Due to the role dependency of the XML and paper based invoice standards this section
describes the ATL COM invoice request module suitable for the hospital.
Architectural blueprint
The input will be supplied through a programmatic
interface. Thereafter the data is transformed into a standards-compliant XML invoice stream that is
sent to the intermediate.
Alternatively, one can force the invoice module to send the input to a
print engine producing the appropriate invoice on paper.
As a side effect of the encapsulation the developers of the main software do not need to
care, format nor implement the XML invoice standard.
To ensure standards-compliance, an invoice module leverages validation services
provided by the companion
validator modules.
This is of particular value for invoices which
must comply with complex coding schemes such as Tarmed.
