Totally agree that schemas are lifejackets. Carfully modelled data can outlive the application it was originally written for. Poorly structured data, on the other hand, where the schema and consistency is enforced in code is much harder to migrate. Maybe our problem is that we write systems with a disposable point of view? We don't even think the system will be around long enough to require migration.
