The diversity and the plurality of informations increase the data and knowledge dispersion to the manager. First restraints concern interfaces for end-user that often do not correspond to what is waiting by user and to user’s practices. Furthermore, some information systems are not communicated which makes impossible a synthetic view of a project. In this paper we present a system which allows unifying, representing, storing and visualizing in a unified and chronological view all information concerning a same – medical - project. This system guarantees the accuracy and relevance of the information and brings to the user useful information and events on the project sequence he is dealing with.
