The Careflow architecture. A case study in medical transcription

The Careflow architecture uses Java and CORBA to streamline transcription at many hospitals and clinics. In this article, I explore the evolution of this middleware solution for automating the archiving, versioning and routing of documents in transcription. After a brief overview of transcription, I explain the project's architectural goals and describe three successive versions that our team developed. Finally, I explore lessons learned and reasons for changes to the system over the past decade.
