c# - Exclude a field/property from the database with Entity Framework 4 & Code-First

I will like to know that is there a way to exclude some fields from the database? For eg:

public class Employee
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string FatherName { get; set; }

    public bool IsMale { get; set; }
    public bool IsMarried { get; set; }

    public string AddressAs { get; set; }
}

How can I exclude the AddressAs field from the database?

for future reference: you can use data annotations MSDN EF - Code First Data Annotations

[NotMapped]        
public string AddressAs { get; set; }
