– Hoge beschikbaarheid
– Korte responsetijden
– Zeer korte doorlooptijd “proof of concept”

Aanpak
• Niet HL7v3 XML uitcoderen
• Op basis van schema’s
java code genereren
• Grote reductie in bericht
codeer fouten
• Maximale support van
java ontwikkelomgeving
• Herbruikbaar in andere
projecten

JAXB
• Met de JAXB xjc tool van alle .xsd (schema) files .java maken
• Omdat .xsd ook XML is patchen met .xslt (stylesheet)
• Resulteert in 581 .java files

Hibernate
• Krachtige mapping definities in XML
Collection mapping
Association mapping
Component mapping
Inheritance mapping
• Brede database support
Oracle, SQL-Server
• Objecten kunnen “lazy” geladen worden
• Hibernate houdt bij welke objecten zijn gewijzigd

Conclusie
• Goede tooling is essentieel
• Hard XML coderen is te “low level”
om HL7v3 te verwerken
• Trend om meer declaratief programmeren
• Meer fouten komen al compile-time
en niet pas run-time tevoorschijn
• Op basis van schemas (.xsd) java code genereren is een
goed hulpmiddel, nog enige workarounds nodig
