A method of operating a centralized healthcare management system that includes a data translation map database and a central interpolation server computer interconnected to a computer network. The central server receives an initiating request from a requesting terminal for a data record to be retrieved that satisfies a specified condition; then sends a data record request to a source database; then receive a data record from the source database, with the data record being in a source format. The central server references a data translation map database for a desired translation map, with the data translation map enabling the central interpolation server to translate data records from a source format to a destination format. The central interpolation server translates, in accordance with the selected data translation map, the received data record from the source format into a destination format suitable for transmission to the requesting terminal. The central server then transmits the data records in the destination format to the requesting terminal via the network.
