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;

Can benefits of a Grid environment for the better performance.
For the wrappers alocation in Grid nodes. For the independent execution For the distributed execution of the QEP (Query
Execution Plan)
PACS/Data Integration Systems

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;
