Abstract: An information processing system for consulting centralized information originating in operational applications including a server and a plurality of microcomputers that issue requests to the server. The server includes data stored in the form of files and a metadictionary developed around a plurality of tables specific to the documentation and the administration of the system. Notably, the data is organized in domains, subdomains and functions, and are analyzed by a logical process contained in the metadictionary, which includes axes and indicators that describe the applications. The logical process makes it possible, at the moment the data to be imported into the server is defined, to create tables that contain the data of complementary tables, called consolidation tables, to authorize a generic response to all the requests made of the data and to optimize access performance.
