What are the differences between the CodeFirst and DatabaseFirst approaches when working with ORM?

The approaches CodeFirst and DatabaseFirst when working with ORM differ in where the development starts and how the model and database are synchronized:

• CodeFirst: the developer first describes models (classes) in code, and then ORM generates the database structure based on these models. This is convenient when the database is created from scratch or when you want to manage the schema through code.

• DatabaseFirst: a database is created or an existing one is used first, and then ORM generates models and context based on the database structure. This approach is convenient if the database already exists or is designed separately.

Example in C# with Entity Framework (CodeFirst):

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class AppDbContext : DbContext
{
    public DbSet<Product> Products { get; set; }
}

Then, a database is created using migrations.
