 When you need additional fields in your application, you can always add them in your [service model definition](../service-builder/service-builder-basics/generating-model-persistence-and-service-code.html#examine-the-service-model-definition) and re-run Service Builder. This adds new columns to your database table. This works, but can be a pain: now you have to write an upgrade process to migrate your users to the new schema.
