1. A system for an aircraft platform implementing a set of avionics functions using a plurality of heterogeneous hardware and software components, the system comprising: an acquisition module for acquiring operating parameters of the components, configured to implement a plurality of communication protocols each configured to query a respective component of the heterogeneous hardware and software components; a storage module including a database, configured to collect and store the operating parameters acquired by the acquisition module in the database in response to a request made by a client; an interface module for interfacing with a plurality of clients, including a query unit configured to query the database of the storage module and supply several of the operating parameters acquired by the acquisition module from several different components using several different communications protocols, causing a client monitoring application for the client to display the several operating parameters using a same graphic interface in a format selected by the client monitoring application; and wherein the acquisition, storage and interface modules are arranged in a three-tier architecture comprising a lower tier in which the acquisition module is arranged, an intermediate tier in which the storage module is arranged and an upper tier in which the interface module is arranged.
