Is there any issues in using version 2,to get the same results as version 1. Or is this just bad coding.

Any Ideas

public class Customer { public int CustomerID { get; set; } public string EmailAddress { get; set; } int Age { get; set; } }

public interface ICustomer
{
    void AddNewCustomer(Customer Customer);
    void AddNewCustomer(string EmailAddress, int Age);
    void RemoveCustomer(Customer Customer);
}

public class BALCustomer
{
    private readonly ICustomer dalCustomer;
    public BALCustomer(ICustomer dalCustomer)
    {
        this.dalCustomer = dalCustomer;
    }

    public void Add_A_New_Customer(Customer Customer)
    {
        dalCustomer.AddNewCustomer(Customer);
    }

    public void Remove_A_Existing_Customer(Customer Customer)
    {
        dalCustomer.RemoveCustomer(Customer);
    }

}

public class CustomerDataAccess : ICustomer
{

    public void AddNewCustomer(Customer Customer)
    {
        // MAKE DB CONNECTION AND EXECUTE
        throw new NotImplementedException();
    }

    public void AddNewCustomer(string EmailAddress, int Age)
    {
        // MAKE DB CONNECTION AND EXECUTE
        throw new NotImplementedException();
    }

    public void RemoveCustomer(Customer Customer)
    {
        // MAKE DB CONNECTION AND EXECUTE
        throw new NotImplementedException();
    }


}

//          VERSION 2 

public class Customer_New : DataRespository<CustomerDataAccess>
{
    public int CustomerID { get; set; }
    public string EmailAddress { get; set; }
    public int Age { get; set; }
}

public class DataRespository<T> 
    where T:class,new()
{

    private T item = new T();
    public T Execute { get { return item; } set { item = value; } }
    public void Update()
    {
        //TO BE CODED
    }

    public void Save()
    {
        //TO BE CODED
    }

    public void Remove()
    {
        //TO BE CODED
    }
}



class Program
{
    static void Main(string[] args)
    {
        Customer_New cus = new Customer_New()
        {
            Age = 10,
            EmailAddress = "[email protected]"
        };

        cus.Save();
        cus.Execute.RemoveCustomer(new Customer());

        // Repository Version

        Customer customer = new Customer()
        {
            EmailAddress = "[email protected]",
            CustomerID = 10
        };

        BALCustomer bal = new BALCustomer(new CustomerDataAccess());
        bal.Add_A_New_Customer(customer);
    }
}

}
