3.6 Architectures of HIS.

Typical architectural styles at logical tool layer of HIS.

Typical architectural styles at physical tool layer of HIS.

Architectural styles at logical tool layer

Logical tool layer : application component die de ziekenhuis functies steunen worden beschreven.

• DB1 style

• DBn style

Page 4: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

DB1 Style

1 application component bevat 1 database system.

Page 5: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

DBn Style

n-aantal application components met hun eigen database system.

Page 6: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

DBn Style

• Vb. Administratief patient data - naam - geslacht - geboortedatum Radiological Information System - wat voor scan voor wie - op welke dag een patient

Page 7: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

DBn Style

• “ Spaghetti “ architectural style

• “ Star “ architectural style

Page 8: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

“ Spagetti “ style

Direct verbinden van application components die data willen verwisselen

Page 9: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

“ Star “ style

Software component die verantwoordelijk is voor de communicatie tussen application component.

• Vb. Communication server

Page 10: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

Architectural style at physical tool layer Physical tool layer : set van physical data

processing components

• Mainframe-based architecture bestaat uit meerdere mainframe system

waaraan poorten zitten

Poorten: om toegang te krijgen tot een application component

Page 11: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

Architectural styles at physical tool layer

• Client-server architecture meerdere central servers zijn onderling

verbonden door een netwerk

Page 12: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

3.7 Integrity&Integration within HIS

Integrity : correctheid van data

• Formal integrity - object identity - referential integrity

• Content integrity

Page 13: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

Formal Integrity Object integrity : een bestaan, afzonderlijk

van waarde• Vb. PIN, case identification number.

Koppelen hiertussen : referential integrity

Page 14: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

Content Integrity

Dezelfde data in verschillende application components op dezelfde manier geintepreteerd.

• Ondersteunt door medical data dictionaires, MDD

Page 15: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

3.7 Integrity&Integration within HIS

Integration : maakt een geheel van verschillende delen.

• Data Integration• Access Integration• Presentation Integration• Contextual Integration

Page 16: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

Data Integration

Data dat is opgenomen, is beschikbaar waar het nodig is, zonder opnieuw in te voeren.

• Ondersteunt door communication servers. - HL7 patient- and case-based messages - DICOM transfer of images

Page 17: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

Access Integration

De application components dat nodig is om een bepaalde taak uit te voeren is beschikbaar waar het nodig is.

• Vb. PMS nodig voor opnemen patient,systeem ook beschikbaar op plekken waar je een patient kan opnemen

Page 18: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

Presentation Integration

Verschillende application components representeren data op een andere manier.

• Vb. Geslacht van patient met bepaalde kleur

Page 19: 3.6 Architecture of HIS.  3.7 Integrity & Integration                within HIS

Contextual Integration

Context blijft bewaard ook al is de application component veranderd.

• Vb. Patientgegevens hetzelfde als van radioloog naar KNO-arts gaat.
