Patient-centered information systems augment traditional approaches to health information management with specific functions designed to support patient participation in health care decision making and treatment activities. In addition to computer-based record systems and business management applications, patient-centered information systems must include functionality that support communication between clinician and patient, and that provide information and peer support in a timely fashion to the patient. Current progress in information systems demonstrates the existence and feasibility of consumer health informatics, patient access to computerized clinical records, and technical and organizational solutions to integrating computerized patient information systems. We are now proposing a model of patient -centered system that incorporates all those components, and provides a vision of the future.

Data warehouse technology is a new international pioneering research method which is developed by the urgent demands to adequately apply IT resources including Data Warehouse (DW), Data Mining (DM) and OLAP. The architecture and realization methods of an economic monitor and decision support system (DSS) based on DW are presented in this article.

Taking Wuhan City as an example, this paper studied the environmental emergency monitoring and management system (EEMMS) based on GIS technology systems and brought out the frame model of the system combined with the practice. The application of EEMMS model can provide fast, feasible methods for emergency monitoring in sudden environmental pollution accident and timely, effective, scientific technical support for decision-making of the environmental emergency management system.
