Abstract
Today, most health managers have more information available to them than they can properly use. Map-linked data bases (MLDBs) can allow a more thorough understanding of existing information. The packaging of information can substantially increase its influence. A brief history of computers in health information management is presented in general terms, including experiences gained by WHO in introducing map-linked data bases into its work. After the introduction of graphs and charts into information presentation, maps produced in this way promise timely and increasingly meaningful ways for the information specialist to present the health manager with the information needed to make decisions and take action. Some applications of MLDBs are presented and discussed, including examples of how they are being used.
