Service Orientation: Processes andservices
SoberITSoftware Business and Engineering Institute
HELSINKI UNIVERSITY OF TECHNOLOGY
SOA and MDM, but which to choose?
“The promise of Service Oriented Architecture (SOA) forbusiness processes are cost reductions and improvedagility through reuse of modular business servicesimplemented with Web Services technology.”
SOA Principles: Loose coupling, Encapsulations, Independence
“The promise of Master Data Management (MDM) arereduced integration costs and improved businessproductivity through use of consistent data accrossdifferent applications of the enterprise.”
MDM Principles: Sharing common data and definitions, avoidingduplication
Is there a dilemma between this two approaches?

Processes and services
Care Processes
Diagnostic services
Generic services
Enterprise service bus
Applications withinterfaces

SOA example: The care process andservices
Electronic HealthRecord
Invoices
Secondary useinformation:statistics etc.
SOA terminologyBusiness Process: Care ProcessBusiness Services:
Lab tests, radiology tests, endoscopy tests etc...Procedures, Medication, TherapiesMedication orders, therapies etc are requested servicesA care process consists of multiple services

The need for a common informationmodel
Shared understandingbetween the businessprocesses andbusiness services
Who: Organization,person

Where: Location, addressHospital, Ward, Laboratory
What: ItemWhat to do, what to order,what to invoice, what arethe results

Aggregations
Aggregations: ActRelationship.
Pairs of keys of related acts
Instance of a process
Instance of a service
For example: Encounter and relatedexamination
Keys of instances should beconsidered as important masterdata, which need to be providedby the collaborating applications
What services were needed to produce theresults of an instance of an process?Aggregations are needed for example
Electronic Patient Records: Examinationsrelated to an encounter
Data Warehousing: All examinations related toan encounter
Examination Id
Encounter Id
(Encounter Id, Ecxamination Id)

The applications expose the services
Every application has its own master data

Unmanaged, replicated master data
Master data is managed separately in each systemsSame concept can have different codes, same codes canmean different conceptsThe field names and field values do not matchChanges are not propagated in syncObsolete codes still existNo clear responsibilities or ownership of master dataNo history trackingResult: Increasing Maintenance Costs, dereasingmaintenance productivity

Master Data ServicesCreate and update services for the owners of master dataUsing Master Data services for the users of master data
The actual physical implementation of master data is encapsulatedbehind the servicesThe master data services may be used within other servicesApplications are not using their own code tables in their own databasesbut master data services
