Refresh database is an workflow that allows you to develop with a migrations framework, but deploy with SQL files. It’s more than that, it allows you to rapidly make changes to your environment and sync up with other teammates. When I am talking about environment, I mean your local development environment: your code base and the local database back end you are hitting. Refresh database comes in two flavors, one for NHibernate and one for Entity Framework. I’m going to show you an example of the one for Entity Framework, which you can find in the repository for rh-ef on github. One note before we get started: This could work with any migrations framework that will output SQL files.
