Agenda

Introduction; Data Integration Middleware Systems; PACS; Proposal; Conclusions.

Introduction Increase of heterogeneous and distributed data and

PACS; Demand: necessity of integrated PACS, HIS and RIS; Solution: PACS and Data Integration Middleware

Systems;

4

Data Integration Middleware Provide from distributed and heterogeneous data

sources a single, uniform and homogeneous vision.

Developing data integration middleware systems is not a simple task, due to the complexity of:

Supporting multiple data models; Data semantic integration ; Query processing strategies; Transaction control techniques;

Conclusions Despite the existence of a data integration middleware,

it’s need adapt some layers in order to integrate other existing projects;

Need greater knowledge in the field of medicine; Improving the use of hospital information systems in

HUCAM and the others hospital;
