Implementing factory pattern without abstract class

I'm trying to implement a factory pattern in my project, but it seems to work even without an abstract class behind it.

What am I doing wrong?

1)Product

public interface IDataBaseEntity
{
    string ServerName
    {
        get;
        set;
    }
    string Id
    {
        get;
        set;
    }
    string Password
    {
        get;
        set;
    }
    string Database
    {
        get;
        set;
    }
    DataTable GetBarCodeTable();
}

2)Concrete Product

class SqlEntity : IDataBaseEntity
{
    SqlController sqlController = new SqlController();
    public string ServerName { get; set; }
    public string Id { get; set; }
    public string Password { get; set; }
    public string Database { get; set; }
    public string CurrentTable { get; set; }

    public DataTable GetBarCodeTable() 
    {
        return sqlController.ExtractBarCodeTable(this);
    }
}

3)Creator

 IDataBaseEntity dataBaseEntity = null;
        private void Form2_Load(object sender, EventArgs e)
        {

             dataBaseEntity = CurrentEntity.GetCurrentIdentity();

            barcodeView.DataSource = dataBaseEntity.GetBarCodeTable();
        }

4)Concrete Creator

public static class CurrentEntity
    {
       public static IDataBaseEntity GetCurrentIdentity()
        {
            SqlEntity sqlEntity = new SqlEntity
            {
                ServerName = @"localhost\test",
                Id = "sa",
                Password = "psw",
                Database = "dbname"
            };

            return sqlEntity;
         }
}

In this way I can keep the user code separated from the implementing code, but i'm not using any abstract class. Where's the catch?
