Specify where the database lives using the web.config file connection settings. make sure that the Context Name is your Connection String Name as below:

XML

<connectionstrings>
        <add name="YourContextName"
         connectionString="Server=aaaServer;Database=aaaDB;Uid=aaa;Password=aaa; " 
         providerName="System.Data.SqlClient"/>
</connectionstrings>

Entity Framework Code First allows you to create data model classes prior to creating a database. When you run the application for the first time, a database is created for you on the fly based on the classes you created. Database initializers allow you to decide a strategy of database creation and seed data generation. Code First provides its own set of database initializer classes and also allows you to create your own.
