This mode realizes the integrated management of investigation data, reports, charts, images and other information. It not only meets the management integration requirements, but also provides the basis for knowledge discovery, expert database and other senior application. Based on the actual system construction as an example, this paper introduces the architecture model, function implementation and system integration of the management information system.
