and avoids the overhead of checking the enums against the database every time the code is run.
