A new Object Request Broker architecture in implementing a medical picture retrieval system.

ABSTRACT

This paper describes the approach we used to implement the world wide web user interface of MediPict, a medical picture retrieval system. The best software architecture seemed to be the three-tier client/server architecture using Objects Request Brokers (ORB) which appears to have many benefits. Although CORBA appears to be the standard ORB, we found it more adequate to develop a different approach. This new ORB resolves many of CORBA's weaknesses (non coherent types, need of a static IDL, maintenance difficulties) by using the same language on the top and middleware tiers.
