If you want to use inheritance to create "Iterating Business Objects", you can now extend Recordset instead of delegating iteration to a composite Iterator. Recordset provides similar methods to an ADO Recordset, hence the name. Recordset is not a query, but rather a query that is converted to an array of structs. Extending Recordset is useful as an alternative to maintaining an array of objects, or if you want to display a list with calculated fields (an employee has
a startdate, but display format is "years of service").
