## Code First or DataBase First?

Entity Framework will use a model of the database, that our application will *consume*.
There are several approaches to obtain it

### Code First

We will define the Objects that we will manipulate via classes, and we will create the database from this model

### DataBase First

The database exists before the development of the application, and we will use tools that will *generate* the corresponding classes.
