The case for explicit data schemas
The data schema is important to more than just your current notion of your application. It may be worth designing the schema explicitly.

The software development Zeitgeist seems to be pointing away from the necessity of having explicit data schemas. Nowadays, designing a database schema, or even just an ER diagram, seems to be downright old-fashioned, and an activity that is viewed more as a burden or a restriction, rather than something of value. At the risk of being labeled a contrarian, I would like to make the case in favor of explicitly designing data schemas.
