various core areas of databases and information systems. Besides collaborative research efforts there are
also research efforts with the Computer Security Research
Laboratory, the Software Engineering
Laboratory, the Visualization and Graphics
research group, the Medical Informatics
Group, and the Center for
Spatial Technologies And Remote Sensing (CSTARS). More detailed
